Why not? Is it because Sakura is stupid and bad at killing?

You're here.

Do you like me~?! Then, can't Sakura and Oji-san become a family? ☺︎

Why do you work here, Oji-san? Where is your home? The outside world?

I used to live in the outside world, but now I mostly live here.

Three strokes here.

I don't think so. When I went back, there was nothing left.

Aren't there a lot of fun things to do outside? Aren't you lonely not being able to see your family?

That's not it.

But you absolutely won't say you want to kill people around others, especially in front of adults. You are a kind child.

Since you've been outside, do you have a family, Oji-san? Don't you want to go back outside?

You're not stupid, Sakura. You've learned how to write many kanji and do arithmetic. You're also good at origami, drawing, and shooting.

Sakura, your family must be people that understand your true value.

I'll find it for you. Your new life.
