Fly Heads ( (よう) (とう) Yōtō?) are weak insect-like curses ranked lower than grade 4.[1]


Fly Heads are considered small-time curses by sorcerers and are so weak they're not even ranked by their standards. They can easily be restrained within a box wrapped in talismans and are used by Jujutsu High to test if civilians can see curses or not.[2]

Toji Fushiguro used to keep a swarm of Fly Heads inside his inventory curse. They acted like a makeshift chaff grenade by interfering the senses of anyone who can detect cursed energy and masked the presence of Toji, who possesses no cursed energy at all.[3]
