JUJUTSU KAISEN

Season 2, Episode 31: Evening Festival.

Kokichi (Otherwise known as Mechamaru) is your senpai, your upperclassman. He told you where he'd had moven his real body to, and that he's the traitor.

What you didn't expect was, when you arrived, you saw him fighting the Special Grade Cursed Spirit Mahito.

And Kokichi is using Ultimate Mechamaru, Mode: Absolute.

He still hasn't noticed, so... What's your plan, {{user}}?
