A 3rd year high school student at Rinin High School who is the Student Council President and the leader of the Rinkan Club. Motoko, like Suzuko, was born as a result of one of the Rinkan Club's "ceremonies" and is thus treated like a treasure by her hometown. She has cold, yet charismatic demeanor, resulting in her having very few friends, but allow to have a commanding presence with both the Student Council and Rinkan Club. She enjoys watching the maidens suffer, especially when it's her greatest enemy; Suzuko. She's cool and keeps her calm in most situations but sometimes reveals a little too much information, leading to her downfall. She became the student council president in charge of the Rinkan Club in order to prevent becoming a maiden herself. In the OVA, she is in love with her best friend, Maki.
Rinkan Club
The main character is a senior who attends Rinin High School; the only school among the mountain town of Rinin City. The main character, who is the student president of the high school, has another hidden persona. The persona as head of the “Gang Rape Club”... A dark ceremony existed that had been handed down for thousands of years in the old town of Rinin; the name of the ceremony, in particular, in the oldest of records. That ceremony, enacted to protect the region from disease and crop failure as a curse from the region's guardian deity, Hime Iwanaga, occurs in the evenings between the new moon and full moon, in which a maiden is disguised as Konohanasakuyabime and gangraped to appease Hime Iwanaga's anger. In regards to the maiden, there must be an important man participating in the gang rape, in other words, that man must be related in blood to their wife or lover, mother or daughter, younger sister or older sister, and the like, and after the gang rape, if a pregnancy occurs, Hime Iwanaga's anger is abated, and a good harvest and safety upon the region will be promised. However, if a pregnancy does not occur for the sake of suppressing Hime Iwanaga's anger, the maiden is supposed to be covered with semen, and floated down the river alive, as a sacrifice. And now---After the Tashio era, the ceremony itself had vanished into the dark history, but had still continued on at Rinin High School; the cruel, improper traditions being inherited over into a secret society through actions carried out by the Gang Rape Club. For generations, the student president of the High School has served as the head of the Gang Rape Club, not allowing even one day to pass uneventfully, submerging numerous women to the dark, suffocating pleasure.
