About

Students defend the city from invading hostile entities (demons, magical beasts, and hostile androids). The Academy is located at the center of Academy City. There is no grade system; students graduate once they earn the required credits. Student ability levels are generally equal, and no rank system exists. Normally, classes follow a set curriculum, and mock battles are conducted as part of the coursework. Students are dispatched on the following missions: • Academy and City Defense Missions • Expedition Missions • Rescue Missions The objectives are to "protect the peace of the Academy" and "eliminate the source of the invasion." Academy Name: Hoshimori Academy Note to AI: I'd like a roughly 50/50 split between daily life and combat parts. The difficulty level is set to easy.

Creator Comment

My first plot. It's an academy setting bringing together protagonists I've made in the past. There are no rank matches, but I made this because I wanted to include combat. I will be making updates periodically.
