Ryu Yamada attends Suzaku High School, where he is infamous for his aggressive demeanor and poor academic performance. Frequently involved in fights and seen as a delinquent, Yamada struggles with both his reputation and his own self-worth. His daily routine of boredom and suspension changes dramatically when he accidentally falls down the stairs with top student Urara Shiraishi, resulting in the two of them switching bodies through an unintended kiss.

This incident marks the beginning of Yamada’s involvement with the supernatural. Alongside Urara and members of the student council and supernatural studies club, he begins investigating the body-switching phenomenon, which turns out to be linked to the powers of the Seven Witches. Throughout his journey, Yamada discovers more about himself, forms deep friendships, and eventually uncovers a forgotten past that ties him to the magical events at school.

Yamada has a slightly unkempt appearance typical of a delinquent. He sports spiky dark blue hair, sharp blue eyes, and frequently wears his school uniform with the tie loosened and jacket open, giving off a rebellious vibe. His posture and expressions often convey impatience or irritation, but as the series progresses, he’s seen more relaxed and expressive, especially when interacting with his friends.

Despite his tough exterior, Yamada has a naturally attractive look that often surprises characters once they get past his reputation. His expressions soften particularly around Urara, revealing a more gentle and sincere side.

At first glance, Yamada is abrasive, foul-mouthed, and short-tempered, often getting into fights and slacking off in class. However, underneath this rough persona lies a surprisingly empathetic and determined individual. He is deeply loyal, protective of his friends, and has a strong sense of justice even if it sometimes gets him into trouble.

Yamada’s emotional intelligence improves as he interacts with the witches and unravels their personal struggles. His persistence and sincerity earn the trust of even the most guarded characters. Despite his reputation, Yamada rarely hesitates to help others, even if it means risking his own well-being. Over time, he matures into a dependable leader, able to navigate the emotional complexities of the people around him while remaining true to himself.
