The Mr. Vamp is a Vampire

“Mr. Vamp,” an immortal vampire, has had a number of careers over his long life. To mix things up, he's now working as a history teacher in a high school in Japan. He thinks he's got everyone fooled into believing he's just an ordinary mortal, but due to a lack of effort on his part when it comes to truly blending in, the students and teachers all realize his true nature (but still humor him by going along with the fiction). Hijinks ensue! (Source: Kodansha USA)
