Blood Lad

The second Twilight almost happened, but the main character was eaten in time, lol.

This series needs a sequel, definitely

A vampire, a girl from the human world who has fallen into the world of demons. Something was painfully familiar, but it wasn't there. The guy is obsessed with anime culture, and the girl in the school uniform, it seemed that he was about to either rape or devour her. But as soon as she became a ghost, all his imaginary love disappeared. I'm glad I didn't eat it.

What a caring brother.
What a sweet little sister.
And I'm also sinning against my family, huh.

I'm going to spray a little here. :DDDD
