A/N: Welcome, minions...Just kidding. Thanks for deciding to click on this thing. This is my first attempt at a crossover, with Kamen Rider Wizard and Trinity Seven, because...magic.

This is gonna be sort of a pet project for when I'm stuck for my main story. Those who read it, you'll know. Those who don't, check out my profile if you're interested.

I just wanna make it clear that I'm pretty much cribbing the entirety of Trinity Seven's story, with some original portions for the Rider battles, but some stuff is modified, so skip at your own risk.

And since I'm cribbing the storyline, I'll have to put this disclaimer below, I guess.

Disclaimer: I don't own Trinity Seven nor any of its characters (I'd like to though). I also don't own Kamen Rider Wizard or any related property. Except for my toys. Those are mine.

Chapter 1: End of the World and Wizard

"Don't ever forget about me, alright?"

Darkness.

He felt suffocating pressure all around him, yet his eyes, wide open, saw nothing.

A faint glow drew his attention, his vision blurring from the break in the gloom.

Who-?

A figure floated before him, a mere silhouette cast against the light.

I…I have to get to her!

He reached his hand to the figure, yet it seemed as though distance itself was stretched between them.

She's so close, I have to-! He stretched further and his fingertips neared the figure. At the same time, the silhouette reached out for him as well.

A little more…

As their fingertips were about to connect…

*Boing*

His hand registered elasticity and softness, under a soft fabric.

Kasuga Arata opened his bleary eyes. Following his outstretched arm upwards, he found his hand firmly gripping onto…a breast.

A girl with short light blue hair frowned at Arata, her face glowing in embarrassment. She was dressed in a white sailor fuku, with a red ribbon, and a black skirt.

"Oh, Hijiri…" Arata sat up on his bed. "Good morning. Breakfast?" He gave a grin.

"Don't you 'Breakfast?' me!" Kasuga Hijiri shouted. A loud slap rang through the apartment that was the Kasuga residence.

Arata stared at his cousin's pouting face across the table, a red hand mark still throbbing on his cheek.

"Come on, you're still mad?" he mumbled through another mouthful of rice.

"Don't you have something to say?" Hijiri replied.

Arata put down his chopsticks and crossed his arms in thought. Then, he snapped his fingers, as if he came upon a brilliant answer.

"You've gotten bigger," he answered in a self-satisfied manner, with a thumbs-up and a huge smile on his face.

"That's not what I meant!" Hijiri shouted.

"Why? Bigger is good," Arata asked as he got back to his meal.

"That's not the problem here!" Hijiri retorted.

Arata let out a sigh. The two ate in silence for a few seconds.

"Look at that," he suddenly said, pointing to the wall to his left with his chopsticks.

On the wall was a crayon drawing of two people under a tree and a red sun in the sky. Scrawled on a blank spot in black crayon were the words 'I love Onii-chan'.

"You were such a sweet little girl back then, following me around going 'Onii-chan'. What happened to that girl?" Arata lamented.

"Why did you keep such an embarrassing picture? And you even put it on display!" Hijiri flailed her arms around, then rushed to tear the drawing off the wall.

Arata sniggered. "You're too late. I've already made it my phone wallpaper long ago!" He dramatically brandished the device in his cousin's face.

Hijiri gave a shriek and tried to grab Arata's phone. Casually turning around to avoid her, he grabbed his bag and black blazer and rushed out the door, Hijiri close behind.

"Hold on, time out!" he shouted while buttoning the blazer over his white shirt. Seeing his cousin continue to approach with a vindictive aura, Arata fled down the corridor.

Hijiri caught up with him soon enough, however, but he was let off with a light slap on the arm.

"Let's go, then," Arata grinned.

The duo made their way down their usual route to their high school, chatting casually along the way.

Well, uneventful days like this are nice. As Arata thought that, he looked up at the sky and felt a dissonance resound in his brain.

The sun, which he remembered from childhood to be a bright ball of heat and white light, was now completely black.

And not just simply black. The sun seemed to not only be dyed the color, but also exude a black miasma.

