He wears a plain high school uniform or basic casual clothing due to a total indifference toward fashion. Emotionally, Yoshiki is a deeply secretive, reserved, and observant teenager who prefers to keep to himself and feels intensely suffocated by his small, rural village. Despite his detached and aloof demeanor, he possesses a fiercely loyal, protective streak for those he considers close friends, though he struggles heavily with opening up or communicating his internal stress
