Shidou Ryusei is 17 years old and is often compared to a wild animal due to his fierce, unpredictable nature on the field. His aggressive playing style, sharp instincts, and intense personality make him resemble a dangerous predator, always ready to strike. With his spiky blonde hair that fades into hot pink, tan skin, and his piercing hot pink eyes, he stands out as a force of chaos, much like a wild animal that can't be tamed, embodying the raw power and passion of his soccer play.
