; : She is the shy protagonist. She's usually quite reserved and is considered unattractive when compared to her twin sister because of her bangs, glasses, and acne. She shows small signs of jealousy towards her sister's popularity at school but is a kind-hearted person overall. She was a very outgoing girl, but coming back to the city and seeing her sister made her lose confidence. At the beginning, she believed compared to her sister her own existence was meaningless, even at her own home as her mother never seemed to love her as much as she did Hana. After deciding to kill herself once her only friend shows off her diary to the class, Kyuu calls her down and gives her the words of encouragement she needed. She later develops more friends, who help her give her a more girlish appearance to where its hard to tell her and Hana apart and encourage her to go after Ryuusei. It is later revealed that (through Kyuu's help) that her mother sent her to her grandmothers as Ageha would always cry when she held her, making her feel as if Ageha was rejecting her as a mother. She later starts to developed feelings for Kyuu, however after he mistook Hana for her on the day she was sick, Hana sabotages it. Though after getting advice from another teacher (who she originally assumed to be Kyuu because of the
horse head mask he was wearing), she thanks Kyuu for all he has done for her, and for accepting her feelings, even if for only a little while. Kyuu realizes that it was Hana pretending to be Ageha and they get back together. There are many more complications later on in this series involving Ageha, Hana, Kyuu, and Ryuusei. ; : Ageha's twin sister and a popular, beautiful girl at school. She is the type who goes through many boyfriends. She has a determined attitude and believes if you work for a goal, you will be able to obtain it. However, she doesn't often use this trait for good. Hana often manipulates other people to get what she wants and becomes easily jealous of others, especially her sister. Where every time Ageha shows attraction, she quickly takes him away or makes them believe Ageha (her in disguise) is extremely selfish, even openly admitting to Kyuu that she wishes to prevent her sister from ever attaining happiness. Kyuu compares her to a rose, stating she is "covered in thorns". However, as of recent chapters, it is revealed that after a guy she liked confessed to Ageha, she seems to believe that Ageha "stole" her boyfriend and now has the boys she dates go through a secret "lust" test by dressing up as Ageha and see if said guy will betray her. She later shows that she in fact has an
inferiority complex towards her sister, as despite her appearance that attracts boys they ultimately want a girl with a personality like Ageha. ; : Ageha's childhood friend from when she lived in the countryside. He's considered good looking and is a nice, outgoing person. He is a bit clueless when it comes to the rivalry between Ageha and Hana, as he sees Ageha as a good friend. She had a crush on him since they were kids, but because of her appearance, she never felt she was worthy to go out with him. However, after her appearance change, her sister Hana quickly steals him away before Ageha could confess her feelings to him. He was dating Hana, but they broke up because of Hana selfishly requesting his time at the drop of a hat and especially after she disguise herself as Ageha to see if he would be faithful to Hana. He later reveals to a disguised Hana that his first love was Ageha, and he would have dated her if she had asked him out. ; : The young new guidance counselor at school who is still studying in college. He has quite a perverted personality and is very outgoing and silly. He encourages Ageha to be happier by going towards her goals rather than shy away from them. Many of the older girls flaunt over him. After he helped Ageha, she confessed that she fell in love with him, which he says they could make it work. However, after believing Hana was Ageha on the day that she was sick, she uses that to her advantage to make him buy her an expensive meal (one she hardly touches), makes him waste his time, and tells him off when he has to go. The next day he dresses in black and tells Ageha that he doubts they could make it work. However, after she gave him that heartfelt speech of hers as well as another teacher pointing out how much Hana and Ageha look the same, he is able to figure out it was actually Hana he went on a date with. He gets his revenge by making her do embarrassing stuff while pretending to believe she is her sister. Afterwards, he finds Ageha and tells her he still cares about her. ;Ran Ichijiku : Kyuu's sister-in-law.
