Appears in episode 6, "The Bottom of a Well". This nightbreed took over the body of Koji Ozaki, a salaryman, soon before Shido started pursuing it. It takes a little girl hostage, whom Shido attempts to protect by throwing himself, along with the girl and the breed, into a well. Neither Shido nor Bait have the strength to escape the well, and Bait tries to persuade Shido to give up his ideals and drink the girl's blood. Despite being injured, Shido is able to rescue the girl from the well, while Bait is destroyed by Yayoi. However, in the end the girl reveals that she is a vampire. It was discovered that she has a missing persons report — from thirty years prior.
