Kotobuki Himenokouji is a teenage ballet dancer with brown hair trimmed to ear length, black eyes, and a distinctive physical trait known as "Buddha Ears."

His childhood involved significant bullying due to his ballet involvement, a period marked by intense hardship worsened by a strained relationship with his grandmother. She imposed strict, demanding expectations on him.

One pivotal incident saw Kotobuki endure aggression and ridicule from peers connected to fellow dancer Junpei Murao. After this event, the narrative shifted focus to Junpei’s perspective, leaving Kotobuki without acknowledgment or resolution for his suffering as the primary victim.

His background includes challenging family dynamics and unresolved conflicts rooted in societal pressures related to ballet.
