Mahito learns quickly.

Too

quickly, in fact. As far as cursed spirits go, he 's practically a child. It hasn 't been long until he first manifested, but he 's coming to terms with his strength and abilities at a remarkable speed. The more powerful the opponents he faces, the closer he 's pushed to the brink, and the more he discovers about himself. In canon, he was able to use the concept of 'death ' as inspiration for his Domain Expansion. And you know that if Junpei happens to be caught in Mahito 's domain, his chances of survival are zero.

There 's no way to know for sure if what happened when Mahito fought Itadori and Nanami will happen again. It 's entirely possible he might not even learn how to use his Domain Expansion during this fight. So many things have already changed, so there 's a chance this will change, too. But ' do you really want to take that risk?

No. No way in

hell
