Kokichi is a slim young man with light peach skin and sharp brown eyes. He had black hair tied into a top knot above his head and following his healing at the hands of Mahito's Idle Transfiguration, Kokichi obtained a healthy body. Only a single scar on his cheek remained and he was able to stand up on his own. Like his Mechamaru stand-in at school, Kokichi dons a normal jujutsu high uniform with a white puffy scarf-like cloth around the collar of it.
