Issei, Y/N, Koneko, and Gasper were now looking at Rias, who was being held by another Issei, but this one felt different.

Issei: You bastard! What are you trying to pull, looking like me!?

He runs forward, ignoring the pleas of his other comrades. Rias raises her hand up, producing a glyph, causing Issei to be launched back. Koneko jumps in and catches her. Y/N raises his hands up, preparing to fire a spell should he need to.

Issei: (disbelief) B-Buchou...?

Koneko: This ki...

Issei: Buchou! Get a hold of yourself! That isn't me!

She falters a little until she glances up at the fake Issei, who only grins and brings her closer.

Y/N had enough and knew that the fake Issei is using Rias's weakness of Issei's affection towards her.

Y/N: Cryo--

He was interrupted from casting his spell as Rias was quick on the uptake, raising her hand and quickly activating her magic and knocking Y/N back and hitting the wall.

The fake Issei caresses Rias's hair while the original Issei could only stare in shock. Y/N slowly gets up and mutters the spell he was trying to cast.

Y/N: (mutters) Cryogenic Element.

A small blue sprite leaves Y/N's finger tips and land at Rias's and the fake Issei's feet, freezing their legs. It was useless as the fake Issei raises his left hand, creating a bright red light that allowed all the other ORC members to see. Seeing that there could be trouble, they took off to see if they can assist in the situation.

Then in a split second, the roof of the Old School House building explodes. The light dies down and the whole roof of the Old School House building was scorched, missing the entire roof. There were still students around, wondering what was going on, unknown to them that a magical blast had occurred there. Soon, the Student Council caught wind of the situation and dispersed the innocent crowd.

Soon after, Issei is caring a wounded Y/N, who was suffering from the blast that he suffered from Rias. Later, Irina, Xenovia, and Kiba arrive on the scene. They spot Issei, Y/N, Asia, Koneko, and Gasper leaning up against the trees, with Y/N clutching his chest in pain. The others run on over and Irina puts Y/N's head on her lap, Kiba looking over his friend and Xenovia tending to the others.

Asia: Issei-san, what happened!?

Akeno: (walks up with Sona) We still don't know the details. Gasper-kun stopped time right before the explosion and pulled these three to safety.

Irina: Y/N...? Boo...? Come on, talk to me...please...

Y/N doesn't respond and was only letting out pained groans, still clutching his chest.

Irina: Come on Y/N, this isn't funny. Come on, wake up please...

He still doesn't answer and Irina starts to tear up, fearing the worst. Kiba puts a hand to Y/N's forehead and could feel him burning up.

Kiba: He's got a massive fever. How did this happen?

Sona: I can't believe something like this could happen on our school grounds. (eyes widen) Where's Rias?

Issei: (grits teeth) Dammit!

They hear footsteps walking towards them and they see Azazel and Rossweisse walking up to them.

Gasper: Sensei!

Azazel: Valhalla sent over an emergency message to Rossweisse. Loki did this.

Issei: What did you say!?

They all moved back to Issei's Residence. Irina had put Y/N in his room and they all reconvened in the living room.

Irina: An impostor Issei-kun?

Gasper: It's true. I saw him too.

Koneko: He practically had the same aura as Issei-senpai as well. Y/N-senpai recognized the danger and tried to stop him, but in turn, it's how he is now. 

Kiba: The same?

Koneko: If the real Issei-senpai weren't in front of me, I probably wouldn't have noticed the difference.

Akeno: Are you sure Loki is behind this?

Azazel: It seems the man himself said so. After he said what he needed to, he sealed himself away.

Xenovia: What a coward!

Kiba: This is a lot more effective than just defeating the enemy. Y/N and I suffered a long time ourselves.

Gasper: S-So what is Loki's real motive?

Azazel: The twilight of the gods--Ragnarok. He wants to destroy this world.

Asia: Um, where's Issei-san?

Azazel: Rossweisse is speaking with him.

With Issei and Rossweisse

Issei: A curse...?

Rossweisse: Yes. It seems he placed curses on you and Rias-san right before his capture. And it seems the curse that infected Rias-san somehow was able to make it to Y/N-san, who is currently in with a fever.

Issei: What do you mean?

Rossweisse: Curses attack and eat away at a person's heart. It exploits what's deep within your heart, perhaps something you don't even realize yourself. Loki used those feelings deep inside against you. Does anything come to mind?

Issei: I'm probably scared.

Rossweisse: You don't have to force yourself to speak about it.

Issei: I'm sorry.

Rossweisse: No, I apologize as well. I was ordered to confirm Loki's words.

Issei: Then you're saying that buchou has some doubt in her heart like me?

