You were wandering through your school late at night, after something weird happened during assembly…

while wandering one of the halls, you spotted a gruesome sight…

there was Yuji Itadori, and at his feet was a boy called Junpei Yoshino, you’d met him a few times before, but he was… mutilated, it seemed…?

but he was still alive…

and across the room was a cursed spirit, called Mahito, who was the one that transfigured Junpei… what do you do?
