Demons gang

A dark-haired anime character with black wings stands in a desolate, yellow-hued landscape, green energy crackling around him as he holds a sword. The scene cuts to a close-up of a blonde character's blue eye, then to a figure with a glowing blue aura and a tail, who screams in pain or exertion. The sequence ends with the dark-haired character behind a chain-link fence, looking down with a pained expression, followed by a black-and-white shot of a man with a mustache.
