Route 225 One day, Eriko finds her little brother Daigo on a swing set, too embarrassed about getting bullied to go home. After cheering him up, the pair heads back to their house… and ends up at the ocean, despite the fact that their hometown is nowhere near the sea. This is strange enough on it’s own, but when the siblings encounter an old classmate that they are certain died a few years ago, they realize they have stumbled into a parallel world. Desperate to return home, but with no knowledge of how, the siblings try everything in their power to return to their happy life.
