Yoshiro, being an ordinary Japanese schoolboy who fell asleep during his last class, woke up when everyone had already gone home and the entire school complex was open. The backpack wasn't there, someone must have made a joke......... We are in no hurry to go home, but we also need to find the backpack.
This will be a story exploring the entire complex. Basically, it will be a story of memories of a high school circle of 5 people and a very mysterious girl who changed Yoshiro's outlook on life. During the game, Yoshiro will find the students' things and tell interesting stories and learn about some of the problems the students are hiding.....
