Brother

Katrina and I walk up to the front door of a grand looking mansion that just screams, "Hey I'm the prince of the empire who escaped! Revolutionary army come kill me!" This is partly because there was a sign declaring the first prince lived here and any cultists brave enough could come get their asses kicked by him.

I slither out of her shirt for a second and ask her, "Are you sure you want to do this? I know he is your brother, but he looks pretty dumb." She frowns, looks back at the sign, and gives a sigh that she only makes when I tell her to clean the dishes after diner. She only makes that sigh when she really doesn't want to do it but knows that she must.

"He's my brother. I just want to see him again because I was so sad when he died. Even if he is more," she looks at the sign, "'confident' in his actions, I want to tell him I'm okay.", I can only huff when I hear this.

"Okay, but please know I'll be here for anything that happens.", I say into her ear and slither back into her dress. She goes to knock on the door and yelps from me pinching her butt with my tail.

She knocks and waits for a minute and we finally hear footsteps behind the door. I could sense him in his bedroom, which is all the way in the back of the house. He has great senses, but no common sense.

"Yes, who is it? I don't have…much…Sister?", his brain freezes. He stands there with his mouth agape like a fish out of water. Katrina waves her hand in front of his face and he seems to wake up. He pulls her into the mansion and guides her to a study room with a table in the center.

"I never thought I would see you again. They said your body disappeared after the fight and I didn't hear word from you. What brings you to my home? If you haven't noticed I'm quite busy dealing with the cult behind the revolutionary army.", he asks in a professional voice. Katrina is confused by this because he was always the one that doted on her the most. She can't help but feel he isn't her brother anymore.

"I only heard about you being here recently, but now I'm not so sure you are my brother. Who are you?", she asks. I could answer her but she wants to hear the answer from him.

"You're right. I'm not your brother. I died in my original world from betrayal. This second chance was because he died, so I have a job to repay your brother. The cult will pay, and I will listen to one of your requests, but after that, please don't come back here again.", another reincarnator. At least this one isn't trying to fuck a bunch of underage girls, but a revenge seeking reincarnator is almost as bad as a harem seeking reincarnator.

He just screams darkness and hatred, can't even get over his past and enjoy his second chance at life. The worst thing is that he got Katrina's hopes up for nothing. The only thing she wants is to be happy and hearing her brother's voice brought her a little hope of seeing him again. I don't even have an excuse to beat the shit out of him, but I'm going to do it because I want to.

I go to pop out and beat him into a goblin, but Katrina puts her hand over her heart, and my tail, and gets up. "Thank you for clarifying that. I really hoped I could see him again, but that was just wishful thinking. I won't need your help in anything, so just don't interfere when I reclaim the empire I once lost", she says with tears in her eyes and rushes out of the mansion. She runs through tear after tear, not knowing where she's going but not wanting to be near him.

When she's almost out of energy, she pulls me out of her shirt and I return to my normal size. She cries into my shoulder for hours and only stops at the end to tell me one thing. "I want to remake our deal.", she says.

"Tell me Katrina, you know I won't deny it, but if it's what I think it is, you will have to give me much more than just your eye.", I tell her while holding her head on my chest.

"Please, destroy the cultists, destroy revolutionary army, destroy the entity, and destroy the thing that took over my brother. I will give you my everything and become your slave forever, just please, make them all disappear.", she tells me, and I accept. I don't want to hear her tears anymore, so I put my fangs in her neck and push a powerful love potion into her veins. I can synthesize venom that have different properties with my devouring ability.

I keep pushing it into her until I just hear moans of wonder and happiness. She calls me her most beloved mistress and I push an extra bit more, before stopping.

"How do you feel Katrina my love?", I ask her while caressing her face and looking deep into her ruby red eyes.

She looks back at me with the most wonderful smile and says, "I feel happier than I ever have mistress. I don't even know why I felt so heartbroken before. Please forgive me for showing you such a thing."

I frown at this because I want her to tell me all about her feelings, even if she is filled to the brim with my venom. "I don't want you to tell me that. Your emotions are important to me so tell me whenever you want to share them.", I tell her.

"Yes mistress!", she tells me happily.

I stand up and spread out my haki to the entire planet. I don't want to move for such insignificant people, but I'm going to make them suffer. I write seals for eternal pain on their bodies with word magic and let them die of shock.

The only one that was problematic was the reincarnator. He had an instant mastery cheat that mastered pain resistance. I just overpowered it and he was screaming on the floor for twelve hours before he was dead. You can't master something, only get better at it. He thought he mastered pain and I showed him how far away he truly was.

Now the contract is completed, I can get Katrina a new body from mother so that she can be my new sister.
