Former High Schools

In Danganronpa: Trigger Happy Havoc, it is stipulated that to be considered for recruitment to Hope's Peak Academy, a student must already be attending high school. This rule also carried over to Danganronpa 2: Goodbye Despair, and to the Ultimate Academy for Gifted Juveniles featured in Danganronpa V3: Killing Harmony. Although the students' former schools are never mentioned by name in-game, the schools were revealed in the games' associated art-books, and school emblems can be seen incorporated into most characters' designs.
