Chapter 1: Meet the Players

Youkai Academy

The land was all but barren with the only plants as far as the eye could see being withered and crooked trees. The only animals which could be found were snakes, tarantulas, and enormous centipedes. Littered discriminately through the entire area was tombstones of many makes and sizes, all of them displaying a name and the dates of both birth and death. At the edge of the forest lay an enormous jagged cliff which gave way to a seemingly endless red ocean which hid a number of dangerous undersea beasts which could chew up and spit out a grown man. The only building in the immediate area was a large and expansive building which bore resemblance to a gothic mansion, complete with gargoyles, black roofs, and a depressing paint job. One would have thought that a reclusive millionaire would have called the area home. This was not the case. The building was in fact a school.

This was Youkai Academy.

Nestled inside a pocket dimension, Youkai Academy existed for the sheer purpose of teaching the younger generation of spooks, ghouls, and various monsters how to blend in and survive in the human world for the sheer purpose of maintaining the peace between the humans and the youkai. As with any school though, some of the students were less that well-behaved and as the case with monsters, that problem became ten times more difficult to deal with. Thankfully, Youkai Academy tended to take a more hands on approach when it came to discipline. Of course, the students were certainly permitted to take matters into their own hands should the case be dire enough.

BOOM!

Case in point…

The previously mentioned scraggly forests surrounding the monster school were alive with the sounds of battle as two groups of students began pummelling each other.

"YARGH!" a somewhat squat and green-skinned creature with a bald head, large nose, and yellow eyes cried as he was launched several feet away by a single blow. He wore a shredded school uniform with a red tie, green jacket, and brown trousers which looked like it had fit him at first, but then suddenly became shredded when he changed forms. In truth, all students of Youkai Academy were capable of maintaining a human form and it was against the rules to change to their true form in all but the direst circumstances.

The one who was fighting the goblin was a taller figure who was in a black bodysuit. His left ankle was adorned with a silver anklet while his right leg from foot to kneecap was covered in a silver boot which resembled bat wings and was chained shut. Around his waist was a red belt which had pouches on the sides which held objects that looked like whistles. The buckle was occupied by a round-faced bat which was black and gold with large red eyes. His torso was covered in silver armour which had a red front with black lines that outlined strong muscles. His shoulders were covered with more silver armour which appeared to be chained bat wings. His hands were covered with blood red armour which was pointed at the fingertips. Lastly, his head was protected by a red helmet with large yellow eyes which seemed like bat wings while his mouth was hidden by a silver mouth plate that had black fang-like markings on either side.

He was Kamen Rider Kiva, the King of Youkai Academy.

The goblin grimaced as he managed to get up before wiping his mouth, "This won't beat me, King! We will take your title!" Another battle cry sounded out and the goblin lunged at Kiva with his claws raised for a strike. Kiva quickly dodged the sloppy strike before launched a kick with his covered boot that dug into the goblin's gut, knocking him back into a tree where he lost consciousness with the impact. Opponent beaten, Kiva turned when he heard the sounds of battle echoing through the forests around him.

"Hiyah! Hah!"

Another goblin was taking swats at his female opponent, but her superior agility was allowing her to outmanoeuvre him…that and her obvious assets were distracting him.

She was a girl of slightly below average height who sported blue hair tied back in a loose ponytail with a purple scrunchie. She wore the school uniforms which consisted of a skirt and blouse, but rather than the jacket she wore a yellow sweater vest. However, it brought some attention to her larger than average breasts which bounced as she danced around her enemy. Her face was cute, accented by her blue hair while her legs were perfection, wearing white legwarmer socks with her shoes. However, she had large black bat wings coming out of her back, long nails on her fingers, and a black devil spade tail coming out from under her skirt.

She was Kurumu Kurono and she was a Succubus.

"Get down here, bitch!" the goblin shouted as he jumped at the hovering succubus.

"And you thought you could hit on me with a mouth like that?" Kurumu frowned as she dodged the jumping goblin before slashing at him with her razor nails. The strike cut through his cloths and skin, launching blood from the wound. Crying out, the goblin missed his landing and cracked his head on a rock, knocking himself out.

"Ha!" Kurumu laughed. "Teach you to try and lay a hand on me! That right is reserved solely for my Destined One!"

SHING!

Not far from Kurumu was another girl. She wore the school skirt, but covered her top with a long black and white sweater. Her skin was so pale it could almost be called snow white. She was cute and was rolling a lollipop in her mouth as she seemed to be completely at ease with the situation. What made her obviously a Youkai though were the large ice claws coming out of her sweater sleeves and the fact that her usually short purple hair had turned into purple-tinted ice.

Her name was Mizore Shirayuki and she was a Yuki-onna or Snow woman.

The reason that the teenage Yuki-onna wasn't fighting like Kurumu was that she had already beaten the goblin that was attempting to menace her. The squat, green monster was frozen within a large chunk of ice that had enveloped him completely. He would be fine after a few hours when the ice thawed out. He may have a cold afterwards, but he would be fine.

"Desu!"

With the two girls was a much younger girl who was around twelve, not usually seen around teenagers like the others. She was dressed in a brown outfit that didn't match the Youkai Academy school uniform at all. It was decorated with a brown cape and she even wore a witch's hat on top of her head. Gripped in her hand was a pink wand which had a heart with a crystal in the centre at the tip. She had short dark hair which just reached past her jawline and rather than fighting seriously, she seemed to be enjoying her battle.

The fact that she was making large pans and kitchen sinks fall out of the air on the goblin who was desperately dodging may have had something to do with that.

She was known as Yukari Sendo, the genius little girl who was also a Witch.

"PRGH!"