Beside him, Hijiri took a deep breath. "Isn't the weather great? I'm glad it's sunny out today."

"But hold on…" Arata began to say.

"Hm? What's wrong, Arata-san?"

"…Nothing. Must be my imagination," Arata shrugged.

As the duo continued on their way, Arata noticed a girl approaching them. The girl looked about the same age as him, with long, flowing pinkish-red hair. A lock on her right side was braided and hung in front of her right shoulder.

A student from our school? Never seen her before. Arata noted her uniform, which was the same as Hijiri's

Even if I don't remember her face, Arata looked down to her impressive bust. I would remember those boobs.

As the mysterious girl passed Arata, he heard her murmur something into his ear.

"Hurry up and awaken, Kasuga Arata. If you don't, I will have to kill you."

Arata felt a jolt through his body and he turned around, only to see an empty street.

What the heck?

Throughout the morning's lessons, Arata couldn't pay attention, finding himself staring at the ominous-looking black sun.

It doesn't even hurt to stare at it…What kind of freaky situation is this? Arata was beginning to doubt his own sanity.

And then there's that thing…

"Hurry up and awaken, Kasuga Arata."

What's she on about? What do I need to wake up from?

Arata was so wrapped up in his thoughts, he failed to notice the bell for lunch.

"Hey, Kasuga!" one of Arata's classmates called to him. Looking up, he saw Hijiri standing at the door.

"Your wife's here with lunch!" his classmate said with a grin.

"W-W-W-Wife?!" Hijiri's face flushed ruby red for the third time today.

"Can it, Arakawa. Quit teasing my cute little cousin," Arata casually cuffed his classmate's shoulder.

"Let's go," Arata said to Hijiri, closing the door on his classmates' cheers and wolf-whistles.

The two made their way to the rooftop, where Arata plopped himself onto his usual spot against the wall.

He stared up at the black sun again for a minute, then Hijiri stood in front of him, blocking his view.

"What's wrong, Arata-san?" Hijiri asked.

"Say, Hijiri," Arata began. "Was the sun always black?"

"…What are you talking about, Arata-san? The sun was always black, since before you were born to even after you die," Hijiri replied, smiling.

"Seriously?" Arata grinned back.

"Yeah. This is the kind of world you live in, and the exact world you wished for," Hijiri said, now bending down closer to his face.

"The world I wished for?" Arata was confused.

"Yes. A world where I'm here with you, and we enjoy our everyday life," Hijiri's tone took a dark edge as she lowered herself and sat on Arata's lap.

"So…" Hijiri's face was dusted with pink, and her eyes glinted dangerously. "It doesn't matter if the sun is black, does it?"

"In this world," Hijiri's fingers brushed against Arata's lips, then along her body. "Your very own Hijiri will do whatever you want. So, Arata-san…" Her fingers gripped the ends of her red ribbon and pulled.

Arata gulped at his cousin's boldness, but a sharp sting shot through the back of his head.

"Don't ever forget about me, alright?"

"Ah!" Arata's hand snapped to his head, gripping it to quell the pain.

"What's wrong?" Hijiri stopped her unravelling and got off Arata.

"…Are you really Hijiri?" Arata glared at the blue-haired girl in front of him.

The girl's ruby red eyes widened.

"Wh-What are you saying? Of course I am!" the girl said, standing up.

"I'm Kasuga Hijiri! Your cousin and childhood friend!" she continued with a little spin.

"…When's my birthday?" Arata narrowed his eyes.

"June 18th."

"What's my favorite food?"

"Fried chicken."

"Where do I hide my porn magazines?"

"Under a tile under your bed…Do you still not believe me? You know I won't lie to you!"

"…What color is the sun?"

"Of course it's black!"

"Wrong answer," Arata got up. He pulled out his phone. "If the sun was always black," He showed his wallpaper. "Then why did you draw the sun as red when we were little?"

The girl let out a small gasp.

"Hijiri's always been as honest as can be. She even told me off for coloring the sky indigo and not bright blue back then. So why would the picture not match the color of the sun? Exactly who are you?"

