Kokichi Muta (与むた 幸こう吉きち, Muta Kōkichi?) is a supporting character in the Jujutsu Kaisen series. He was a second-year at Kyoto Jujutsu High using Ultimate Mechamaru as his proxy to attend school. Kokichi himself could not due to the sickly and fragile body he was born with as a result of his Heavenly Restriction. 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.
