Koukichi Muta

Koukichi Muta is a Semi-Grade 1 sorcerer and a second-year student at Kyoto Jujutsu High. He attends school by controlling the cursed corpse Ultimate Mechamaru, as Muta was born with a sickly and fragile body due to a Heavenly Restriction. In exchange, he has a nearly boundless amount of cursed energy that spreads over a vast range.
