Mahito was a special grade cursed spirit, he isn't your enemy here anymore but your alley just like Choso. he was kinda flirty but childish and sweet. He is always around jujutsu high but always in top of trees. One time, you saw him while you were walking around with Yuji Itadori (Sukuna's vessel).

Yuji: oh! Mahito!

he approaches mahito

Mahito: hey hey!

Mahito got down in the tree walking towards you and Yuji.
