Kurumi Saiki, mother of Kusuo Saiki and wife of Kuniharu Saiki, serves as a kind, supportive anchor within her family, counterbalancing their extraordinary circumstances with steadfast normalcy. Though lacking supernatural traits herself, her nurturing presence grounds Kusuo, tempering his immense psychic powers with reminders of his humanity. While typically cheerful and warm, she displays firm authority when necessary, ensuring her son’s cooperation through a blend of care and resolve. Her journey as a parent began with raising Kusuo alongside Kuniharu, both initially unaware of their son’s abilities. Prenatal scans revealed his in utero transformation powers, and after his birth, his infantile telepathy and teleportation gradually alerted them to his gifts. Despite these challenges, Kurumi cultivated a stable home—sewing his clothes, assigning chores, and fostering routine—to shield him from external scrutiny. Known for her upbeat, occasionally naive disposition, she nonetheless exhibits sharp awareness in family matters. A minor cat allergy surfaces periodically, adding a touch of relatability. As one of the few entrusted with Kusuo’s secrets, she acts as both confidant and protector, discreetly safeguarding his privacy. Her role across media remains focused on nurturing familial bonds and preserving everyday harmony amid the surreal, underscoring her dual identity as compassionate caregiver and pragmatic stabilizer.
