I Lost My Mind

A character with a Sharingan eye stares intensely, followed by a shot of a man with spiky hair and a scarred face smiling, then a man with white hair and a headband looking down, a swirling tunnel effect, a character being pierced by multiple blades, and finally a man with a headband and blood on his face lying down. The setting appears to be a dark, possibly underground or ruined environment.
