Taro Sado (砂戸 太郎 Sado Tarō?)
Voiced by: Chihiro Suzuki (drama CD), Jun Fukuyama (Anime)
Taro Sado is the hero of the story, and a true masochist. He went to the same middle school as Yūno, who is at fault for turning him into a masochist. He is not sexually attracted to his relatives, though his mother and older sister are attracted to him and have an over-protective relationship for him. He is sometimes forced to perform cross-dressing (in the anime he was tumawid dressing because he was hypnotized sa pamamagitan ng Mio, and fell in pag-ibig with Tatsukichi, who tries to avoid Taro sa pamamagitan ng tumawid dressing). Taro is known to have a ridiculous amount of "Pervert Energy" (over 30,000 units, compared to 5 units for average people) which was employed sa pamamagitan ng Noa in one of her schemes. Despite the fact that he is a self-proclaimed "Super Masochist", Taro will not hesitate to help out his mga kaibigan such as rushing Mio to a hospital when she collapsed during their mock-wedding on their date, trying to beat up the senior who attempted to sexually assault Arashiko way back despite being outmatched, acknowledging Tatsukichi's cross-dressing and telling him that he does not mind. His first halik was with Mio. His surname Sado is probably a pun on sadomasochism which is particularly displayed in a wide array of scenarios throughout the series.
Mio Isurugi (石動 美緒 Isurugi Mio?)
Voiced by: Chihiro Ishiguro (drama CD), Ayana Taketatsu (Anime)
Isurugi is Taro Sado's senior. She is the head of his school club and is violent to Taro due to her superiority complex. She is a self-proclaimed deity. She also has ailurophobia. There is an implication that she has feelings for Taro (as a result of his kindness towards her, plus the fact that he treats her just as he does everybody else), although she does not admit to them. An episode suggested she is jealous when another girl makes advances towards Taro as in the case of her being madami violent towards him when Noa gave him a mound of lilacs. She is an extreme tsundere, and repeatedly attacks Taro, in an (unsuccessful) attempt to cure his masochism. She seems to be unaware of the fact that she has developed an attachment towards Taro, nor the fact that she has unconsciously developed feelings towards him, and constantly denies these facts whenever Arashiko has pointed it out. Her first halik was with Taro.
Mio does not get along well with Tatsukichi when his alter-ego surfaces while cross-dressing, especially from the fact that Tatsukichi belittles Mio's bust size whenever his alter-ego comes out. She does not quite realize that she has an innate sadistic personality, which may explain why she constantly resorts to violent measures to cure his masochism. She is shown to be very athletic, but has been sinabi sa pamamagitan ng Arashiko to not be very good at studies.

She occasionally gets into situations where she briefly forgets her androphobia in her eagerness to get closer to Taro (or is accidentally touched sa pamamagitan ng him), and when she actually realizes what happens, she comically assaults Taro who, due to his masochism, enjoys it.

Voiced by: Rina Satō
Hayama is Taro Sado's classmate and close friend. He enjoys cross-dressing (which induces his female alter-ego to appear).

His alter-ego, "Tatsumi Antoinette XVI," has superiority complex while he is cross-dressing, and repeatedly argues with Isurugi (sometimes over Taro's affection) as well as repeatedly attacking verbally Mio's breast size.
