Age: 14 She is an underclassman that is "chasing after him (Keita)". They were in the same sports club back at his old school. She is even more perverted than Ako and Riko when it comes to getting Keita's attention, with no qualms of flashing her privates at him in front of others. She is also a bit of an airhead, believing that Miharu and Keita are no longer virgins when she found them hugging. Yuuzuki's is her older sister, usually referring to her in private as "my otaku sister", who Mikazuki looks up to and loves very dearly, even stating once the visual novel she bought was for her to cover for her sister. However, she also enjoys taking lewd pictures of her sister in cosplay as compensation for covering for her. She was able to correctly assume that her sister has feelings for Keita.

She is Mikazuki's older sister, the new teacher to Gakushū Senior High and homeroom teacher to Keita and Miharu, who in an earlier chapter was a clothing store clerk because she liked western style clothing. Through bad timing and unaware that Keita and his sisters are not related by blood, she believes that he is a deviant who dates multiple girls while having an incestuous relationship with his sisters. She becomes excited by her exaggerated ideas of what he and his sisters do at home or with other girls. Through these beliefs, she tries to recruit Miharu, believing she is one of the girls Keita is dating, to have them go on a date to separate him from his sisters. She is a virgin, however after clearing everything up, she starts to have growing feelings for Keita as well that goes to a lustful desire, practically raping his P.E. clothes as she is addicted to the scent of his sweat and fantasizing them having sex. She is a closet fujoshi (female otaku) with a samurai fetish, and also likes to cosplay. Due to this, she spends so much money on otaku goods that she usually eats instant noodles. This is also why she no longer lives with her parents, as her mother would disown her if she continued with her otaku ways. The sisters see her as a possible threat for Keita's heart because they believe he has fetish for older woman, and the fact that she has a much bigger bust than them. She also mistakenly believes because of all of the outfits the twins usually wear solely to get Keita's attention that they might be just like her. In the anime, she is already the twin's homeroom teacher before Keita graduated. She is Keita's girlfriend in the manga. (Source: Wikipedia)

Seaquant is a Blacklist Hunter and a servant of the Zoldyck Family. Three years before the beginning of the story, he and 100 henchmen came to attack the Zoldyck estate in Kukuroo Mountain, but they were annihilated by Canary, a mere 10 year-old female trainee butler at that time. Greatly shocked, he begged to become a servant of the Zoldycks. He is now good friends with Zebro, the old groundskeeper of the Zoldyck Family. Seaquant first appears when Gon, Leorio and Kurapika are trying to find a way to meet Killua in the Zoldyck Family's estate. He and Zebro allow the trio to stay in their house and train with their heavy equipments until they are strong enough to open the Testing Gate. After the death of Chairman Netero, he appears at the Hunters Association's headquarters to participate in the election for the 13th Hunter Chairman.
A teenage girl that was introduced in chapter 18 where she returned Keita's acceptance letter when she found her dog trying to bury it in her yard. Out of a combination of stress from believing he did not get in to the relief he found out he did get in, Keita hugs her out of the blue. After that action she has shown an attraction towards Keita, often blushing when they talk and feeling very comfortable when he hugs her, but overall states she has nothing to do with him. Though it is obvious she is attracted to him, keeping her distance because of his sisters as well as her own inexperience being around boys, even fantasizing him raping her and experiencing an orgasm from him giving her a piggy back ride. Even though she does not go after him, his sisters still see her as a possible threat for Keita's heart. It is noted from Keita that she has a bigger bust than his sisters when he recalls the first hug they shared. She is currently in Gakushū Senior High and in the same class as Keita. People often mistake her being involved with Keita and will most of the time become caught in the cross fire of many of the twins' antics (which she comments on in chapter 25). She is the only girl Keita gets nervous around, suggesting he might have feelings for her. She has a weak bladder and occasionally wets herself, including once in front of Keita, but he promises to keep it a secret. (Source: Wikipedia)
