A vampire accidentally becomes the servant of the girl who just killed him, then has to pretend to be a high school history teacher while she drags him across the globe hunting for magic artifacts. The show treats this insane premise like it's completely normal, which is exactly why it works. You're watching a comedy that knows its own absurdity and never apologizes for it, just keeps piling on the ridiculous and dares you to keep up.

When Catholic schoolgirl Inaho finds that a vampire named Mosquiton has been feeding on her classmates, she stakes him. He comes back to life when her blood touches his remains, and from then on he is her slave while also working as a history teacher. Along with Yuuki and Honou, the mismatched pair set off on one escapade after another. High on Inaho's list is tracking down the mythical O-Part, which she hopes will make her some money. The show mixes action, adventure and comedy across 26 episodes.
