In an interrogation room, Y/N was seen being tied up to a chair as he remained motionless and his head was hanging down.

Agent Two: Gotta say, we're disappointed in you, Y/N. We could've handled the situation like civilized humans, but you had to throw yourself away at the hands of the hellhound.

Y/N: ...

Agent One: What do you have to say for yourself, traitor?

Y/N: ...

Agent One: Nothing, huh? Not even for your last words?

Y/N: There's nothing for me to say... to you bastards...

Agent Two: Mourning for your parents, huh? Well, save your tears. They're wasted on a bunch of backstabbing traitors.

Y/N: Traitors... Is that all you see in us...? Just because you saw how we were associating with her? You don't know a fucking thing about what's happening between us.

Agent One: *shakes head* WAKE THE FUCK UP, Y/N!!! That fucking dog has manipulated you into joining her group of mindless and heartless demons hellbent on conquering our world! And unless you want to end up like your fucking associates, you will understand what's going on, right now.

Y/N: That "fucking dog" is the reason why I'm happy. Sure, we didn't know each other for very long, but I knew her well enough to understand her pain... while you fucking dumbasses assume that she's done nothing but spout a bunch of meaningless lies in order for me to join her. My parents and my unborn sister died to some blind justice? Give me a fucking break...!

Agent Two: It's just a fucking dog! Why do you care so much about that stupid mutt?! It's nothing but a mindless monster.

Y/N: *eyes widen* ... How dare you...?

Agent One: Hm?

Y/N: *clenches fists angrily* How fucking dare you call Loona a MINDLESS MONSTER?! If anything, YOU'RE THE MONSTERS, HERE! You killed my parents because you think you know the demons, yet you don't know a fucking thing about them! And that... That is what made my family perish... Where is she...? WHERE IS LOONA?!

Agent One: Wouldn't you like to know. Don't worry. If you want to die alongside that demon, you'll see her, again, in Hell. Where you belong.

Y/N: Wrong. You all deserve to be in Hell. For murdering my parents in cold blood! And for ruthlessly killing my sister who was yet to be born in a few months!

Agent Two: If there's anyone to blame, blame that demon! Better yet, blame yourself for choosing to side with the hellhound.

Y/N: THAT DEMON'S NAME IS LOONA! You don't know one fucking thing about her and now, I swear to fucking God on my parents' grave, I'll make sure you all suffer for what you took from me. What you stole from me! WHAT YOU KILLED FROM ME!!! You always called me a traitor to humanity because of my newfound love for Loona, so you wanna now what? I'll happily accept the fact that I'm a traitor to humanity, knowing that if this is what it means to be human, THEN I'D RATHER FUCKING DIE THAN EVER BECOME THE LIKES OF YOU BASTARDS!!! So you can either give me back BF/N and Loona and let us go OR YOU CAN DIE SCREAMING ALONGSIDE YOUR WORTHLESS AND PATHETIC AGENT BUDDIES SO THAT YOU WILL FINALLY UNDERSTAND WHAT IT TRULY MEANS TO BE A DEMON!!!

He panted heavily as Y/N was now full of anger. Not a single ounce of who he was before could be seen behind his eyes. He was now a vengeful spirit hellbent on revenge against the people that took F/N, M/N, and his baby sister from him.

Agent One: ... You're too far gone, now. You don't deserve to be a part of this world, anymore. But, we'll get to you in a moment. Right now, we have to deal with that hellhound. In the meantime, our buddies here can soften you up before your death.

Y/N: ...

Soon, more agents came in with weapons.

Agent One: Humanity will finally be free from your plague of traitorous deeds and then, demon kind will never set foot in our world, again. See you soon.

They left the room and the other agents chuckled.

Agent #5: No one's coming to save you, now, traitor. You're all alone.

Y/N panted heavily as he kept replaying to his parents' deaths and how his baby sister would never get a chance to live her life, feeling the sadness and rage he felt. One of the agents walked up to him, but suddenly, Y/N kicked the agent's leg, causing him to fall to the ground on his knee. Y/N then kicked his face, but this time, the impact he left behind was more violent and hateful to the point, he left behind a broken nose. Y/N then shockingly got up on his feet, despite being tied up to the chair. The agents were surprised to see this, but they charged at him. Y/N swung the chair that was behind him and used it as a weapon to inflict pain on the agents. One of them tried to swing his axe at Y/N, but Y/N used the chair to halt his strength and swung the chair at his face. After kicking him down, he noticed another charging at him, but Y/N tripped the agent using the chair leg and the agent fell to the ground. Y/N then jumped from the agent's back and flipped in the air to his back, causing him to the other agent to break the chair. The agent screamed in pain, but Y/N was able to free himself. Upon doing so, he turned to the other agents.

Y/N: So... Who's first?

The agents could feel the tense air in the room as they looked at Y/N. However, they charged at Y/N.

The axe was implanted against the agent followed by many others that were decapitated, mangled, chopped up, disarmed, and lost body parts. The time had fast forwarded to when Y/N was able to kill all of the agents, leaving behind a room full of dead bodies and blood splattered all over the wall.

Y/N: *wipes blood off face* ...

Unable to say anything, Y/N used an axe to break open a window to the other room and jumped through it. He then walked out the door and left the room. However, more agents took notice of him and charged at him, but Y/N clenched his fists angrily. Meanwhile, BF/N was seen in another interrogation room as he tried to escape, but to no avail.

BF/N: *bangs door* Damnit!

He walks away as he thought back.

BF/N: ... *sighs* Is this how we're really going to die? At the hands of these... bastards? It's just not right! We were just living a good life. How could it spiral out of control like this? ... I can't believe this is actually happening... Y/N, Loona... *clenches fists* Fuck!

Suddenly, he heard screaming outside the door and turned to it.

BF/N: Huh? *approaches door*

Y/N: *muffled* Where is he?! Where's BF/N?

Agent #6: Fuck you!

BF/N: Y/N? ... Y/N, I'm in here!

He continuously banged on the door and tried to get his attention. Outside, Y/N heard the banging and went to the door.

Y/N: BF/N, you okay?

BF/N: Am I okay? What about you?

Y/N: I'm fine. Just... hang on. I'll get you out.

BF/N: No! Y/N, listen to me. They're planning to do something to Loona. I-I don't know what it is, but it's not good. Listen, I'll be fine, but you need to find Loona first.

Y/N: What? What about you?

BF/N: Don't worry about me, right now! You know where I am, so once you get Loona, come and find me. Then we'll get out of here.

Y/N: ...

BF/N: Y/N... I'm sorry for what happened to your parents and your sister. And I can tell that you wanna make these assholes pay, but right now, we need an escape plan to get out of here. Go and get Loona. Find her!

Y/N: ... O-Okay. Just stay put. I'll be right back. *runs away*

BF/N: Stay put... Heh. Not like I'm gonna go anywhere.
