Kei no Haha

The mother of protagonist Yōkei, she bears a striking physical resemblance to her son. Known for her exceptionally upbeat and laid-back nature, she casually brushes off her son's memory loss as merely a "rebellious phase" or a sign that he has simply gotten dimmer. Even as Kei, in his defiant stage, calls her "old lady," she remains unfazed and gleefully involves herself in his life—an energetic, unconventional parent who plays by her own rules.
