After Loona backed away from the fight, Y/N got in position to fight Louis.

Louis: Heh. Looks like you haven't been slacking off. Has your time away from your parents make you intensify your training?

Y/N: Shut up! Don't bring them into this!

Louis: Ooh. Struck a nerve, kid?

Y/N: ...

Louis: Hmph. Well, it matters not. I have made a huge profit after I sold your home. I'm not saying I'm responsible for your family's death, but damn. Selling off the house like that has given me a fucking fortune! F/N was a great partner, but he was too judgy over everything. Always so cautious. And then, when you were brought into this world, F/N has become a different person. I should've killed you when I had the chance, but now? I have no personal remorse against you, kid, but your existence is bad for business. You and your friends over there. Hehehehehe. Don't worry. Once I kill you and the others, I'll take good care of your girlfriend. Spoiler alert? She'll make a nice sex slave for the company.

Y/N's pupils dilated and turned demonic when he thought about Louis abusing Loona. He growled angrily and ran to Louis. Louis grabbed a grenade from his jacket, but before he could pull the pin, Y/N used his magic to knock it out of his hand and over to Blitzø.

Louis: What the...?

He was then punched in the face by Y/N and then was elbowed into the stomach. He exclaimed in pain and as he tried to recover, Y/N kicked him in the face and knocked him to the ground, breaking his nose and causing it to bleed. He screamed in pain.

Louis: Ah! My fucking nose! Argh!

Y/N: Hmph. Can't tell you how good that felt. And by the way, that was for all of the people that you robbed from their homes.

Louis stood back up and recovered from the hits he took.

Louis: You goddamn brat!

Y/N got on one knee and placed his hand on the ground. With enough pressure and strength, he launched himself at Louis and kicked him in the face.

Blitzø: Whoa. Seems like Y/N's gotten aggressive.

Moxxie: Probably has something to do with how he threatened Loona.

Blitzø: Guess that goes to show how much he loves you. Right, Loonie?

Loona: *blushes* Hehehe. Yeah. I'm glad I have someone like him as my boyfriend.

As she blushed, her tail wasn't visible, but it was wagging happily as she watched Y/N beat up Louis. After performing some acrobatic kicks, Louis was losing balance and Y/N grabbed his shirt.

Y/N: You're not laying a finger on my Loona!

Louis tried to headbutt Y/N, but he groaned in pain and realized that Y/N didn't even flinch.

Y/N: Hate to break it to you, but...

He then grabbed Louis' arm and snapped it in half and he screamed in pain.

Y/N: That kind of body is useless against me. If anything, you haven't had any form of practice done to your body. Maybe if you took the time to practice, you'd have a chance. But, you've been a lazy ass coward and for that, you don't have a chance.

Louis: Don't get cocky!

He grabbed another grenade, but Y/N grabbed his hand, causing him to drop the grenade.

Y/N: You're full of surprises, aren't you? You know, despite the fact that you have all of the weapons tucked away in your suit, you lack skill and precision.

He then broke his hand and threw him to the ground.

Y/N: Someone as heartless and selfish as you deserves to rot in Hell. Loona? Care to finish the bastard off?

Loona: ... Sure. Why not?

Y/N: Blitzø?

Blitzø nodded and handed Loona his gun. She walked to him while Y/N pressed his foot against his back to prevent him from making any movement.

Louis: Please... Have... mercy...

Loona: Sorry, but I don't know anything about mercy against bastards like you.

She then pulled the trigger and shot Louis in the forehead, killing him in the process.

Loona: ...

Y/N: You did the right thing, Loona. Don't let him get into your head.

Loona: It's not that. He begged for mercy, N/N. And I didn't give it to him. Are you sure you want someone like me to be your girlfriend?

Y/N: *smiles* Of course I do. I mean, despite the fact that Millie has a crazy personality, Moxxie still fell for her, right?

Loona: ... Yeah. I guess you're right.

Y/N: Hey. Remember what I said at the office. You're everything I wanted to be. Don't let anyone tell you different. Okay?

Loona: Okay. Thanks, N/N.

Y/N nodded and they both kissed.

Blitzø: ... I can't take it! It's just so much!

They then let go of each other.

Loona: Come on. Let's head home.

Y/N: Sure thing. But, let me do one more thing. I'll be right back. I promise.

Moxxie: Don't take too long, N/N.

Y/N: *laughs* Moxxie, when have I done otherwise?

He then opened his wings and flew away. Everyone watched as he did.

Moxxie: You know, for being the last hybrid alive, he has such a positive attitude towards everyone.

Loona: Yeah. But, that's why I love him. I'm glad that someone like him exists.

Blitzø: If M/N and F/N were here right now, they should be proud of how they raised him.

Loona: I'm sure they are.

After a while, Loona felt her phone vibrate and looked at it as she got a text message from Y/N.

Y/N (Text): Check the news.

Loona got confused and looked at the news with the headlines saying "Young Man Sells Ten Trillion Dollars To Orphanage". Everyone went outside and looked to see Y/N leaving the crowd.

Loona: How'd you do that?

Y/N: Turns out Louis had a lot of cash left over. And now, the kids can continue to do what they want while they wait to get adopted.

Blitzø: N/N, you sly son of a bitch...

Y/N: *chuckles* I have my ways. Now, we can go home.

He then turned around and rolled up his sleeves. He then summoned some magic and opened a portal back to I.M.P. and everyone returned home.
