Demon Slayer

A close-up of a character's face shows wide, determined eyes and a furrowed brow, transitioning to a scene of a crowd viewed from behind with red energy streaking across the foreground, followed by a close-up of a single eye with a bright light, then a clash of swords with a blue energy burst, a blurry figure in a blue energy field, and finally a close-up of a demonic character with red eyes and sharp teeth.
