Servamp (kuro)

A purple, bat-like creature with a long tail runs across a wooden floor, then the scene cuts to a silver-haired anime character lying on a green floor, followed by a close-up of him eating with chopsticks, then a close-up of his face, then him holding a white hat with a red band, and finally him with long, dark tendrils extending from his mouth, all in a dimly lit indoor setting.
