Kuoh Academy was a lively place where students had fun and excitement but now it is a land of fear. This is where Issei, Ravel, Siris, Ni and Li found themselves. The others are either training or don't want to go to school. They are wearing the school uniform and the twins are wearing illusions to hide their Neko features while Issei has bandages on his left arm and contacts to hide his Kure eyes.

Issei's knight looks and many of them are afraid of something. "Something is wrong. They are looking as if they saw a nightmare."

"You're right Siris. We should find out what is wrong." He looks around and sees his two old friends. "Perhaps they can answer. Matsuda! Motohama!"

The two of the Perverted Trio look at their friend and look happy to see him. "Issei! Thank god you are alive!"

The Devils shiver from the name of god but Issei is confused by what he said. "Alive? What do you mean?"

"You haven't heard? It's Aika, she-"

*DING DONG*

The school bell stops Matsuda from explaining and quickly goes to class but not before warning him. "They'll properly tell it at homeroom but please Issei, don't go after dark."

Ravel turns to Issei as they walk together. "Do you know a Aika?"

"Aika Kiryuu is a friend in the academy but what happened to Glasses Girl?" Issei enters the classroom and sits down while the others stand at the front. He sees Koneko sitting and notices him but she just scoffs and ignores him which makes Issei roll his eyes. The teacher enters with a grave look. "Hello students, as you may know, Aika Kiryuu was murdered last night. There is an investigation and we can only pray that the killer is found and brought to justice. Please welcome four new students."

They give their fake names and sit next to Issei, who is shocked by Aika Kiryuu's fate. Ravel pats him on the side. "Issei…"

"We were friends and someone killed her. We are going to find the killer ourselves." He declares with his eyes showing resolve and no hesitation. After class, they walk outside and are about to leave but Koneko stops them. "Guys, head to the murder scene. I'll deal with her."

They leave and the Neko girl and Kure boy are behind. "What do you want Neko?"

"Buchou demands your presence Perv." Koneko's dry voice annoys Issei and just scoffs. "I don't think so. Tell her that if she wants to talk, she can come herself and we can talk."

He turns away and as his back is turned, he ducks a kick and Koneko glares at him. "Shut it, you're coming or I'll wreck you."

"Let's take this outside." They go outside and head into the forest. He takes off his shirt and throws it to the ground. Koneko notices he takes off his bandages on his left arm to show his Boosted Gear. "Ready when you are Kitty cat."

"Sure lizard boy." The Rook prepares as does Issei, though he can hear Ddraig.

"Are you sure you can fight her? You wanted her in your hypothetical harem."

'She is an enemy and I'm not merciful to people that want to harm my peerage.' They clench their fists and punch eachother, creating a shockwave.

Ravel, Siris, Ni and Li find themselves in the crime scene where cops and detectives are surrounding the area. Siris looks at Ravel. "Any ideas ma'am?"

"Hmm... " The Phenex heiress looks around at the crime scene and notices blood spots heading into a back alley. She motions her friends to look at the alley and they go into it. They follow the blood trail until they hear yelling. They run to the other side of the alley and find Irina and Xenovia unconscious. Siris runs to check on them and notices something missing on both of them. She sniffs the air and takes out her Zweihander and blocks an attack from a figure.

"Piss and hypocrisy. A stray exorcist if I ever smelled one." She jokes and the figures snarl. "Keep talking bitch and your corpse will be more cut up!"

"Siris be careful! That's Freed Sellzen, a psychopath exorcist!" Ravel summons flames but it is destroyed by another figure. A tall man in a black overcoat comes out holding machetes in each hand. "Well, well… Come on Freed, is this all you can do?" The man said in an American southern accent.

"Fuck off Red Sun!" Freed insults his companion and he slashes at Siris but she jumps back as Ni and Li palm strike the disgraced exorcist together, making him spit out drool and blood. He gets more piss off and his blade glows.

"I'll kill you all! Excalibur Nightmare!" Freed creates illusions of himself and surrounds the knight and twin pawns. The Devil trio stand together and charge against the despicable exorcist.

Ravel flies as Red Sun follows her and jumps next to her. Her eyes widen as she creates a flame barrier but the man breaks with just the force of his weapons and she falls but is able to land on her feet. "I understand now, you are Red Sun. The bloodthirsty mercenary known for slaughtering entire groups of supernatural beings."

"Aw shucks little lady. You'll make me have red all over my face." Red Sun jokes then begins to be sadistic. "Course, that's going to be your blood when I'm done with you."

Ravel creates an explosion which hits the mercenary but he laughs as it only seems to tickle. He raises his machetes and swings down yet she dives under the man and creates fire which hits his face. He however keeps smiling as his face burns. "Don't you know missy? I had an operation that disable my nerve receptors. In other words-"

"You can't feel pain." Ravel finishes the explanation as she ducks another attack but instead hits a pillar. She touches another pillar and overheats it which weakens the foundation of the building. He tackles her to the ground and prepares to finish her off but then the building breaks off and begins to fall.

Ravel kicks him and runs as the building falls on top of him. She checks on Irina and Xenovia to heal them.

Siris blocks the strike from an illusion as she and the twins try to find the real one. "Ni! Li! Take him out."

"Working on it!" The twins exclaim together and hit the illusions. They nod to eachother and breathe in as their Neko features become more prominent. Life energy enters their bodies and launches themselves at the illusions. They punch the figures with a mere punch and they disappear. Freed tries to kill the Neko twins and raise his sword in the air but Siris appears behind him and cuts his arm off. He shouts in pain and curses at the women as his hand holding the sword falls.

"Fucking bitches!" He yells as he is teleported away. Siris picks up the sword and notices it appears to be multiple swords fused together and walks to Ravel, who touches it but feels a sudden burn.

"A holy sword. You must be able to touch it because you were once human. Take it, you probably know how to use it better than anyone."

"Thanks ma'am." Siris said as she sheathed the blade. They turn to check on Ni and Li but the twins are gone, as if they teleported. Laughter stops them from looking for the twins and see Red Sun impaled on rebar. He smiles at the Devils and warns them of an event coming.

"You clearly have no idea what you have walked into. You're entering a war you cannot imagine."

"We will stop your masters and avenge Aika Kiryuu." Ravel said but Red Sun is confused by the name and dies with a question he whispers.

"Who?"

Koneko flips above Issei and lands on his back and puts him in a headlock. She uses all her Rook strength to choke him out. He runs into a wall and slams his back on it and the Neko holds on. Issei gets on his knees, about to black out but he grabs her by the hair and judo flips her to the ground. He moves his fist at her but she rolls out the way and creates a crater.

He runs at her and kicks her but she ducks and grabs his leg and side sweeps him to fall. He grabs her face and lifts her while he is still on the ground. He gets up while still holding her and throws her on a tree.

BOOST

"Come on!" Issei shouts and punches Koneko in the jaw, crashing through the tree. "Fight for real Shirone! Pull out your ears right now or I'm putting you in a coma!"

"Why? So you can oogle your kink?" Koneko jokes as she gets up and jumps to kick him in the head. He crashes and bounces twice on the ground. He quickly gets up.

"No… I want you to accept your past. I hate people that don't accept their past, who just want to forget who they are. You are a Neko, accept it!"

They are about to clash and punch each other but stop once they hear footsteps. They both turn to see Ni and Li walking towards them. "Guys, what are you doing here?"

"Are they… No, they have succumbed to Senjutsu madness!" Koneko warns Issei as the Neko twins roar and run at them with insanity in their eyes.