Rossweisse: You will have to ask her about that. Actually, it may be so deep within her that she doesn't even realize it herself.

Issei: (thoughts) With her crimson hair and dignified stature, how could there be something dark within the heart of the person I admire? Rias buchou...

In the Living Room

Issei and Rossweisse join everyone back in the living room. A projection of Ajuka and Sirzechs were shown to everyone, minus Y/N, who was resting in his room.

Azazel: Are you alright, Sirzechs?

Sirzechs: I am Satan Lucifer above all else. I will do what I must as a Satan.

Azazel: You're trying to hard.

Sirzechs: According to Asgard, it will take some time to break Loki's seal.

Azazel: If we could find out Rias's location from him at the very least...

Sirzechs: It seems she is in the Dimensional Gap.

Issei: Dimensional Gap?

Akeno: The place that Asia-chan was sent to?

Ajuka: I've searched using various methods, and it is the only possible location.

Xenovia: So we'll be able to save buchou if we go there?

Azazel: There is no systematic method of searching the Dimensional Gap. If Vali didn't happen to pass by at the right moment, we never would have found Asia either. In other words, entering the Dimensional Gap means death.

Akeno: Then how can those people enter it?

Azazel: The Khaos Brigade is a gathering of various factions. If Y/N was awake, we could know more about them as he has taken contracts from them before. But considering his situation, he won't be able to get any information any time soon. But we can conclude the Khaos Brigade is using a method that we aren't aware of.

Ajuka: This is a guess, but it's possible to lock the existence of this world and us it as a barrier.

Issei: Koneko-chan. I want to get in touch with your sister.

Koneko: With Kuroka-neesama?

Issei: (nods) ...I'll go see Vali.

Rossweisse: I understand the sentiment, but that's not possible.

Issei: Is it because he's part of the Khaos Brigade? I realize it's bad! But if there's no other option...

Sirzechs: The Underworld is being constantly attacked by the Khaos Brigade. They attacked again a few days ago. Many have fallen victim to their attacks. Their families, friends, and lovers are overwhelmed with grief. We can't associate ourselves with anyone from the Khaos Brigade just to save a Devil King's relative.

Ajuka: Even though Vali Lucifer is not part of the Old Satan Faction, one misstep and more malcontents like Shalba could spring up. This is something that affects the well-being of the entire Underworld.

Issei: (clenches fist) Rias buchou is important to me. I treasure her very, very much. That's why I have to go save her. That's all there is to it.

Sirzechs: Issei-kun...

Issei: I understand your position and the intricate politics involved. But for me, buchou...

Azazel: Then Issei...

Issei: Huh?

Azazel: Want to give up being a Devil?

With Y/N

Y/N was in his room, laying on his bed. Sweat was running down his face, neck, every where. In his mind, he was reliving his horrible memories in his past. His friends within the project telling him to run. Him seeing the people that lie dead before his blade. The ones he could have saved. They were telling him to join him in hell.

He screamed and when he awakened, he looked around to see that he was in Issei's manor. He felt his head laying on something soft. When turned over, it smelled nice and it was quite soft. Moving his hand up, he squished it. The thing squirmed and moved and he was still quite puzzled on who it was. He squeezed again and this time, a moan was heard. The voice was quite familiar to him. He lifted his head up slightly and saw chestnut hair. He moved up his head even more and his eyes were met with violet eyes.

When Irina's met with his, her eyes widened and she started to tear up. She immediately grabbed his head pushed it into her chest, hugging his head tightly. She began to let her tears out and she called his name.

Irina: I thought I lost you! I thought I lost you Y/N! I thought I lost you...I-I...I thought I lost you Y/N... 

He removes his head from Irina's chest and he kissed her, silencing her cries. He didn't want to worry her, but he always did.

Y/N: I'm sorry for worry you.

Irina: You better be, you big dummy.

She couldn't take it anymore. She wanted his touch, taste, everything. She brought his head up to her own and she smashed her lips onto his. She licked his lower lip and Y/N opened his mouth, allowing their tongues to fight for dominance. Eventually, she gave in and she let him explore his territory. He would later retract his and let her explore hers.

They separated and a string of saliva is what connected them. She intertwined his hands with hers and she squeezed it tightly. Y/N did the same as he didn't want to let her go. They laid in the bed, Irina patting Y/N's head as he rested his on her chest, not that she didn't mind.

Y/N: Where are the others?

Irina: They went to get Rias from the Dimensional Gap.

Y/N: Are they crazy!? She'd die!?

Irina: Don't even think about going!

