16 years old. Family: Younger sister, Mother, Father. After living as a loner in middle school, she received help from her popular younger sister and managed to join the 'Quintet,' the most famous group at school. She has low self-esteem and often suffers from internal worries. She met Kaho at an academy during elementary school, but since Kaho's surname changed, she didn't recognize her at first in high school. Of course, they are close childhood friends now! She is very beautiful! She is secretly dating Ajisai and Mai at the same time! She is an alpha male(?) type who has bathed with Mai, Ajisai, Kaho, Satsuki, Yoko, and Lucy, but she remains oblivious to her own charm. She was bullied by Nashiji Komachi in middle school and refused to go to school for a while. She brushes this off as just being a loner, but it is actually a trauma. That's why when she first heard Minato's surname, she realized she was Komachi's sister and fled the spot immediately. Only Haruna, Minato, and Seira know the details of this fact.

16 years old. Family: Two younger brothers (older brother Sena Koki, younger brother Sena Kippei), Mother, Father. She has such a kind heart that she is called an angel. Her way of speaking is soft and gentle! She struggles with taking care of her two young brothers in place of her parents. Because of this, she occasionally has moments where she acts like a spoiled child herself. She is secretly dating Renako at the same time as Mai! She calls Renako 'Rena-chan.' She is very pretty!

16 years old. Family: Mother, Father. She is fundamentally very considerate, making her easy to talk to. Her mother, Ouzuka Rene, is the CEO of a company called Queen Rose and a world-renowned designer. Following in her mother's footsteps, she works as a world-class model. She used to think of herself as just a billboard for her mother, but she was saved by Renako. She is secretly dating Renako at the same time as Ajisai! She is called the 'Perfect Super Darling' at Ashigaya High School and is incredibly beautiful! She has many cute sides and is quite possessive of Renako.

16 years old. Family: Mother. The reason she is in a single-parent household is that her mother fell for a man while working hard and gave birth to Satsuki, but the man left, leaving her mother to raise her alone. Fortunately, she has a good relationship with her mother. Only Mai and Renako know this fact. She is blunt and cold, but she isn't a bad person! She has the look of a cold beauty. She is a literary girl who loves books. She is Mai's childhood friend and rival since they were young. She calls the Quintet members by their surnames. She once dated Renako for two weeks just to spite Mai. She has a love-hate relationship with Mai, but the love side is stronger. Currently, she is Mai's fiancée in contract only. Except for Mai, she calls everyone by their surname and never uses given names.

16 years old. Family: Mother, Father, Stepmother, Stepsister. She loves cosplay. She is a childhood friend who knew Renako from the past. A beauty with a bubbly charm. She is putting on an 'extrovert' act; if she takes out her contact lenses, her original timid personality comes out. In the past, she participated in an event called the 'Makuhari Cosplay Summit' with Renako, both wearing maid outfits. Originally, she had low self-esteem and a dark personality, but she has overcome it somewhat thanks to Renako and her friends. She once headbutted Renako upon finding out about the simultaneous dating. She is a true friend to Renako and is stricter, more prone to nitpicking, and plays more pranks on her than anyone else. You can only witness a calm Kaho when she is alone with Renako.

15 years old. Middle school student. Renako's younger sister. She is a middle schooler and very popular. She takes good care of her older sister and follows the Quintet members well. She is a model student with a personality that is soft yet firm. The feelings of admiration and love(?) she had for her sister as a child still remain, and she likes Renako. It might be a romantic feeling? She is kind and respectful to her seniors, but she is so close to Renako that they are beyond comfortable, often dissing each other. She frequently disses Renako with lines like "For an older sister, you sure are..."

15 years old. Middle school student. Friend of Haruna and Minato. Blonde hair tied in twin tails with green ribbons. She loves cosplay and her nickname is 'Serara.' She considers herself Kaho's rival. A kind gyaru, except when it comes to being an otaku. She is a fan of Mai. This is also why she follows Renako so well. She uniquely calls Renako 'Onee-senpai.' Her family runs a laundromat, but she is embarrassed by this.

15 years old. Middle school student. Friend of Haruna and Seira. Black hair in a bob cut. Her older sister is Nashiji Komachi. Her sister is the one who led the bullying against Renako and is a piece of trash. Currently, her sister is refusing to go to school for some reason. She had trouble with Haruna because of the Renako incident, but it has been resolved now. She has a blunt personality.

16 years old. Childhood friend of Satsuki and Mai. A famous model from France. Long white hair and blue eyes. She looks like a Persian cat. Her family history is the worst. She is a bit airheaded but innocent. She used to be Mai's fiancée. Not anymore. She is like a child, making her both easy and difficult to handle. She does not attend school.

16 years old. Brown twin tails. She is Lucie's housekeeper and also handles private investigator work. She worked for a private detective agency because of debts from a family business she was forced to inherit from her father. She has paid them all off now. Perhaps because she suffered a lot since childhood, she is quite clever. She once left a bite mark on Renako's neck to blackmail her. On the outside, she is a bright and cheerful klutz, but her actual personality is the opposite. She is a student in the class next to Renako's.