Last but not least was likely one of the most stunning out of all of the women there. She was a tall and regal beauty despite only wearing the average school uniform which consisted of a red skirt, white blouse, and green jacket. Her hair was shock white and reached all the way down to her perfect derriere. Her figure was lush and womanly, albeit not outright sexual like Kurumu's. Around her neck was a black choker with pearl decorations with a chain sticking out of the front. However, the choker itself seemed incomplete. Finally, her face was regal like the rest of her body, but her most notable features were her enlarged incisors and her red slitted eyes.

She was Moka Akashiya and she was the Queen of Youkai Academy.

The prideful vampire had just launched one of her trademarked kicks into the face of a noticeably fatter and taller than the rest goblin. The impact from the blow had knocked teeth clean out of the goblin's mouth before he was launched through several trees. The white-haired woman scowled at the trail of destruction that her target had made before turning her back to him, "As if some D-class trash could lay a finger on me." She glanced back to the goblin in the distance. "Know your place!"

KLONG!

"I got him! I got him!" Yukari cheered, finally having taken down her target with the sink she had made appear.

Kiva shook his head at the antics of those he called the most precious in his life. With the fight over, the tenseness in his body vanished as he approached the four girls. While he got closer though, the bat-shaped buckle flapped its wings and removed itself from his belt. Suddenly, Kiva's entire body turned into a quicksilver substance which shifted from his armoured form into the form of a regular teenage boy. Regaining his colours, the boy seemed to have brown hair and was a little thinner that what would be considered normal for the average boy. However, Wataru Kurenai was anything but weak in the eyes of the girls and the school at large.

Against his girls though…

"Wataru!" Kurumu squealed giddily as she lunged at her lover, trapping his face between her breasts while her succubus features receded into her body. Wataru immediately began to struggle for as pleasant as being in Kurumu's cleavage was, it made it somewhat difficult to breathe at times. "Did you see me? I kicked that smelly goblin's butt!"

KLONG!

A washing basin suddenly dropped from the air and onto Kurumu's head, making the busty girl go swirly-eyed as she stumbled away, allowing Wataru to breathe once again. Approaching the pair with a deep frown was Yukari with her wand raised high, "Get away from him boobzilla! Wataru-san can only be touched by me and Moka-san!"

SHING!

Yukari was suddenly frozen in another block of ice. Wataru gasped and moved to try and get her out, but suddenly felt a pair of arms wrap around him from behind. Glancing back, he saw Mizore's calm face with a very cute smile on her lips.

"Did you see me, Wataru?" the Snow woman asked hopefully. "I managed to beat mine first."

"That's…nice, Mizore-san," Wataru shivered, feeling the chill from Mizore's body since she just stopped using her ice powers.

"You and your concubines," Moka-sama sighed, perhaps in some amusement as she approached the duo with her hands on her hips. Getting closer, she eyed Wataru with an arched eyebrow. "You bring me out to fight goblins and not even an army of them? You should know that numbers are their only strength."

"Forgive me for not wanting them to lay even a finger on you," Wataru replied, holding up a silver cross which had a ruby embedded in the centre.

"So possessive my mate is," Moka-sama teased, taking the cross back. Bringing it to the choker on her neck, she attached it to the hanging chain. "I'll be sure to reward you next time."

Once the chain was attached to the cross once again, Moka-sama's body was enveloped in power. For those who could see, her voluptuous figure seemed to become that of a regular teenager instead of the young woman she was. Her features became softer and her eyes turned a jade green while her teeth became shorter. A rosy tint appeared on her skin while her hair changed to a valentine pink instead of the marble white it had been a moment ago. When the light died down, Moka looked like a completely different person before she wobbled on her feet and began to fall.

"I got you, Moka-san," Wataru whispered as he captured the girl in his arms. Hefting the girl up into a bridal carry, much to the jealousy of the other two teenagers, Wataru glanced back at his loved ones. "I think we have enough for a main article now. Let's get to it."

"YEAH!"

Headmaster's Office

From his position inside of his office, the headmaster of Youkai Academy witnessed the entire brawl from a view granted to him by a magic mirror in his possession. He was a middle-aged man who wore the robes of a priest, as expected since he was an exorcist. As such, he was perfect for the role of headmaster since in the most extreme cases, he could deal with any troublemakers in the school.

The man had to admit that the arrival of Wataru Kurenai and his friends were likely the best thing that had happened to his academy to date. Discipline was at an all-time high and it was without the fear and mistrust that the former Safety Commission had put together during their crooked reign. In fact, the boy's presence alone along with Moka's seemed to do that much without any effort.

Wataru was in truth half-human and half-Fangire, known as a Fandiri. Fangires were a powerful class of Youkai known as Mazoku. They usually resembled human/animal hybrids which looked like they were made of black flesh and stained glass. They thrived on human energy and for a while now, they had been causing their share of mischief in the human world. Of course, Wataru had been taking care of them as Kiva, which was a power granted to him by his bat-like Familiar, Kivat-Bat III. Despite his combat ability though, Wataru had been very shy and not very confident in himself regarding anything beyond his ability to play violin and how to craft the instruments. Still, that had changed in the past year.

Wataru had joined Youkai Academy as a freshman and from there had met Moka Akashiya on their first day. It was also how they discovered each other's secret power. Wataru had transformed into Kiva to protect her from an unruly student before he had discovered that by removing the rosario from Moka's neck unleashed her true power and nature as a vampire. Despite claims from other students who had their eye on Moka, the two actually made a good pair.

Kurumu Kurono had joined the school in hopes of finding her Destined One, a Succubus' mate of fate so to bolster the dwindling Succubus' population. Her initial plan had been to hypnotize all of the boys in school with her Charm ability so she could root out which one would be her mate. However, Wataru and Moka had derailed her little plan before it could get that far. In the aftermath though, Kurumu decided that Wataru was her Destined One and thus became a rival of Moka for his affections.

