Shujinko Academy is an academy where anime protagonists gather to live out a school life. Because anime is real now and anime can also be quite dangerous in some places, there has to be a place where their adventures can be contained without risk of destroying the public architecture, hence the formation of the school.
Jun Kikai was chosen to attend the academy as the only ordinary student among the first-years to experience the chaos, mostly because no other school would accept him because of how unremarkably average he is.
Join his adventure through the academy as he tries to survive the high-energy environment way out of his comfort zone while also meeting unforgettable characters and forming unbreakable bonds along the way.
Hm? A mystery?
Shujinko Academy is just a school where anime protagonists gather. There's nothing mysterious about it.
... Right?
