Ichiban Ushiro no Daimaou - Volume 8, Chapter 3 — The Secret of the Demon King

There is an ugly beast that violates women in prison.

A treacherous beast that is feared and called a “Butcher”.

That’s me.

I was once a human but now I can’t even remember my own name.

I can’t speak, and I don’t understand a word they say.

It is in this deep loneliness that I am pouring my essence into the women everyday.

I pour my burning rage into them.

Over and over again, until they conceive.

From morning till night. Until the women’s souls withered.

To show them that I’m an excellent stallion and an obedient domestic animal.

But my soul has not perished yet.

I will break free from this prison soon. And when I do, it will be your last.

Every human who betrayed me, every demon who altered me, I will trample down like an ant.

And it won’t stop until I’m satisfied.

The dawn of the beast is near.

(following the boat) When a person who can get random superpowers every day enters the world of pirates and joins the protagonist group, what will happen as a result?

Luffy: “Si Guoyi! Lin Bei, let’s jump from the sky again!” Kebi: “Please don’t!” Sauron: “Be sure to leave Lin Bei’s room at twelve o’clock every day!”

Nami: “This bastard, just let me…” Akainu Sakasaki: “Bastard Lin Bei, turn me back into a man!

The old lady used her ability to come to her aunt once! “Big” boys, come and meet your father! “Lin Bei:!!! This really doesn’t exist!!!