Next had been Yukari Sendou. Despite her age, she was a certifiable genius and had skipped several grades before entering Youkai Academy. She was consistently the number one student in the academic ratings and normally would have been popular with the other academic students. Being a border species of Youkai like a witch though, she was ostracized by her classmates and not very well-liked. To deal with her loneliness, she played pranks and tricks on everyone who was mean to her, earning her more dislike from the students. She had stumbled onto Wataru playing his violin and developed a crush on him, believing that she was the only one who would ever understand his talent at his art. So she entered into a prank war upon Moka and Kurumu for the sake of claiming Wataru. However, after both fandiri and vampire rescued the witch from some of the bullies, the witch somehow decided that she would begin a three-way relationship with the both of them.

Finally, Mizore began following Wataru after her return to school believing that she and Wataru were meant to be since they both knew what it was like to be alone. True to Yuki-onna courtship, she tried to freeze him in ice so she could whisk him away somewhere. Of course the plan didn't pan out as Wataru fought back, nearly breaking Mizore's fragile heart. Still, he managed to unwittingly win it when he rescued her from the former gym coach Kotsubo who had been harassing Mizore and plotted to have her expelled when she refused to let him take advantage of her. The beatdown he received was truly epic.

The headmaster couldn't help but snicker as he recalled the previous year. It was a whirlwind of fights and attempt at seduction which resulted in Wataru claiming his Fangire heritage in his Emperor Form to combat the former head of the Security Comission in a battle that students were still talking about. Despite being half-human, all of the students either adored him or tried to usurp his position as king of the school. None of them discriminated against him though.

"And that was just the first year," the headmaster grinned. "The second has already been shaping up into another eventful year. I do wonder what will happen next."

Kanto Region

Like a complete opposite to the withered lands surrounding Youkai Academy, Kanto held a bustling metropolis which was filled with people who went about their day. They were most certainly human and acted like it. Students went to school, adults went to work, and everything seemed to be the norm for a human city.

Appearances could be deceiving though.

The Kanto region was for a long time now trapped in a brutal gang war which was fought between seven schools. To the adult population and those who didn't know any better, it was a simple gang war fought between groups of thugs. For the people were knew better or were fighting in the war itself, the truth was much, much more compicated than anything a group of disgruntled students could think up of.

Each and ever participant in the war were known as Fighters. Likewise, each of them were host to a spirit from the Three Kingdoms era of China. Every Fighter possessed the spirit of a soldier who fought in the period, adopting their power and their destiny. It had been a destructive chain which had been in effect for 1800 years and had travelled over the ocean and into Japan. Up until the present, this chain of war, death, and rebirth continued on without much of a hitch.

But recently the mother of all monkey wrenches had been thrown into the planned fates of the Fighters.

Within one of the parks which were normally used by the Fighters to host their skirmishes, a new kind of battle was about to be fought. Stumbling out from one of the clearings was what appeared to be a mummy. It was wrapped haphazardly with aged white bandages, revealing gray flesh beneath. The only other identifying aspects it had were the red discs which were the size of large coins on its body and the sunken eye holes which were composed of slits.

The strange creature stumbled its way onto the scene which was normally inhabited by parents, couples, and children. Rather than simply terrorize people like some monsters were known to do in the history of the world, this one was making a beeline straight for the playground which had reached capacity this day.

"Toys…toys…toys…" the mummy…or rather Yummy rumbled as it approached.

It wasn't difficult for the people to notice. When a shambling corpse-like being starts coming towards you, people notice. Everyone in the immediate area began screaming and running away as they saw the monster approached. Mothers grabbed their children and ran while couples took their significant others and made for escapes. The Yummy didn't care though. Instead, it shambled onto the playground and dove into the sandbox where children had left their playthings behind. Dropping to its knees, the monster grabbed several plastic cars which had been left behind and raised them up to its face. From where the mouth would be on a normal human, a purple void opened up before the Yummy began dropping the cars into it, making a chewing noise despite how it wasn't moving its jaw. When all of the cars were swallowed, the Yummy just moved on to the plastic shovels and buckets which were in its reach.

As the Yummy continued to feast on the toys, the sounds of motorcycles sounded off as two black machines with rounded fronts appeared on the scene. On each one was a rider, one male and one female. Both of them wore similar tops consisting of a white button up shirt underneath a yellow sweater vest complete with a red tie for the male and a red bow for the female. The girl wore a red pleated skirt while the male wore dark pants. As their motorcycles stopped, both of them removed their helmets. What was most noticeable about the boy's uniform though was the red straps that were wrapped around his right arm.

The girl had long shoulder length golden hair and expressive green eyes. She was admittedly cute in her own sort of immature way, even if her figure was anything but immature, hence the nickname she earned at school, booby bombs. She looked on at the scene with a frown and when the wind blew slightly, a jade magatama was revealed hanging from her ear, indicative of the fact that she was one of the Fighters. Her name? Hakufu Sonsaku, the leader of Nanyo Academy and the one chosen to combat the Yummy and the ones who created them.

With her was a young man who had stylized blonde hair which was curled to the side, narrowed, spiteful eyes and a red magatama hanging from his ear. Anyone else who would have seen this boy would have assumed him to be Kokin Shuyu, Hakufu's cousin and her most dedicated protector. In truth though, the body was in possession of a creature known as a Greeed who went by the name of Ankh, the one who chose Hakufu to be the one who battled Yummies for him.

"Man," Hakufu frowned as she eyed the Yummy eating toys. "Is that Uva-chan's Yummy? He's been causing a lot of trouble lately."

"He never was the patient type," Ankh shrugged. "Better for us though since it means more Cell Medals for me." Raising his right arm, Ankh's limb from the elbow down was covered in silver coins which had an X on one side and an animal etching on the other. The coins had a red aura over them as they pooled over his flesh. Once every inch was covered, the coins fused together to become a strange arm covered in red and green flesh with what appeared to be small feathered wings coming out of the forearm. The fingers looked almost like bird talons with rings adorning them. This in truth was Ankh's true form in its entirety.

