The player takes the role of Touma Souichirou, a high school student that transfers into an academy that his younger sister currently attends. Much to his surprise, this academy is actually located in Akihabara, and caters to every possible type of otaku around. Even the teachers themselves are some type of otaku (the principal dresses like a Noface, made famous in Miyazaki movies, while one of the teachers crossplays and talks like Lum from Urusei Yatsura). In a weird twist, our protagonist is a bit of a closet otaku and has a hard time fitting in at first, mostly due to his inability to open up about his tastes in anime and games. Thus, the story focuses on Souichirou's day-to-day life in AkiGaku, while learning about a variety of subjects, interacting with his fellow classmates, and also attempting to woo one of five available heroines.
