Clubs: Astronomy Club Blood type: A Hair: Brown Eyes: Blue Likes: Looking after others Dislikes: Loneliness She is a gentle, motherly, and loving, yet strange girl (she seems to have a problem with people calling her "old"). She is a kind person to everyone, volunteers at the daycare center in Mahora City and is in the Astronomy club. She is a good cook, and has exceptional domestic skills. Even though she is very nice, she can be sometimes be equally scary. Shortly after Golden Week, she found an injured dog on the side of the road. She took the dog in, which turned out to be a young half-demon boy named Kotaro Inugami, who had come to Mahora looking for Negi. Unfortunately, Graf Herrman, a powerful demon, attacked Kotaro, and kidnapped Chizuru when she stood up to him. She all but adopts Kotaro after Negi and Kotaro defeat Graf Hermann, and gets him to live in their dorm under the identity of Natsumi's younger brother. Chizuru is extremely courageous, as shown in her encounter and fight with Graf Hermann, where she calmly confronted him for his intrusion and even slapped him when he was about to petrify Kotaro. While Chizuru stays out of the fighting during the mock-battle at the festival, she does take part in the search for Chao late in the conflict, and wins a gift pack for finding her (which she promptly intimidates Kotaro and Natsumi into not disclosing). Her roommates are Ayaka, Natsumi, and Kotaro. Chizuru has the largest breasts in the class. In the Volume 8 character notes and the Negima Workshop, Ken Akamatsu mentions that Chizuru and Mutsumi Otohime from his earlier work, Love Hina, are very similar.
