Blood Lad: Wagahai wa Neko de wa Nai

On their way to demon world Acropolis, Fuyumi has to consume Staz's blood once again to avoid disappearing and starts to become addicted to it. Meanwhile, a misguided vampire hunter group, calling themselves Team Fearless, targets Staz. While the vampire initially fights against them on equal footing, mid-combat he loses his ability to heal himself after being hit by a weapon made of silver... and Fuyumi is kidnapped. Ignoring his weakened state, Staz heads for Team Fearless' headquarters.
