The brothers receive a strange note about Naoto's future that brings up the upheaval that Shouko briefly talked to them about.
Naoya and Naoto catch up to the man messing around with their memories and figure out that he was the same person controlling Masayuki and his mother.

Both brothers, along with Mikuriya, slowly make there way away from the watched area. It's not easy though- the enemy's power is so overwhelming that Naoya can barely go any further.