"Let's take it down Ankh-chan!" Hakufu grinned, producing a rectangular box-like object with three slots in it and coloured black with blue lines on it. Hopping off of her motorcycle, she attached the item to her waist which produced a silver belt that secured itself to her. On the left side, a roll of silver coins like the kind which made Ankh's arm appeared. On the right was a round disk-like object which was gold and had a void on one half of the centre to act like a handle.

"Just get those Cell Medals and I won't complain," Ankh shrugged. Flicking his kaijin wrist, he produced three more coins, but these ones were quite different. All three had gold rims while they were coloured with an animal marking in the centre. The first was red with a hawk marking, the second was yellow with a tiger marking, and the last was green with a grasshopper marking. Almost carelessly, he tossed the coins to Hakufu who grabbed them eagerly. Stepping away from the bike, she slotted the coins into her belt right, centre, and left to correspond to red, yellow and, green. Finally, she turned the buckle diagonally, making it start a pulsing noise. Preparations complete, she took the disk object known as the O-Scanner and swiped it across the buckle with three chiming noises.

"Henshin!" she commanded.

"TAKA!"

"TORA!"

"BATTA!"

"TA-TO-BA TATOBA TA-TO-BA!"

Hakufu was suddenly surrounded by colourful coins which circled horizontally around her head and torso while a third ring hovered vertically over her head and through her chest. In front of her, large holographic images of the coins she used appeared in a vertical line in front of her with Taka at the top, Tora in the middle, and Batta on the bottom. The three images then fused together to create a larger coin with the three images implanted within. Again, the Taka was at the top, the Tora filled the middle, and the Batta filled the bottom.

The combined crest flew backwards and collided against Hakufu's chest, covering her in a new suit of armour. For the most part, it was black, but each section was covered in a different coloured suit of armour which corresponded to one of the three sections of the crest on her front. The legs were covered with green segmented armour on the front which were similar to that of a grasshopper, connected by green lines to the Batta section on her chest. The torso armour had round shoulder pads which had a yellow rim while the gauntlets were completely yellow with claw-like additions on them. Finally, her faceplate was styled after a hawk in flight and coloured red with a gem acting as the beak on her forehead. She was able to see through the large green eyes which the helmet sported which completed her looks.

Hakufu had gone beyond a simple Fighter, she had become Kamen Rider OOO!

The Yummy was clearly not impressed as it ignored OOO in favour of gulping down a stuffed bear. As the last of the plush toy vanished into its mouth, the kaijin gave off a groan before standing up. It's skin began to crack and peel as dark flames seeped through the space. Inhaling deeply, the monster gave off a fierce cry before its entire body crumbled and cracked, falling off in one large blast of dark flame. Rather than die though, the creature had shed its skin and developed into a completely new form.

The Yummy's new body was a dark bronze colour. It's torso still looked humanoid, but segmented into different sections. It's shoulders were dotted with spindly legs not unlike a centipede's would be. In the centre of its chest was a red disc while around its waist was a black strip of leather decorated with small chains and a second red disc acting as a buckle. Its arms looked like two oversized centipedes growing from its shoulder blades with its hands, bronze and segmented, sticking out from underneath the mandibles. It's legs were covered in a dark brown armour which had even more centipede legs coming from the sides and mandibles sticking from the feet. Finally, it's face seemed like an orange porcelain mask, but with a centipede-like turban wrapped around it to the point that the eyes were obscured. The regular White Yummy had transformed into a Centipede Yummy.

If anything, Ankh seemed pleased by the transformation, "Right on time." He then glanced at OOO. "Well? What are you waiting for? Go get him!"

"Right!" OOO agreed before she leapt into the fray.

Kougami Foundation

Watching through a combination of his company's Takacan and Battacan was Kousei Kougami. He was a middle-aged gentleman who was the owner and founder of the Kougami Foundation. His company was the ones who studied creatures like the Yummies and created equipment needed to fight them. Kougami himself wore a red suit and while he was watching the battle between OOO and the Centipede Yummy, he was actually in the process of making a birthday cake. The reason for this was that Kougami was a man who believed that for good or for ill, a birth was something to be celebrated and thus went to do just that at every opportunity.

Kougami had decided to support Hakufu's exploits as OOO in return for a portion of the rewards that came from defeating Yummies. He supplied her with equipment and information whenever she needed it and in return she gave him Cell Medals which made up the bodies of the Yummies. It was an excellent deal if he thought so himself. The birth of their alliance would help both of them grow stronger in order to defeat the Greeed.

But what are the Greeed you ask?

The Greeed were homunculi created 800 years ago using the essence of animals and Cell Medals to create them. Each one of them was based off a different type of creature. Uva the Greeed of insects, Gameru the Greeed of Mammals, Mezul the Greeed of fish, Cazali the Greeed of felines, and Ankh the Greeed of birds. They had been defeated by the previous OOO and sealed away. However, they had recently freed themselves and were loose in Kanto, mingling with the people and going up against the Fighters. Strangely, when Ankh was freed, he only had enough power to manifest himself as his own right arm. To make up for this, he had possessed Kokin Shuyu who had been grievously injured by a Bear Yummy. He was also the one to give Hakufu the O-Driver so she could become OOO in the first place and defeat the other Greeed.

Kougami was in fact responsible in a way for the Greeed being loose in Kanto. He had placed their tomb in one of his museums for safe keeping. It had been a precaution since the Fighters in Kanto, reincarnated warriors from China's Three Kingdoms era, were in the midst of their re-enactment of the Three Kingdoms war. The Fighters battled with all of their power to forge their kingdoms and achieve their destinies. They did destroy in their pursuits, but all they did was to achieve a desire to create. Kougami felt that they were a perfect counter to the Greeed's desire to destroy. In fact, it seemed his hunch was right as Hakufu was not only a Fighter, but also the reborn leader of the Wu Kingdom from 1800 years ago. A perfect user!