'Hijiri' lowered her gaze for a moment, then threw back her head in peals of laughter.

"Oh man, you got me there. Aren't you a little too observant? Trust you to figure it out from the drawing of a five-year-old," 'Hijiri' smirked, her voice changing to a mocking one.

A loud bang sounded from behind Arata, then a blue light shot towards 'Hijiri'. The light made contact, but the girl's body disintegrated into shadowy bits, then reformed.

"Hey, hey. Isn't that kind of a rude greeting, you mage?" 'Hijiri' said to someone above Arata. He turned around and saw a familiar girl.

"You finally showed yourself, cracker!" she shouted at 'Hijiri'.

"You're…that girl with outrageously huge boobs!" Arata shouted.

Standing on top of the water tank was the mysterious girl from that morning, but she was now dressed in a white sleeveless collared shirt, with a red tie, and a black miniskirt with black thigh-high socks. A black beret with a small red bow secured with a ruby sat on her head. In her hands was a huge rifle, the length easily surpassing her height. On her nose sat spectacles with a red lens, with the left side missing. Around her waist, a brown leather belt elf up her skirt, but the metal buckle was in the shape of an open hand, traced in gold and the fingers pointing down to the left.

Hearing Arata's cry, the girl quickly wrapped her left arm over her chest. "Wh-What do you mean by that? My name's Asami Lilith!"

The girl, Lilith, leapt off the water tank and landed in front of Arata and 'Hijiri'.

"What's with that amazingly sexy get-up?" Arata asked, trying to sound cool, but failing.

"Obviously, the battle suit for mages," Lilith replied.

"M-Mages?"

'Hijiri' giggled. "You should be getting a vague idea of what's happening, right?"

She brought her right foot forward and slowly drew a circle around her. From that arc, a ripple expanded through space itself. As the ripple passed, everything around Arata darkened and became ruins, as if left unused for years.

"What the-?" Arata gaped at the entire city, which had essentially become a ruined ghost town.

"This is the present state of your world, or at least, the world as you knew it," 'Hijiri' replied.

Lilith nodded. "Three days ago, a large-scale gravitation flux of unknown origin was detected in this area. We call this phenomenon the 'Sabbat'. This town was swallowed by the resulting explosion of space, and…"

Upon hearing her words, Arata felt his head hurt again, more intensely than before.

"Remember now?" 'Hijiri' asked.

That's right… Arata thought. I remember now.

Arata watched as the bright sun became engulfed in inky blackness. Immediately, people around him started screaming. A man near him doubled over, glowing purple cracks opening all over his body. The man's body exploded to release a bluish humanoid with a rocky body, short orange horns and orange cracks. The buildings standing all around them began quickly eroding and collapsing, as if they were aging on fast-forward.

All around Arata, people began exploding into clouds of purple dust, leaving similar humanoids or even other monsters in their place. As Arata stood, dumbfounded, he felt a warm hand grab his wrist and pull him away from the chaos.

"Hi-Hijiri?" Arata gaped at his cousin.

"We don't have time, just follow me!" Hijiri's voice was tense.

Hijiri dragged Arata into the shadow of a large piece of a collapsed building, pulling them both into a crouching position.

"Hijiri, you know what's going on, right? So tell me-Ah!" Arata was stopped mid-sentence by a sharp pain in his chest. He looked down and realized that a purple crack appeared on his clothes, as if his very being was breaking apart.

"This is bad…At this rate…" Hijiri mumbled. She dug in her pocket and pulled out something.

The item, on closer inspection, was a small book. The book was a small grey volume, about the size of Arata's palm. The book was bound with dark grey chains, locked with an intricate plus-shaped lock with a blue gem in the middle.

The book glowed in Arata's palm and the chains slid and wound around his arm. When the glow died, the book had vanished. In its place was a huge ring.

The portion where the gemstone was set was unnaturally large, with a huge clear crystal set into a silver bezel. Over the ring was a clear visor which had a trapezium on either side tapering towards the centre, forming bug eye shapes.

"Arata-san, take this," Hijiri quickly slipped the ring onto Arata's left hand, over his middle finger, which was also cracking apart.

