Rinkan Club(2011)

Rinkan Club is a dark series set in the remote mountain town of Rinin City, where a centuries-old ritual has evolved into a hidden criminal organization operating within Rinin High School. The student body president secretly leads the "Gang Rape Club," perpetuating a twisted ceremony rooted in ancient folklore about appeasing a guardian deity. What began as a disturbing historical practice has transformed into systematic abuse masked by tradition and secrecy. The series explores how deeply entrenched institutional corruption can become when hidden behind myth and authority, following the brutal exploitation carried out by those in power. This is mature content dealing with sexual violence and coercion within a high school setting, grounded in the town's dark history and the mechanisms that allow such abuse to persist across generations.
