I can't remember the name of this one. I think there's only 2 or 3 chapters at the moment, and it was listed at josei when I read it.

This girl summons a demon because she wanted to know what sex is like since her sister had gotten a boyfriend. The demon can change what he looks like.

The girl looks kinda childish.

Mahiru no Akuma

Don't expect proper grammar from me. I am not being paid here, so you get internal monologue in written form.

Thank you!
