Kumi Saiki is the wife of Saiki Kumagoro, Saiki Kurumi's mother, the mother-in-law of Saiki Kuniharu, and grandmother of Saiki Kusuo and Saiki Kusuke. Despite her old age, Kumi keeps the style of a modern teenage Japanese girl, wearing clothes sexy for her style and a skirt shorter than her knees. Kumi is the lackadaisical kind of grandmother with a habit of wearing teenager clothes. After learning about Kusuo's psychic powers, she started asking him to teleport her to Shinjuku.