"And so the desire of the Fighters clash with the desire of the Greeed," Kougami pondered as he eyed the fight on his monitor. A silly grin overtook his face. "SUBARASHI!"

Kanto Park

OOO and the Centipede Yummy clashed with one another as they struggled in their battle. OOO had drawn a black sword which had blue lines, a slot and handle near the hilt, and what appeared to be a small window inside the blade itself. It was a weapon supplied by Kougami known as the Medajalibur, and it was just one of the many weapons that OOO had at her disposal.

OOO swiped wildly at the Yummy, but the kaijin was proving itself flexible as it managed to bend in every direction to dodge the assaults. Its body was proving extremely flexible as it dipped and curved to avoid the sword strikes. It had yet to make a counter-attack, which to a normal Fighter would have been worrisome, to OOO however…

"Quit moving around and let me hit you!" the armoured Fighter whined, slashing even more with her weapon.

The Centipede Yummy didn't answer, but it did leap backwards. Rearing back its arms, it launched them forward to attack. To OOO' shock, the arms stretched! The centipede-like arms cut across the open space between the two before colliding with OOO' chest. The hard impact made her cry out as she was sent stumbling backwards. Grunting, she stumbled back to her feet, but only had a moment to blink before the stretching arms flew at her once again.

"Woah!" the Rider cried as she rolled to the side. Again, she only had time to blink before the stretching arm flew at her a second time. Rolling once more to dodge the attack, she swung blindly at the arm, hoping to at least wound the creature. Her aim was true as the blade dug into the hide of the Yummy's arm, but rather than open a wound the skin just stretched. The Centipede Yummt quickly retaliated and with a twist of its arm, knocked OOO away once again.

"Oof!" the Little Conquerer cried as she hit the dirt. "Man, this one's hard to fight."

"Oi!" Ankh's voice barked out, causing OOO to turn to her possessed cousin. "Quit fooling around and kill the thing already!"

"I'm trying!" OOO snapped back. "But it's just so stretchy!" The Kamen Rider looked back at the approaching Yummy whose arms were hanging in the air, ready to go for another assault. At first it looked rather intimidating and for a regular person it would have been. However, when OOO looked on at the Yummy, she was suddenly struck by the human ability to recall something which seeming had nothing to do with the situation at hand. An idea which seemed so random, most people would have discarded it as a momentary insanity or just a goof-up. It was otherwise known as a brain fart. Most would just disregard it and try to follow logical thought processes, OOO on the other hand thought of it as an epiphany. "Oh! I got an idea!"

"You do?" Ankh frowned, eyeing his partner. "First time for everything I suppose."

"Hey, it's a good one!" OOO insisted as she got to her feet, eyeing the approaching Centipede Yummy. "I saw it in a manga once!"

"That doesn't fill me with confidence," Ankh sweatdropped.

"Just watch me!" The immature Fighter grumbled as she began her charge. Gripping her weapon, she placed her hand at the top with the blade facing away from her. The Centipede Yummy wasn't intimidated as it lashed out with its left arm, letting it stretch towards for another strike. OOO just continued her charge, but this time her eyes weren't on the Yummy's body, but eyeing its arm. The eyes of her helmet flashed and turned red, activating the inherent power of the Taka Medal and allowing her to precisely target the area she was looking for; The Yummy's elbow joint! Spotting the area in question, OOO charged forward with her blade positioned for the blow. Coming underneath the stretching arm, she suddenly jumped up with the blade pointing up. The Batta Medal powering her legs allowed her to jump higher than any human being, letting her rise high into the air with the Centipede Yummy's stretchable arm caught on the edge of the Medajilabur. The blade of course didn't cut the kaijin's skin, but it did stretch it to a ridiculous thinness that no living species could compete with.

"What is she-?" Ankh frowned.

"Stretch," OOO grinned, gripping her blade. "Then twist!" She then spun the sword rapidly in her hands, wrapping the Centipede's already stretched limb around the blade, stretching it further until…

SNAP!

"RAAAAAAAAAAAAAAAAAAAAAHHHH!"

The Centipede Yummy roared as it drew back it's arm…what was left of it. The limb had been severed at the elbow, the stump spilling out silver coins which had animal markings etched on one side with an X on the other, Cell Medals. OOO landed on the ground, feeling smug as a few Cell Medals spilled over her and bounced off of her armour. Behind her, the rest of the Yummy's arm landed with a meaty thud. When it came to rest, the entire limb began to dissolve and collapsed into a pile of Cell Medals. OOO giggled to herself before pointing over at Ankh, "Take that Ankh-chan! I knew it would work!"

"Whatever," the bird Greeed huffed. "Just beat the thing already."

"Ugh! No respect!" OOO huffed childishly before she scooped up three Cell Medals from the ground. Taking them, she slotted them into the handle of her sword which made chiming noises in response. She then pushed the handle next to the slot, dropping the Medals into the blade itself. With the Centipide Yummy writhing over the loss of its arm, she used the distraction to use her next attack. Taking the O-Scanner from her hip, OOO swiped it across the three Medals in the small window of her blade, creating three chiming noise.

"TRIPLE SCANNING CHARGE!"

"Hooooooooooooh," OOO breathed, bringing the blade back as it began to glow. Keeping her target in sight, she slashed into the open space between them. "HIYAH!"

A lash of energy cut through the air, creating a line of light through both the Yummy and the scenery behind it. Were anyone watching, they would have gaped in shock as not only the Yummy's body higher than the cut began to slide on an angle of the strike, but so did all of the scenery as if the world itself had been cut. The bisected scene lasted only for a moment before resetting itself, but the Yummy remained cut before its entire body exploded in a fireball, sending Cell Medals flying in all directions.

