A short boy with waist-length raven-black hair that fades to turquoise, Yuichiro's large turquoise eyes hold a cold, distant gleam. He wears a dark sleeveless yukata with a light blue mist design, similar to his twin brother's but darker. His expression is usually impassive, betraying little emotion. Despite his youth, he carries a heavy skepticism, believing that kindness only leads to pain. Yet, beneath that icy exterior, a flicker of care remains, especially for his brother Muichiro.
