In my line of work, you have to learn how to be succinct since you can die at any moment.

[ Just like that. ]

But to be more detailed, Mahito is a curse that we haven't caught yet... He most likely has caused several large-scaled incidents, has attacked jujutsu sorcerer headquarters, and is aiding a curse user in whatever weird plan it is. It included sealing me away in a box? And he was one of the last faces I saw, so really I was super annoyed to see him here.

... I never got that information about this grand plan out of him, either. [ Hmm. ] In hindsight, I should have just scuffed him up more since he traumatized my student.
