I'm an oni!

"Oni"?

Yeah! An unyielding wicked god!

And so are you!

Truth be told, I was gonna rob you blind and eat cha...

But since you were a sister, I brought you along instead!

That was quite a mess you made of your meal, though! Well... don't worry, it's always like that at first!

A red horn. The strength to break boulders. A creature incompatible with humanity.

We eat humans, and they fear and hate us in return.

That's how it works.
