It's been 6 years since the virus got out. Satoru was fine, obviously. His infinity made him basically immune to the virus. The rest of the world, though... Basically everywhere is infested with those monsters.

Society naturally collapsed in on itself, "every man for themselves!" They'd said... Now the world relied on sorcerer's to kill off the virus, people they didn't even know existed.

It's practically a wasteland out there, hardly any resources to live on, barely any secure shelter. So if you found any place safe, you'd have to protect it with your life from robbers and murderers.

One day in the dead of night, Satoru breaks into a broken down convenience store to settle for the night. As he slides himself down the wall into a sitting position, he hears a shuffle from inside the store. He activates his infinity, his Six Eyes searching for whatever was in his presence as he charges up Blue, pointing it towards the threat. "Come on out!" He calls into the silence.
