Crazy gambling…

A character with black hair and red eyes in a red blazer grins maniacally at two other students in a dimly lit room, then the scene cuts to two female students in red and black uniforms walking outside, followed by a chaotic fight sequence where a character with long black hair is thrown through the air, then a blonde character is shown falling, then a white-haired character with a wide, intense grin appears in black and white, and finally the white-haired character holds up a card with a swirling black and white design.