"Hey, is this really the time for a proposal?"

"Please, save Arata-san. Grant his wish for him," Hijiri whispered to the ring.

"Who the heck are you talking to?" Arata demanded.

"Wake up on your own without me, alright?" Hijiri suddenly said.

"Huh?"

"Have three regular meals…remember to do the laundry every three days…and clean the apartment or it'll get…filthy…and…" Hijiri's voice started cracking badly. She leaned forward and pressed her lips to Arata's. Pulling away, she looked at him with tear-soaked eyes.

"Don't ever forget about me, alright?"

The moment those words exited Hijiri's mouth, her body began disintegrating into beads of bluish light.

"Wha-! Hijiri!" Arata reached out to grab his cousin's outstretched hand, but just as his fingertips were about to make contact with hers, her fingers disintegrated, along with the rest of her body. The last thing Arata saw of her was her teary, yet smiling, face.

Arata's hand closed around thin air, and he toppled over on his face.

"Hijiri…HIJIRI!" he screamed.

All too suddenly, his vision turned to black. All around him, a thick darkness that seemed to have a sticky texture engulfed him, though he still could see his body and hands clearly. They were still cracking apart into purple gaps.

"Stop fucking around! This is more than just a bad joke! Where is everyone?!"

He looked at the strange, heavy ring on his hand.

"Hey, whatever the hell you are, you can supposedly grant my wish, right?" he shouted at the ring.

"In that case, give me my normal everyday life back right now!"

As if responding to his yell, the clear gemstone unleashed a sudden, bright white glow that made Arata shut his eyes.

Arata let out a gasp. The headache that sent white-hot stings through his head finally cleared.

"I…made this…" he whispered.

"That's right," 'Hijiri' replied. "You wished for this, so I created this world just as you asked me to."

"I was surprised as well," Lilith added. "I was dispatched to this area to investigate the Sabbat that occurred here, but what I found was an intact town where there should be ruins."

'Hijiri' laughed. "It's as simple as a wave of a hand for the likes of me," she bragged.

"A dangerous grimoire…" Lilith cocked her rifle and expelled the shell.

"If you had failed, you would've increased the chances of Phantoms appearing instead of simply Ghouls. And creating another world on top of that…That's not something a normal grimoire can do!" she shouted at 'Hijiri'.

"That's exactly right," a male voice chimed in. The three turned to the door of the stairway, where a boy stood leaning against the doorframe.

"Arakawa?" Arata gaped. He quickly realized how bad the situation looked.

"Hold on, Arakawa, there's a reason for this-!"

"I know," Arakawa simply walked over casually. "You're a mage. And so is this girl here." He waved a hand to Lilith.

"No, that's not it!" Arata protested.

"More importantly, how does it feel?" Arakawa's eyes gained a predatory glint.

"Say what?"

"Your entire town, destroyed. Your cousin? Dead. You're simply clinging onto a shadow of her through that grimoire over there," Arakawa gestured to the blue-haired girl.

Lilith pointed her rifle at Arakawa. "Who are you?"

"Wait, it's my classmate, don't shoot h-" Arata began saying.

"No, no, Kasuga Arata. The human known as Arakawa Kouki is dead. He was sacrificed in the Sabbat and gave birth to a Phantom…me," 'Arakawa' gave a toothy smirk as blue, red and beige markings appeared over his face.

"Arakawa…" Arata felt his knees go weak.

With a roar, 'Arakawa' transformed. In place of the human, a humanoid bull stood. The humanoid was primarily blue, with beige armor covering his arms, legs and torso, as well as large shoulder pads. Grayish-white horns grew out of his head.

"Oh? A Phantom got pulled into the world?" the grimoire commented casually.

"Stay back!" Lilith shouted at the shaking Arata. "The situation got a whole lot more complicated."

Lilith's rifle glowed and disintegrated into beads of light, then she spread out her right hand in front of her. In a glow of red light, a pinkish-red book appeared before her.

Lilith murmured something under her breath, then light once again lit up the area. The red book now split into two bright red balls of light which each came to rest at the base of Lilith's middle fingers.

