A/N: Thank you all for your support and review in the last chapter. This is the second idea I have, a KR Kiva and High School DxD. And on another note, please forgive me if you noticed mistakes. English is not my primary language, but I do enjoy writing in English. Please enjoy this little idea.
Idea 2: High School Kiva DxD
Rias Gremory and her peerage arrived in the abandoned warehouse sector by the harbor. The heiress of Gremory Family has received order to hunt a Stray Devil that said to be lurking around the area. The peerage walked around the abandoned sector and their red haired King frowned when she was unable to detect the presence of the Stray Devil she supposed to hunt.
"It's odd…I can't detect where the Stray Devil is," commented Rias before she turned to Koneko. "Koneko, can you tell where the Stray is?"
The white haired first year concentrated her tracking sense, only for her to fail. "I'm sorry, Buchou."
"Ara, ara, such a troublesome devil, hiding himself like that," said Akeno as she too looked for the devil they hunted.
"But isn't it weird, Buchou? He wasn't supposed to be capable of hiding himself like this," commented Yuuto.
"Maybe he possessed an item that lets him hide his aura," replied Rias.
The group explored the area a bit longer and uneasiness started to creep on the red head. She started to feel like the order she received was a false alarm, but she doubted as the order came from her own brother. A weirdo at times he was, Sirzechs wasn't the kind of person who would prank his sister on whims.
Well, embarrassing her maybe, but definitely not pulling prank against her.
They walked some more until a voice called out to them.
"Oh, is it for real? This must be my lucky day! Tasty, delicious little devils! Ahahahahaha!"
"Who goes there? Show yourself!" ordered Rias as she and her peerage prepared themselves for fight.
From one of the warehouse, a figure walked out. It was an adult man, wearing gray jump suit. His hair and eyes were dark while the expression on his face was best described as manic and blood thirsty.
"Who are you? Are you the Stray Devil that has been terrorizing this place?" asked Rias while keeping her vigilance on this…creature. He looked human, but her sense was telling her that this creature in front of her was anything but a human and definitely not a devil.
"Oh? You mean that guy from before? Hehehe, he was quite tasty I must admit. I wonder if any of you also tasted as good as he was? Is every devil tasty?" the creature leered, the hunger and madness in his eyes was unmistakable.
Akeno's eyes widened in shock while Koneko looked alarmed. "You…ate him?"
"Of course! I'm hungry and always am," replied the creature as stained-glass markings appeared on his face. "You too will become my food…Bon appetite."
The man changed before their eyes. His head was now become horse-like with blue vaguely humanoid body. His arms and legs were more bulky than human's, bellying the strength they had. Stained glass markings also covered a portion of his face, chest, arms, shoulders, and legs.
Rias looked alarmed at his monstrous transformation. She had never seen anything like this before, not even a Stray Devil was capable of this. Yuuto drew out his sword while Koneko settled into fighting stance. Akeno's expression tightened as sparks danced in her palms and Rias flared out her Youki, her face was set into fierce frown.
"What kind of creature are you?" asked the Gremory heiress.
"Ha! I don't need to answer my morsels!" jeered the horse monster as he smashed his chest, letting glass shards fell. The shards then reformed into a sword at his foot before he kicked it up and caught it with his hand. "But if you decide to fight…then don't make it boring! Best foods are always the ones who struggle the most!"
The monster charged at the group, his intent was clear to them. Just when the Gremory Peerage's frontline fighter intended to intercept him, a small white and black blur blindsided the monster and attacked it rapidly. The blur then attacked the creature one last time and staggered him.
"Argh! Who dares interrupting my dinner!?" he demanded angrily.
"My, my, such a rude fellow. And very greedy too, no wonder you were ordered to be eliminated," said the blur as it floated lazily in the air. The blur was a cartoonish looking mechanical bat with black and white trimmed, roundish body and a face with big red eyes and small green triangular gem on the forehead that fused into its body. It had a pair of triangular ears on the top of its head and black wings on each side, with the same color of its body. Its small leg was located under its mouth which has four pointy fangs. It was Kivat-bat V.
"YOU!" bellowed the creature with a mixture of anger, surprise, and a hint of fear.
The sounds of approaching footsteps caught everyone attention as a person walked from the darkened alley between two warehouses. That person's clothing was consisted of a brown jacket with red shirt underneath, blue jeans with a black leather belt, and white-on-red sneakers. As the figure stepped out of shadow, the Gremory peerage couldn't hide their surprise as they realized who it was.
