Sakahir

A muscular man with a long white braid crouches in a dimly lit, underwater environment, then the scene shifts to a figure running toward a massive, radiant purple energy formation. Another character with spiky white hair and a black mark on his face appears in a close-up, followed by a view of a character's back as they move forward, and finally a low-angle shot of a figure's legs in a dark, purple-hued setting.
