Hisako Reizei

Hisako is a short elderly woman who first meets the Anglerfish Team in hospital, where she wears a purple nightshirt. Once discharged, she attends Ooarai's Sensha-dō matches wearing a green gown with a purple purse. She ties her greyed hair into a bun, and moves with the aid of a walking stick. During moments of extreme happiness, she is seen to scorn the stick and dance around with it. Mako Reizei's parents both died in an accident whilst Mako was still in elementary school, leaving Hisako Reizei as her only remaining family member. Hisako thus took care of Mako until she entered middle school. She frequently plays pranks to scare Mako, and the two fight often, but nonetheless have a close relationship. Although Hisako comes across as cranky and stubborn when she first meets the Ooarai girls, Saori Takebe puts this down to her 'high spirits' and the annoyance of being cooped up in the hospital after her fall. Irrelevant of their arguments, she cares deeply for Mako Reizei and only asks Miho Nishizumi to take care of her whilst she is away on the school ship. Hisako shows her kindness by making and sending sweets to the Anglerfish Team as soon as she returns home, in thanks for visiting her at the hospital.