"Kurenai-kun?" whispered Akeno in surprise.
"Takeru-senpai?" said Koneko, also shocked seeing him here.
"Takeru Kurenai? What is he doing here?" muttered Rias.
"Perhaps, he has something to do with that monster, Buchou," asked Yuuto unsurely.
Takeru didn't make any gesture to acknowledge the Gremory peerage as his sole attention was focused on the horse monster.
"Galloping Glutton of Shining Plains Realm," he called out, his voice was firm and steady with authority, not showing any kind of shyness he usually displayed on the school. "You have been endangering the safety of the Fangire race as whole by feeding on humans and devils. How do you plea?"
"Endangering!? All I've done is getting my meal! The ones who endangered the race are the Checkmate Four!" snarled the Horse Fangire as the image of his human persona appeared on his chest. "They supposed to protect the whole Race, but all they do are endangering us by starving us! Especially King! He, his father, and grandfather are the one at fault! Those human loving fools!"
"The law made it clear you cannot drain the life energy from human, except from few exceptions. And now you have stepped into the boundary of devils' territory. You have been endangering the Fangire race as a whole for the possibility involving them in a war with devils by feeding on them," replied the brunette.
"Because I am hungry! I want to eat and that's final!"
Takeru closed his eyes and sighed. "So you choose to follow your greed than the safety of your race. You really lived up to your name, you hypocrite." He opened his eyes and glared at the Horse Fangire as he called, "Kivat!"
"Understood! Shall we begin, aibou?" replied the bat as he fluttered around Takeru.
The brunette caught Kivat in his left hand and pressed the top of its head with his finger while bringing his right hand to Kivat's mouth.
"GABU!"
Kivat bit into Takeru's hand, causing stained-glass markings to appear on his face as hypnotic sonar noise resounded. Ghostly chains wrapped themselves around his waist, before they shattered and revealed a red belt with a roost in the place of buckle and three slots for various colored whistles called fuestle on each side. Takeru pushed the hand that was holding Kivat forward as he uttered a phrase.
"Henshin."
He then let Kivat hung upside down on the roost buckle as quicksilver formed around him before shattering and revealing his new form. His body was covered in black body suit while his head was covered by black helmet with big yellow lenses that shaped like bat wings and small circular gem on his forehead and silver mouth plate with black fangs while the jaw guard was also silver. His armor was silver with high collars and red breast plate that mimicked human's torso muscle. His shoulders were covered by armors that looked like folded bat wings restrained by silver chains while his arms were bare with silver bracelet and red armored gloves. His left leg was also bare save for silver knee guard, anklet, and shoes, but his right leg was covered by silver boots with chains tightly wrapped around it, as if it was holding back something.
The Gremory Peerage looked surprised at Takeru's transformation while Rias watched his armored figure with undisguised interest.
"Kiva…you bastard!"
Takeru, now Kiva, calmly settled into a fighting stance as the Horse Fangire charged at him, roaring. He ducked and dodged the sword slashes from his adversary and he kicked him on the chest. Kiva disarmed Horse Fangire with another kick and punched his chest rapidly before he sent him flying with a solid uppercut to his chin. As the monster stumbled away, Kiva decided to press his advantage by charging forward. The Fangire, however, smashed his chest once more and this time the glass shards hovered in the air before emitting bright flash.
"Gah! That crafty little—!" cursed Kivat from his perch as Kiva covered his eyes from the blinding light.
Horse Fangire quickly recovered his sword and struck at the still recovering Kiva. He slashed his chest twice before bringing his sword for an overhead slash.
"DIE, KIVA!" roared Horse Fangire as he brought his sword down, only for Kiva to caught his sword with his palms. "What!?"
Kiva grunted as he pushed the sword away and shoved the Fangire away with a kick, once more disarming him. The vampiric warrior unleashed double roundhouse kick that made Horse Fangire reeling before a brutal haymaker knocked the kaijin down. Horse Fangire tried to recover, only for a snap kick launched him to the air and a straight kick from Kiva sent him crashing toward stacks of barrel.
"Time to pull the curtain down, Takeru!" ordered Kivat.
Kiva nodded and took one of the fuestles on the right slots, one with transparent body and red part on the top that depicted bat wings, and slipped it into Kivat's lip.
"WAKE UP!"
