A young man with glasses and dark hair, wearing a black jacket, displays an excited expression with his hand near his chin, then the scene cuts to a wider view of a traditional Japanese restaurant where three young men are seated at a table, one with white hair eating, while the name "Ryuji" appears as text; the scene then shifts to a young man running across a stone path beside a body of water at night under a cloudy sky with a crescent moon.
