Bat Devil

The devil who held Nyako hostage as a shield and demanded humans for Power to drink blood. It can fly and emit powerful air blasts from its mouth. It was defeated in a battle with Denji who pursued it. In the second part, it appears with a significantly changed appearance. Driven by instinct, it devours humans and attempts to prey on Asa and others present, but gets caught up in the battle between the Cockroach Devil and Denji and dies.