Y/N: She'll die. If anything, Vali and his team are the only ones capable of travelling. I don't know how, but they are the only ones who can save her.

Irina: Don't go! Please...I don't want to lose you...

Y/N: ...I'm sorry.

Irina: What...are you...talking...zzz...

Y/N had promptly chopped the back of her neck, causing her to fall asleep. Y/N laid her on the bed and pulled the covers over her.

He made his way to the closet and pressed the false panel, which Zeoticus built in when he was remodeling Issei's home, and a secret door opened. He went in and grabbed his Blackwyrm coat and grabbed the Night Sky Sword and the Blue Rose Sword. He put on the coat, then equipped the sheathes on his back, putting the swords in their respective sheathes. He went down into a small compartment and took out a few health potions, which were made by Asuna.

He left the secret door and pressed the false panel, closing the door. He was about to leave, as he passed the bed, something grabbed his hand. She was still sleeping soundly and it pained him to leave her, but he had to save his friends. He gently loosened the grip of her hand and put on the pillow next to her. He leaned down and kissed her cheek, then the top of her head and leaned towards her ear.

Y/N: I'm sorry. I hope you forgive me. Wait for me. Please.

With one final kiss on her forehead, he gently opened the door and closed, traversing silently through the manor. He left through the front door and he looked at the manor one last time. A single tear went down his face as there was a chance that he wouldn't make it back. He pulled out his phone and looked for Vali's contact number. He hit the dial button and put it up to his head.

Vali: (picks up phone) Y/N, what a surprise. What't are you calling for?

Y/N: I need you to do me a favor.

Vali: ...What kind of favor?

Timeskip

Y/N had made a deal with Vali. The deal was that Y/N would not harm his team at all, thus allowing him to be taken to the Dimensional Gap.

Using the ability of Arthur Pendragon, he was taken into the same space as the other ORC members.

Kiba: Y/N!? What are you doing here!?

Y/N: Had to make a deal. Can't let the pervert die that easily.

Akeno: But what about your fever!? Shouldn't you be in bed still!?

Y/N: I'm fine. The fever died down. Anyway, where are they?

The others look down and point to where they are. Issei and Rias were fighting each other, both were in Red Dragon Emperor Balance Breaker armor.

Y/N: How did this happen?

Akeno: Rias is currently being controlled by Loki's curse. Right now, the only one who can stop her is Issei-kun, but perhaps you can stop her.

Y/N: ...I'll try the best I can.

Soon, the atmosphere of the Dimensional Gap changes, causing the ORC peerage members to be forced back to the human realm, leaving Y/N alone with two clashing anomalies.

Y/N stared at the two lovers and took a deep breath. He drew both his swords, and pointed the Blue Rose Sword in the direction of Rias. He closed his eyes for a moment, concentrating on his magical power. When he opened them, a golden yellow had surrounded him and his eyes were now a golden yellow.

Y/N: Release Recollection!

Blue ice-like tendrils spawn out of the Blue Rose Sword, tangling Rias, trapping her. Issei stopped and looked towards the direction of the attack.

Issei: Y/N!?

Y/N: Issei! Build up your power! I'll buy you some time!

As Rias struggled to get out of the icy vines, Y/N flew forward, putting the Night Sky Sword behind him and does Release Recollection, transforming the Night Sky Sword's blade to extend into a larger blade. He swung it down and Rias screams in pain, but quickly recovers. He flew high into the air.

Y/N: Generate all elements!

Multiple orbs of the different elements started to appear, circling Y/N. He flew forward and let them unleash. Y/N looks toward Issei.

Y/N: Issei! Now!

Issei flew forward at full speed and he deactivated his armor, extending his out towards Rias.

Issei: Rias!

His voice knocks Rias out of her crazed power state and her armor shatters. Realizing what she was doing, she flew to Issei and embraced him, thanking him.

While Y/N smiled, he sensed another presence appear. It was the fake Issei.

Y/N: Rias! Issei! I will buy you some time once more! Build up your power!

Before they could protest, Y/N flew forward to attack the fake Issei. The fake Issei activated Juggernaut Drive and the two went toe to toe. Y/N dodged the energy beam attacks and charged up the Sword Skill {Starburst Stream}.

Y/N: Starburst...Stream!

His swords glowed blue and he unleashed his barrage of sixteen hits, damaging the fake Issei. On the last hit, the fake Issei shot a beam towards his stomach, damaging Y/N in the process. He raises his right hand.

Y/N: Burst Element!

Red sprites leave his hand and they make contact with Juggernaut, exploding and causing small damage. Y/N saw his opening and spun around, using the Sword Skill {Double Circular}. Using Skill Connect, he followed up with the skill {Vertical Square}, using his left sword. The fake Issei uses one of it's wings to strike Y/N, causing him to stagger back.