When the glow died, Lilith's fingers now bore two rings similar to the one from Arata's memory. On her left hand was the exact same ring Arata received from Hijiri, but with a ruby instead of clear crystal. On her right was a large round ring with a hand shape like the one on her belt buckle.

Lilith placed her right hand over her belt buckle, which responded with a red magic circle appearing over it.

=DRIVER ON, PLEASE=

The belt transformed into a silver one with a chunkier belt buckle. The hand shape was now set on a silver disc. The circle tapered to the belt in either side and each side also bore a squarish section, with the one on the right on top and the one on the left at the bottom.

Lilith now gripped the two sections and pushed them, switching their up and down positions. The hand shape was also shifted and now became the shape of a left hand pointing down and to the right.

The middle of the hand, where the base of the middle finger was, started pulsing with multi-colored light.

=SHABADOOBIE TOUCH HENSHIN, SHABADOOBIE TOUCH HENSHIN=

The belt suddenly chanted melodically, confusing Arata.

As the belt continued repeating its chant, Lilith flipped the visor on her left ring, which had been raised, down.

"Henshin!" she called and placed her left hand over her belt.

=FLAME, PLEASE~=

=HI, HI, HI, HI, HI~= (A/N: "Hi" (pronounced 'hee') here means flame in Japanese, more specifically the kanji '火'. I just used the original 'coz repeating 'Fire' sounded goofy…goofier, whatever.)

As the belt sang a new chant, Lilith stretched out her left hand to her side. A red magic circle wreathed in flames appeared where her hand was and slid to her right. As the magic circle passed over her body, flames formed new battle suit over her.

The new suit had a black bodysuit, with a black leather longcoat over the suit. The shoulders and collar of the longcoat were stiff and metallic, with round silver pads with carvings of a dragon in fetal position on each on the shoulder pads. The torso featured a red chestplate under the longcoat and the chest area of the longcoat had three huge rubies on each side, cut in quadrilaterals. Ruby red bands bound Lilith's wrists and ankles. Lilith's head was now encased in a black and silver helmet, with a mask that was a replica of her ring, down to the faceting on the red mask. On her left hip, a chain bearing several rings like the one on her right hand, but with orange gemstones, hung in a loop.

When the transformation ended, Lilith swung her hand down and the bottom of the longcoat fluttered up, revealing the red inside of the coat.

The Minotaurus reeled at the sight. "Y-You…You weren't just a mage? You're a Wizard, too?"

"That is right," Lilith replied. She removed the Driver On Ring from her right hand and plucked a new ring off the chain on her left hip. The ring featured a picture of a dragon emerging from a portal-like ring in silver, set on an orange gem. Lilith put the ring on and shifted the lever to switch the hand again.

=LUPACHI MAGIC, TOUCH GO. LUPACHI MAGIC, TOUCH GO.=

The buckle pulsed with light again, with the belt singing a new chant. Lilith scanned the new ring on her belt.

=CONNECT, PLEASE=

Lilith raised her hand to the side, where a magic circle appeared. She stuck her hand into it, disappearing into nothingness. Then, she pulled out a huge silver gun.

The gun's grip was nearly as long as the barrel, which was rather flat-looking. The top of the barrel had a folded section of what resembled a blade, curving in a convex manner. From the left of the gun, a large black left hand shape was set on the back of the barrel, where it connected to the grip. The left hand had its four fingers folded down, making the shape of a closed hand.

The Minotaurus, sensing danger, lowered his stance and charged at Lilith, who switched her ring again. This time, it featured a dragon holding an orange shield in front of it. Lilith shifted the lever back and forth once and activated the belt again. She swiped her hand over the buckle again.

=DEFEND, PLEASE=

Lilith held her right hand in front of her and a round disk of flames appeared, causing the monster to crash into it and be set on fire. The sheer heat of the shield melted the horns of the Minotaurus right off, leaving stumps growing from his head.

"Grr…" he grunted.

Lilith then replaced her ring yet again. This time, the ring featured the silver profile of a dragon's head, with three copies in cut into the gem itself. She activated and swiped her hand over the buckle for the sixth time.