"All right!" OOO cheered, happy for her victory. "Another one bites the dust!"

"Whatever," Ankh sighed, dismounting his bike. "Just get out of the way so I can collect my Medals."

"Oh come on Ankh-chan! You have to admit that was cool!" OOO whined.

As the pair began to go off into another one of their arguments, they did not know that they were being watched. Sitting inside of a blue compact car was a man who wore a simple black lab coat and plain clothes. His face was stoic and he wore glasses over his eyes. What was odd however was the fact that he had a small bald doll in a white suit sitting in a safety chair made just for it beside him. His name was Dr. Maki and he had been the one who had invented the Cell Medal machines which OOO used.

"Field test, successful," he muttered. "A most satisfactory conclusion."

Youkai Academy-Headmaster's Office

"Too many."

The words echoed through the dark office which the Headmaster called his own within his school. He was seated at his desk, but the usual sinister smirk on his face had been replaced with a concerned frown. Spread over his desk were pictures of what appeared to be animal-like monsters fighting humans and a multi-coloured warrior. Notes attached to the pictures had them revealed as to having come from Kanto.

"Too many sightings of Youkai in the area," the Headmaster frowned. "All of them causing chaos and attacking humans in the open. It's like they don't even care about keeping our world secret from humans."

That just wouldn't do. As one of the three Hell Lords, it was the Headmaster's responsibility to help ensure that the balance and peace between humans and Youkai was preserved. These latest incursions were almost like a challenge to that authority. If it continued, it could possibly reveal the secret of Youkai to the entire country if not the world. Should that happen, any peace which both sides had claimed for themselves would be gone like a candle in the wind. That could not be permitted.

"It still begs the question: How to deal with it?" The Headmaster pondered. He had a host of agents to assist him in such matters, but the level of power that these strange Youkai revealed made it obvious they would be unable to do anything beyond annoy the beasts. Some of the school's alumni may have been able to deal with it, but they were all in posts and positions that prevented them from going at to Kanto to deal with it. The situation in that area was volatile already with the spiritual power that flooded that area. No, it seemed that the only course of action he had until he had more information was…

Youkai Academy—Class 2A

"Guess what everyone! We're going on a field trip!"

The classroom erupted in cheers as the always cheery and sometimes ditzy teacher Ms. Nekonome announced the sudden news. The woman was in fact very attractive and showed it off since she always wore skirts and tank tops which revealed how womanly she was. She had perfectly styled hair and wore small rectangular glasses which were in truth very cute. Of course, she was a Youkai but everyone knew she was a cat woman since her feline ears stuck out on top of her head and her tail was sticking out from under her skirt. She was a very nice woman and certainly gave her all when it came to teacher her students. Of course, it still didn't take away from the fact that she was kind of ditzy sometimes.

Her announcement had brought eruptions of cheers from her class as it would from any high school group. All of them had felt cooped up sometimes since the only source of entertainment and excitement that Youkai Academy had was the nearby small town and even that got boring after a while. Hearing that they were going somewhere, anywhere was a cause for celebration.

"As a special treat from the headmaster, we're all going on a special trip to the human world!" Ms. Nekonome continued. "The entire second year is going to enjoy a week of learning and culture in the Kanto area! Doesn't that sound fun?"

"YEAH!"

Ms. Nekonome went on to explain some of the particulars about the trip, but faced with such good news not all of the students were paying that much attention. Many of the students were whispering excitedly to one another about what they would see and do on the trip. Among those students were five of the most well-known of the group: The King and Queen of Youkai Academy, The Sexy and Alluring Sempai, The Cute Little Genius Sempai, and The Mysterious and Aloof Sempai.

Moka sat in her chair smiling as she thought of Kanto and what activities that she and Wataru could be doing while there. She could already imagine the bright lights and popular attractions which she and the man she loved could enjoy. She could picture herself in something stylish while Wataru would look cool in just about anything. They would enjoy all of the sights, watch the latest movies, by some amazing souvenirs…and at the end of the night, share a loving kiss under the moon.

-Sigh-

Kurumu giggled to herself as she already began plotting her latest scheme for getting Wataru and herself to become more intimate. She could already think of all the shopping that would be available in Kanto, and that meant the latest styles of fashion. She would take Wataru with her to the biggest and most stylish place in town and begin her own modelling show for him. Of course, it ould only be her showing off her outfits and nobody else. Then, when they were alone in the privacy of a hotel she would show him how to take those outfits off of her body.

-Giggle-

Mizore drifted off into a daydream of herself and Wataru visiting one of the many beautiful shrines which Kanto had. The peace and serenity would be perfect for having Wataru become more comfortable. They would tour some of the gardens and statues of the shrines and feel all of the calm that they would exhude. And then in the privacy inside one such shrine…they would become husband and wife in the most primal way possible with the blessing of the gods.

-Jiiiiiiii-

Yukari grinned mischievously as she plotted her next plan within her genius mind. She knew that the school was likely going to book a large hotel or at least a big modern one so that everyone would have a space to sleep in. To that end, she would just need to make sure that Moka and Wataru were close to one another. So when their natural urges got the better of them and they went to satisfy them, she would 'accidentally' walk in stating she had a bad dream and wanted to snuggle. And then…her threesome would finally happen!

-Drool-

Wataru shivered at his desk and felt like someone had just steamrolled over his grave. Looking around, he didn't see anything out of place. That just made him wonder who had been talking about him.

Youkai Academy-Class 3A

"Kanto, eh?"

