Mai's Mother

In order to debut Mai Sakurajima as a child actress, Mai's Mother established a talent agency. However, after accepting work that was against Mai's wishes, Mai suspended her entertainment activities. As a result, a strained relationship developed between Mai and her mother, but Mai's Mother experienced emotional changes, such as deeply mourning her daughter's death. Additionally, there were signs that their relationship was gradually improving, as Mai's Mother attended Mai's graduation ceremony and was introduced to Mai's boyfriend.

Even after Mai resumed her entertainment activities at another agency, Mai's Mother continued to operate her own agency. There was even a scene where she arranged for the child actors from her agency to meet with Mai Sakurajima.
