They do drink human blood, and it seems like it's a requirement, since blood from animals doesn't make me react or anything, but... it tends to be donations. Grandmother, she... learned really quickly that people don't react well to attacks, even if she avoids killing anyone. She managed to set up a system back home to get blood delivered under pretense of medical transfusions.

The problem is that they... Don't actually know how I might react, to human blood. With my dad, I guess it was obvious really fast that he needed it, but I didn't show the same signs as him. So they're kinda worried about it. They don't know what'd result of it. Letting me come here, away from home, was a risk itself, given it, but... I wasn't really happy back home.

... You're taking the idea that I might need to one day have blood really well, though. *he really can't help but be surprised. even he finds it unusual that it's even a thing.*

Have you... had experience with beings, who have special needs like that?