=COPY, PLEASE=

A magic circle formed to Lilith's right, which quickly conjured a perfect copy of her in her battle suit. The copy and Lilith activated and scanned the rings again, creating a total of four Liliths. The four scanned again and formed a total of seven perfect copies of Lilith, with the real one among them.

The Liliths raised their guns and began firing at the bull humanoid, who tried to duck, but couldn't avoid the rain of bullets showering down on him.

Finally, Lilith stopped the shooting and her copies vanished, leaving only Lilith facing the monster. She now reached over to her gun and pulled the thumb of the left hand sideways, away from the palm. The fingers flipped open and the middle of the hand started glowing.

=COME ON A SHOOTING, SHAKE HANDS!=

The gun chanted in the same voice as the belt. Lilith placed her left hand over the one on the gun, looking like she really was shaking hands with it.

=FLAME, SHOOTING STRIKE: HI-HI-HI, HI-HI-HI=

As the gun chanted, a small magic circle expanded in front of the barrel. Lilith pointed the gun at the monster and fired rapidly. The gun blasted large fireballs at the bull, burning him up. When the firing stopped, the Phantom screamed and was burned to nothingness, leaving only a small flame on the ground.

Blowing out a sigh, Lilith transformed back, her battle suit disappearing into cascading gems of light.

"I'd better send a report to the Academy…" she muttered, bringing out yet another ring. This one was mainly silver, with the profile of a Garuda in ruby.

=GARUDA, PLEASE=

A rectangular model kit frame appeared in mid-air. The pieces immediately started detaching and assembling themselves, forming a small red model Garuda with silver detailing and a silver torso.

Lilith removed the Garuda Ring and attached it to a slot in Garuda's chest. The little familiar instantly sprang to life, flying circles around its mistress.

"I shall leave it to you, Garuda. Report back to the Headmaster," she instructed. The little PlaMonster let out an affirmative chirp and flew off into the distance.

"Now then…" she turned back to Arata and the grimoire.

Arata gaped at her.

"What the heck was that?" he shouted.

"Please refrain from yelling. That was a Phantom, a demon produced from humans affected by a Sabbat. And what I used was Wizard, a high-grade magic only top mages can use," Lilith explained calmly.

"Now that explanations are done," A cocking sound was heard and Lilith once again had her rifle in her hands, which she pointed between Arata's eyes.

"Choose, Kasuga Arata: One, have that grimoire dispel this fabricated world right now, and I can promise you'll live your days in peace. However, we will have to destroy that grimoire, and erase all your memories of Kasuga Hijiri and everything about this town."

"And the other option:" Lilith shifted her gun's aim. "I execute you right here as the individual responsible for the creation of this world."

Arata stared at the rifle in shock, then began laughing lowly.

"So if I want to live, I have to forget everything? Even Hijiri…"

Wait… A thought suddenly occurred to him.

"Wait, what happened to Hijiri? Is she still alive?" he asked the grimoire.

"She should be. This form of mine is but a shadow copy of her. It won't work if she was dead. She could be floating in a rift in time-space, lost somewhere in this world, or even in some other one, but she is undoubtedly alive," she replied.

"I see…" Arata muttered. "She's alive…"

He collapsed to his knees, but had only one thought running through his head.

She's alive…Hijiri's alive…I can find her…

After a few minutes, he spoke up again.

"I've decided. I'm not handing the grimoire over," Arata announced.

"Wha-?" Lilith gasped.

"But I have no intentions of being executed, either, though dying by the gun of a big-boobed beauty is tempting," he smirked at Lilith.

"I hate multiple-choice with only two options, so I'm making a third. One where I keep the grimoire, and stay alive, he cheekily stuck his tongue out.

"Selfish one, aren't you?" the grimoire casually commented.

"What are you on about?" Lilith demanded, her finger tightening over her trigger.

Arata looked up at the eerie black sun and reached out his hand, clenching it tightly as if trying to hold the sun.

"I'm gonna take option number three: I'll become a mage."
