Inu x Boku ss

A dark, viscous substance spreads across a light surface, followed by a hand in a white glove gripping a pistol, then a close-up of a character with a white face and dark hair, then a character in a white outfit with a red mark on their chest falling backward, then two characters in white outfits with large feathered wings clashing in front of a cherry blossom tree, and finally a close-up of a white, stringy substance dripping from a purple object.
