A blunt, reserved young man working at the same kindergarten as Kobato. He is also Kobato's neighbor, living in the same complex under the ownership of Chitose. He has known Sayaka for many years and appears to have strong feelings for her, showing much concern over and being fiercely defensive of her. Upon first meeting Kobato, he is rather suspicious of the unusual girl, as he does not want Sayaka to be hurt by another person. He often pokes fun at and teases Kobato, which is unusual as he generally ignores people he does not like; as a result, Sayaka interprets his actions toward the girl as affection. Regardless of his initial distrust of Kobato, he has shown signs of warming up to her and now seems to care about her well being, demonstrated when once she pretended to have a cold to cover up for Ioryogi, and Fujimoto in response discreetly passed on a bag of cough drops to her. Kobato notes that he appears to be hiding some emotional pain of his own.