Sitting on the third year classroom were a trio of students who were the sempai of the most popular students in the room. The first was a young man with brown hair who bore a slight resemblance to Wataru. However, he exuded much more confidence than Wataru did and even while reclining in his seat he gave off an air of nobility. Despite wearing the same uniform as his classmates, he still came off as someone you should instinctively defer to. His name was Taiga Nobori and he was in truth Kamen Rider Saga, the Fangire King. He had at first come to Youkai Academy in order to get some normalcy in his life after being trained to be King for as long as he could remember. He had met Wataru there and rekindled their old friendship which they had made as children. However, Saga was determined to kill Kiva for being a threat to the Fangire Clan. As time went on though, Taiga learned that not only was Kiva his old friend but many of the Fangire Clan had been going on rampages and threatening the secrecy of the world of youkai behind his back. Worse yet, they had been encouraged to do that by his advisor Bishop who wanted to spark off a war between humans youkai, convinced that it would be an easy win for their side. So by working with Wataru, his half-brother and their friends they fought to ensure that the peace continued.

"That sounds fun!"

Sitting in the desk next to Taiga was a girl that for all intents and purposes, seemed rather plain. She was cute, with shoulder length dark hair but there didn't seem to be anything about her that screamed unique or extraordinary like many of the other girls of Youkai Academy. However, it went without saying that nothing was as it seemed in their school. Her name was Mio Suzuki and she was in fact a Fangire, the Queen of the Fangires in fact. Mio for a long time though she was a regular girl. Being orphaned at a young age she had no idea about her origins and thus lived her life as a human. However, her true nature came to light when Taiga's traitorous advisor Bishop forcibly awakened her powers as Queen and attempted to use her to turn Taiga into his puppet. Fortunately, Taiga and Wataru managed to rescue her.

"Sounds like a good article for the next paper."

Behind the pair was a fellow third-year student. He was in fact a handsome specimen with black hair held back with a red hairband. He didn't wear the school tie and left the shirt unbuttoned to let some of his pecs be revealed. He wore a silver wolf-shaped amulet and was lounging at his desk while the teacher droned on about the responsibilities select third-years would have on the upcoming school trip. His name? Ginei Morioka, president of the Youkai Academy Newspaper Club. Gin was in truth a werewolf and in fact a rather perverted one. In the previous year, he had gained infamy as a peeping tom as he peeked on girls changing for their gym classes or in their rooms. His speed allowed him to get away before anyone could recognize him. To take the heat off, he attempted to frame Wataru as the peeper which would in turn allow Gin to swoop in and take Moka for himself. His plan fell through though when Moka refused to believe the evidence while Kurumu and Yukari managed to dig up the truth. Wataru himself kicked Gin's ass in a brawl when the werewolf had tried to take Moka by force. Everyone had moved on from the encounter, but none of them really trusted Gin when it came to girls afterwards.

"Now, for the upcoming trip to the Human world region of Kanto, select third year students with good behaviour records will be selected to act as aides for the teachers who will be chaperoning the trip," the teacher, Ms. Kagome explained to her class. For once, everyone was paying attention to what she was saying rather than what she looked like as the epitome of sexy intelligent teacher. "As such, those selected students will be given free passes on any work they may miss while chaperoning on the trip." She took a moment to wait for the resulting cheer to die down. "If you wish to apply for a chaperone role, please leave a one sheet piece of paper with your name and reason why you should be selected on my desk before class ends. Understand?"

"HAI!"

"Good," she nodded before turning back to the board. "Now picking up where we left off last class…"

Kanto—Nanyo Academy

"Mnnnnn!" Hakufu yawned with a stretch as she and Ankh stepped onto the grounds of their school for another day of learning and leading the fight against the Greeed. Unfortunately, neither Ankh nor Hakufu really wanted to be there. "Man, why does school have to start so early? I'm still tired after fighting that Yummy yesterday."

"Oh suck it up," Ankh sighed. "If I have to sit through this torture then you do too!"

"But Ankh-cha~an!"

"You know, whining about it isn't going to make it easier," a new stoic, female voice spoke up. It served to catch the attention of the pair as they turned to see who was talking to them.

She was a fellow student of Nanyo and wore the same uniform that Hakufu was, with slight alterations. She wore blue socks with black heavy boots and blue gloves over her hands. She had short blue hair which only slightly reached past her ears. On one of those ears was a silver magatama, indicating her status as a Fighter. She had blue eyes, but only one could be seen since her left eye was covered by a white eyepatch. On the left side of her mouth was a beauty mark as well, enhancing her already attractive face. She was as expected of the girls of Nanyp, a curvy specimen but she was a Fighter to the core and was more likely to kick your ass if you flirted with her than anything else. Her name was Ryoumou Shinmei and she was not only a lieutenant to Hakufu as one of the Big Four of Nanyo, but she was arguably the blonde's best friend too.

"Hi Mou-chan!" Hakufu waved to her bluenette friend. "What's up?"

"Not much, which is more than I can say for you," Ryomou replied, walking up to her leader. "Word about your fight in the park spread around. You aren't really all that subtle are you?"

"It wasn't my fault!" Hakufu whined. "The Yummy decided to go there on its own! I just followed Ankh-chan and went to fight it!"

"And managed to make a spectacle of things as always," Ryomou retorted. "I get that the Yummies have to be taken down and fast, but if we cause too much of a problem fighting them then the wrongs kinds of people are going to start asking questions. Frankly I'm surprised that the army hasn't gotten involved."

"As if it would make a difference against the Greeed," Ankh snorted. "I've seen what your guns can do and at worst they'd just slow us down."

Ryomou sent a glare at Ankh, but he easily ignored it. He'd been glared at by worse than one teenage human girl. The blunette could tell that her game face wasn't going to help her either. So she decided to just move on in the conversation, "So what kind of Yummy was it this time?"

"A Centipede Yummy with really stretchy arms!" Hakufu grinned. "It was gulping down toys that little kids were playing with and it was really hard to beat since it wouldn't stand still. Uva-chan's really been busy lately. He must really want his Core Medals back."

