Hamano Chiharu
A student teacher who seems to have dated Ichinose in the past. She wants him back and sees Ai as her enemy. She looks like a cute little bunny but her personality is the exact opposite. She's Ai's very first enemy in trying to capture Sou's affections. She is extremely manipulative and will not stop at self-harm to get attention from Ichinose. (Source: Wikipedia)
