Kyuuta Amanatsu

Amanatsu is Hina's next door neighbor who coincidentally is the real life lookalike of her favorite anime character, Mao, but with a completely different personality! He has a sharp tongue and frequently makes fun of Hina for being an 'anime otaku' yet can't help but worry for her and frequently finds himself running to her aid whenever she's in need. Amanatsu is a human who is targeted by all vampires for his sweet smelling blood.
