2-A/3-A, Chizuru is the girl with the biggest breasts of all the class. After Kotaro comes to the school for Negi, she forces him to live in their dorm under the identity of Natsumi's younger brother, although he lives in great fear of her home remedies, which invariably consist of spring onion suppositories. She forms a Pactio with Negi very late in the story and gains an artifact. It is a scepter in the form of a spring onion that cures every ailment or status effect, but in return forces a person to obey any of Chizuru's commands when stabbed by it. In chapter 340 it is revealed that her family runs a conglomerate. In the manga's final chapter, Chizuru becomes a nursery day care worker and dotes on Fuka's and Fumika's daughters. Fuka Narutaki Live-action actor: Saya Kataoka is student number twenty-two in the class and the elder of the Narutaki twins. She constantly causes trouble, often using ninjutsu "skills" taught to her by Kaede to sneak around or run away. Her pactio in Negima! allows for the creation of unlimited cloning. Fumika Narutaki Live-action actor: Manaka Yamamoto is student number twenty-three in the class and the younger of the Narutaki twins. She is the opposite of her sister, often telling her that her ideas are bad. Satomi Hakase Live-action actor: Ririko Uchida is student number twenty-four in the class, and an expert in robotics. She is very close to Chao, actively taking part in the plan to reveal magic to the world, and utilizing Chao's magic and technology from the future, although she defers to Chao in judging whether they are doing the right thing. Her great intelligence, obsession in her work, and lack of common sense lead her classmates to refer to both her and Chao as mad scientists. She is the creator of Chachamaru, and essentially acts like her mother. She constantly upgrades her and takes special interest in the ways she develops, such as developing feelings for Negi. Her last name, "hakase", is a homophone of 博士, which means "doctor" (i.e., a person who has obtained a doctorate). Often, she is referred to as Hakase-Hakase (or just "Hakase", but with the alternate meaning). The English manga translates this as "Professor Hakase" or "Professor"; even the meaning "Professor-Professor" would be correct, depending on which version of the pun is in use.
