Otometachibana, Rinon

乙女橘りのん

She is an infamous delinquent at Tougetsu High School, where she is known as "Bear Killer Rinon." She led a group of fellow delinquents dressed in furry attire to cause chaos at school and to challenge Honoka to a fight, believing he had done many bad things to the former student council president (unaware that she was being tricked by him). However, Kagari, along with the Ivory Quintet, intervened and defeated her.
She is also a workshop witch who answers only to Kazane.
In the manga, she bleeds from the scar on her forehead when she gets angry.
