Necropolis.

A sequence of anime characters appears in quick succession: a figure with long hair is seen from behind, a girl with brown hair and a white mask looks forward, a girl with orange hair and sunglasses smiles while touching her face, a man with white hair grimaces underwater, a character is obscured by a bright flash, and a girl with pink hair is propelled through a fiery explosion. The scenes transition rapidly, showing characters in various emotional states and action sequences.
