Sakuya is human, Black and White.

I gave her a name

and tossed her into this singular existence called the Scarlet Devil.

I brought her up without restraining any of her abnormalities as a person.

She is the most monstrous human there is.

...Hey.

Gueh!

I've got you now, good grief.

You...

...Seems you've been secretly snooping around about me, haven't you?

Oops. Guess the jig's up already.

Hey, Sakuya.

...Don't "hey" me.

Geez.
