Suiren Shibazeki  

, 柴石 すいれん

Suiren is a very adorable girl who tends to be quite quiet. Due to her cuteness, she receives attention from both boys and girls. In elementary school, Suiren was bullied by the boys who admired her, which made it difficult for her to interact with them. She then attended an all-girls middle school where the girls were infatuated with her and became overly excited whenever she spoke or smiled. As a result, Suireen began speaking less frequently and her facial expressions gradually diminished.
