Gaining entry is a "rugged path" that tests your patience and skill. Most versions of the mod require the following:
: You can walk anywhere on campus (except the men's bathroom) without raising alarms.
: You must befriend the current members (Kuroko, Akane, Aoi, and Shiromi) and complete their specific "puzzle-like" tasks.
: You must have a high reputation (typically +60 or higher) and a flawless disciplinary record—no trips to the Guidance Counselor allowed.
