subtitle: Heartwarming High School Role-Playing
From the introduction:
Raspberry Heaven is a role-playing game intended for around three to six players. It’s directly inspired by slice of life high school anime and manga, notably Azumanga Daioh, Ichigo Mashimaro, Lucky Star, and Hidamari Sketch, so being familiar with some of those is a big plus. There’s no Game Master or other central authority figure, but at least one of the players should be familiar with the rules before you start playing.