This didn't stop Y/N and he flew forward with the Sword Skill {Vorpal Strike}, his Night Sky Sword illuminating red. He then followed up with his most powerful skill.

Y/N: Eclipse!

Using twenty seven hits, he struck the fake Issei with all his power.

Now exhausted, he looked towards Issei and Rias and said one thing.

Y/N: I leave the rest to you...

And then the black haired boy blacked out. But before he did, he saw Great Red appear, giving Issei his energy to help him defeat the Juggernaut Drive. He then closed his eyes and fell into the abyss.

Timeskip

A ringing noise could be heard as he awakened back in his room of the Hyoudou residence. As soon as he got up, he was brought into an embrace by the girl he loved.

Irina: You left me here, you idiot!

He let the tears out and wrapped his arms around the violet eyed beauty.

Y/N: Sorry for making you worry...Irina.

Irina: You better be...dummy.

Just as they were about to lean in, the door busted open.

Serafall: Y/N! You promised you wouldn't get hurt again!

Y/N: (terrified) S-Sorry, kaa-san!

Serafall: Irina-chan, hold him down! This is divine punishment!

He saw the magic circle produce in his mother's hand and his eyes widen in fear. He was suddenly pinned to the bed as Irina had locked his arms in place, flipping him over on his chest. He looked up and say the look of joy on her face.

He heard the magic charge up behind him and...

Y/N: Yamate kudasai!

Scene Change, ORC Club Room

Y/N and the others were in the ORC's building and Rias was sitting on the couch with Rossweisse sitting on the opposite one.

Rias: And so, here are some of the benefits you'll receive if you come to the Underworld!

Rossweisse: No way! The insurance premium is so cheap! And this one isn't even term life insurance! These terms are so much better than Valhalla's!

Rias: You bet!

Issei: Buchou looks just like a skilled insurance saleswoman.

Kiba: (sweat drops) She's buying off a Valkyrie.

Y/N: (sweat drops) This kind of skill is both impressive and terrifying.

Xenovia: So this is what they call a Devil's temptation. I could learn a lot from her.

Rias: (takes out Rook) So why not become a part of my peerage and work for the Underworld?

Irina: You're going to make Rossweisse-san a Devil of your peerage?

Issei: Is that okay, Akeno-san?

Akeno: Ara ara. Right now, only buchou and I are magician-types who use demonic power.

Koneko: It would be reassuring to have her.

Issei: You too, Koneko-chan?

Rias: I believe your power will be useful as long-range attacks.

Rossweisse takes the Evil Piece and eyes it. She grins and absorbs it, sprouting her Devil wings. Rossweisse was now the newest Rook of Rias Gremory.

Azazel: So you finally have all your pieces.

Issei: Sensei!?

Y/N: (two finger salute) Yo.

Rias: You're sitting in my chair without asking again!

Azazel: So today marks the true beginning of the Gremory Household.

Rias: (smiles) Yes, that's right.

Azazel: Oh, right. Issei!

Issei: Huh?

Azazel: The date of your TV appearance in the Underworld has been decided.

Issei: TV? Now that you mention it...

Gasper: Issei-senpai, that's amazing!

Y/N: (shakes head) No. No, really. It's not amazing.

Issei: But what should I do?

Xenovia: Considering everything you've done, will it be a hero interview?

Issei: Hero!? Me!?

Y/N: That's too much of a long shot.

Issei: No way! What can I say?

Later on

Issei: (projection) Boob Dragon is starting!

Kids: (projection) Boobs!

Xenovia: What is this?

Kiba: The Boob Dragon Song.

Koneko: Lyrics by Azazel. Music by Sirzechs Lucifer.

Gasper: Choreography by Serafall Leviathan and her son, Y/N L/N.

Irina: I didn't know you could dance?

Y/N: Kill me now...

Rias: (sigh) I went there with him, but I felt so embarrassed and uncomfortable I couldn't tell any of you.

Y/N: ...Issei...

Issei: Yes?

Y/N: You have five seconds...

Issei: Five seconds...?

Kiba: Prepare to run.

Issei: Huh?

The perverted boy then felt a malicious and killing intent in the air. Everyone looked to see that Y/N was brandishing the Night Sky Sword, pointing it at Issei.

Y/N: Five seconds is up.

Issei: (terrified) H-Hey, Y-Y/N. W-We c-can talk about this, right?

Y/N: ...

Issei: Should I be running now?

Kiba: Yes. You should.

Y/N: GET OVER HERE!

Issei: Yameru!
