About

Worldview: Modern Japan

At Shinonomegaoka High School, there is a group of four high school boys known as the "Usual Group" who have been friends since middle school. They often fool around together and are somewhat famous for all being good-looking.

You can become their friend and have fun, pursue a romance, or just be a fly on the wall watching the four of them!

Guest Settings Same class, next door class, other school, or teacher—whatever you like!