As the mysterious tune played, Kiva brought his hands to the side with his knee bended before slowly crossing them in front of his face as he put one of his legs behind the other. The atmosphere suddenly changed, catching the Gremory peerage by surprise when the moon became larger and glowing with eerie pale yellow light while also becoming a full moon which quickly shifted into crescent moon. Kiva suddenly kicked his right leg up as Kivat flew from his perch, circling around his armored boot as a peculiar four tones played and the chains shattered, revealing the bat wings with red inside and three green gems hidden. His left foot tensed before he jumped by impressive height despite only with one leg. In the apex of his jump, Kiva back flipped and coming down with his winged right leg pointed downward and left leg tucked.
"Darkness Moon Break!"
He hit Horse Fangire with massive force and bat wing-shaped crater was formed on the impact zone. The body of Horse Fangire seemed to crystallize before shattered and freeing the light ball inside it. The chains reformed on his right leg, sealing it close once again.
Kiva looked at the fleeing light ball and took another fuestle, also transparent with red shades that depicted a dragon head on a castle, from the slots on his right side and put it into Kivat who blew it.
"CASTLE DORAN!"
Several seconds later, giant wing beats and a draconic roar was heard. Rias and peerage turned around and they found something they would never believe if they didn't saw it. Flying in the sky was some sort of dragon/castle hybrid. Its main body was the gray colored castle with the main entrance where the dragon's neck came out with purple scales on the top while its lower jaw and neck's scale was white and a pair of gray horns on its head. There were two watch towers on each corner in the front while its stocky legs came out from the bottom, bound by golden manacles and chains. Its short yet powerful wings came out from each side of the outer walls and its tail was ended with another watch tower. On the top of the castle was a small clock tower and a door that lead into castle interior far in the back.
"Is that a dragon? Or a castle?" asked a puzzled Rias.
"I think it's both, Buchou," answered Akeno.
They watched as the dragon/castle hybrid chased the light orb before swallowed it with an audible gulp. Doran then landed with booming noise and belched loudly.
"Hey, hey, that's not a polite thing to do, you know?" commented Kivat from his perch on Kiva's buckle as the magical phenomenon receeded.
Kiva turned to the Gremory Peerage who was approaching him curiously and warily, as if he was turning against them in a notice.
"On the behalf of my Peerage, I thank you for your assist tonight, Kurenai-kun," said Rias as a smile graced her beautiful face.
Kivat flew from his perch, floating next to Takeru as he cancelled his transformation. "It was nothing, Gremory-Senpai. I was also hunting that Rogue Fangire for a while, so…like I said it was nothing." Here the shyness of Takeru Kurenai has returned, he was becoming more like the person Akeno and Koneko had known.
There was that word again. Fangire. It seemed they were some kind of monster race she never heard before. Still with a smile on her face, Rias continued, hoping to learn something from her kouhai.
"Then, you don't mind to share information with me, right?"
"I'd love to senpai, but can it wait for tomorrow? I promise I will answer the question you asked as best as I can," requested Takeru.
The red head seemed to ponder about before Akeno tapped her shoulder and nodded, signaling to accept his request.
"Very well. I'll save my question for tomorrow," answered Rias with a reluctant sigh.
Takeru smiled and bowed to her, "Thank you very much for your understanding, Gremory-senpai." He stood up and addressed the peerage again. "It's been an eventful night and I think I'm going to get some rest. Good night everyone."
They watched as the dragon spat an orange energy orb that encased Takeru and Kivat which floated and got swallowed again by the dragon before it took flight and disappeared into night sky.
"So, do you know anything about his little secret?" asked Rias to Akeno and Koneko.
"I don't know, Buchou," answered Koneko.
"Neither do I," said Akeno as her eyes gained a strange gleam and she shivered. "But you do feel it, don't you Buchou? The power Kurenai-kun wields…It was so intense and intoxicating."
"Was that a Sacred Gear?" asked Yuuto.
"I don't know, but the horse monster called his armor 'Kiva'," replied Rias as she looked at the direction where Castle Doran was last seen. "I'm looking forward to learn more about you, Takeru Kurenai."
A/N: So...how was it? Please tell me what you're thinking about this one. The OC here, Takeru Kurenai, is the grandson of Wataru. And I have some dilemma here. Should I let Issei join the peerage or let Takeru have the Boosted Gear, leaving Issei as an extra character for comical relief? The only thing I have against Issei that he is a pervert and the majority of his power up is based from his own perverseness. And that's...kinda turned me down. That is all for now.