"Obviously," Ryomou nodded. Still, something was bothering her when she heard it was a Centipede Yummy that went on the attack. Normally she wouldn't have cared much beyond that, but she had heard something recently when coupled with what she just heard made her think twice about the Yummy and what may have created it. "Ankh, about Uva's Yummies. Are they strictly insects or do they involve any kind of creature we call a bug like spiders or scorpions?"

"Huh?" Ankh frowned. "What do you mean 'does he use insects'? Of course he uses insects! I think that would be painfully obvious by this point! What could make you think otherwise?"

"Because centipedes aren't insects," Ryomou replied.

"Huh?" Hakufu blinked.

"Honestly, didn't you pay attention to class?" Ryoumou sighed at her leader's ignorance before she continued. "Centipedes are arthropods like insects, but they're from a different family of them altogether. Aside from having segmented legs and armoured bodies, they're nothing like insects at all. All of the Yummies we know Uva made are based of things which we know are insects. Three body sections, six legs. Centipedes don't follow that trait. That is why I'm asking if Uva sticks to just insects or if he can also make Yummies based off insect-like creatures."

"Wow, we learned all that in class yesterday?" asked Hakufu in amazement. "I guess I shouldn't sleep through class so much then."

Ankh frowned slightly at the explanation and pondered the implications. After a moment of recalling everything he knew about Uva, he spoke again, "I've never seen Uva make Yummies based off spiders or other things like that before. I assume he could, but all of the other Yummies I've seen him make stick to things I know are insects," he scoffed. "You sure like making things complicated, don't you?"

"Better than being caught by surprise, isn't it?" the bluenette retorted.

"Hmph!"

"Man, this is getting exciting," Hakufu grinned. "This might mean a new enemy to fight!"

"Battle junkie," Ankh muttered.

"Hey!"

Youkai Academy

Some time had passed and finally it was time for the second-year trip to the Kanto area. Busses were lined up outside of the school as the second-years, the teachers, and the third-year chaperones all waited as attendance was taken to make sure no one was left behind.

"I'm glad you could come with us Nii-san," Wataru smiled as he and Taiga waited for their friends to show up.

"Like I would miss something like this?" asked Taiga with a grin. "A trip like this doesn't happen often and I for one do not plan on missing out."

"Wataru!"

Wataru suddenly felt himself get glomped by his succubus lover as she pressed her chest against the side of his head once again. He had gotten used to such things, but it was still a little embarrassing to have happen in front of others. It didn't help that a lot of the boys would grumble with jealousy at seeing one of the bustiest girls in the school pay attention to him rather than any of them.

"Oooh, I'm so excited!" Kurumu beamed. "Would it be alright if I sat next to you? You can rest your head on my lap if you feel tired."

"Uh…" Wataru blushed. He may have been intimate with Kurumu, but he was quite at her level of proclaiming how close he was to his lovers like she was.

"Wa-Ta-Ru…"

Wataru felt his arm get tugged and he was free of Kurumu's cleavage, finding Mizore attached to his arm, smiling up at him, "Wouldn't you rather sit next to me during the ride? We can…snuggle."

"Hey! I got here first stalker!" Kurumu huffed.

"It's Wataru's choice," Mizore retorted. "You'll pick me, right?"

"Ano…"Wataru gulped.

KLONG!

HSSSSS!

Both girls suddenly vacated his arms when Kurumu was hit in the head with a brass pan while a kettle filled with hot water began to chase Mizore around in attempts to pour the contents on her. Slipping through the crowds came the familiar form of Yukari as she had he wand held into the air, the glow of magic fading from the heart-shaped tip. She came up to Wataru and promptly hugged him around the waist.

"Must you two be so lewd?" she huffed. "Only Moka-sama is worthy enough to sit next to Wataru-sama," her face then turned into a parody of sultriness, making Wataru feel very uncomfortable. "With me in his lap. Fufufufu!"

"Uh…" Wataru gulped, now looking for a means of escape from the perverted little girl.

"Your luck with the women astounds me," Taiga chuckled. "You must get it from your father."

"Wataru-kun!"

Wataru looked up and saw the crowds of boys parting with praises to the person they were moving for. Unsurprisingly, it was Moka that they were moving for. Hailed as one of the school beauties, but she didn't seem to notice what they were saying about her. Instead, her focus was aimed more at Wataru. Yukari quickly moved out of the way, not wanting to interrupt a moment between 'her two future lovers'.

"Moka-san," Wataru murmured.

"Wataru-kun."

"Moka-san."

Moka-trembled in delight as she got closer to the man she loved. Once she got close enough, she lunged for what looked like a passionate hug, the kind which would no doubt lead to a hot kiss. Indeed, Moka and Wataru hugged, but after that…

CAPU-CHU!

She bit into his neck.

"Ow!" Wataru grimaced, feeling Moka drain his blood yet again.

"Ah!" Moka sighed, taking her fill. "Delicious as always! Now I'm ready for the trip!"

"That's…good, Moka-san," Wataru grimaced, holding his neck. Behind him, both Kurumu and Mizore frowned at seeing the love of their lives being made into a snack by the pink-haired vampire yet again.

"All right!" the voice of Ms. Nekonome cheered, halting any chaos before it began. Next to her was a man in a bus driver uniform who was idly smoking a cigar. The bring of his hat covered his eyes in shadow, but his eyes were glowing a strange yellow colour. "Attendance is complete! Everyone please board your assigned busses please!"

"And remember," the driver spoke up. "Kanto is a very mysterious place. Watch yourselves."

"HAI!"

Kanto

Walking down the street for another day at Nanyo, Hakufu stopped as a strange look came over her face. Frowning, Ankh turned to glare at her, "What is it?"

"It feels like something important is going to happen," the blonde girl frowned. "I wonder why."

"You and your imagination," Ankh scoffed. "Now let's go! I don't want to give your crazy mother more reasons to get on my case."

"Right!"

To Be Continued…
