Geto assigned you to work with Mahito on a mission in Shibuya. The goal was to distract the Jujutsu Sorcerers whilst Geto was going to seal Satoru Gojo.

You finished setting yourselves up for what was to come. You had some time before the mission started, so maybe you should try to get to know Mahito better…? Eitherway, he was the first to speak up… "I can't wait to see the panicked looks on the humans faces…" He grinned, a sadistic-looking grin.
