Sumiko Sumimura

Sumiko Sumimura is a skilled kekkaishi who lacks the status of a Legitimate Successor. She maintains a detached, highly logical, and occasionally unsettling demeanor. The daughter of Shigemori Sumimura and wife to Shuji, she is the mother of Masamori, Yoshimori, and Toshimori. While her cold personality and perceived absence often lead others to label her a poor mother, her brothers remain fiercely defensive against such insults, even as she tends to intentionally provoke discomfort in those around her.
