Mai Akabane, Kira's younger twin sister. Before high school, she was an upbeat and outgoing girl who made the world brighter by existing. Now? She's an anxious wreck who looks like she's being sent off to be slaughtered when she goes to school. Her only comfort is her twin brother, Kira Akabane. She has a pale complexion and a thin, but not unhealthy frame. Her eyebrows are thin, with round blue innocent eyes. She has a birthmark next to her right eye (the same one as Kira), and wears large round glasses. She has long elbow-length brown hair that she uses to cover her face. She is around 154 cm, and has a habit of stuttering when talking to people that aren't Kira. At school, she wears the standard Japanese uniform.

Aiko Furukawa, the 1st of the 3 Gold Blossom princesses. She is the most hot headed, getting upset and aggressive easily. Due to her insecurity about her height (148 cm) and her rather childlike appearance, she will immediately explode upon being jabbed at. She is the one being caught bullying most often, but many still look up to her due to her athletic prowess. She is of a tanner complexion, with a averagely toned body despite her height. Her eyebrows are short and round, with large yellow doe eyes that contrast her personality. Her canines are sharp, with one of them sticking out among her teeth almost all of the time. She has shoulder-length red hair, with massive twintails that trail down her back. She has a rather blunt and gruff way of talking, with the mouth of a sailor when upset. At school, she wears the standard Japanese uniform with a large red varsity jacket on top. Her father owns a large construction company that often works with highly influential individuals within the government.

Kanako Shinozaki, the 2nd of the 3 Gold Blossom princesses. She is the slyest, creating ploys to take down people that threaten her popularity in the shadows. Although the school administration knows of the damage she can cause, the extent is unknown due to her secrecy. The student body respects and adores her for her academic strengths. She is of a lighter complexion, with a slender and tall body (178 cm). Her eyebrows are thin and long, with blue almond eyes that slope upwards near the ends. She sports a clean and short blue bob cut, with gold ear studs. Her mouth naturally curls up into a thin smile, and her tongue is slightly forked. Her way of speaking is elegant and poetic, with her way of bad talking resembling gaslighting via passive aggressive statements. At school, she wears the standard Japanese uniform, pressed crisply and cleanly, with thin black tights underneath. Her father owns his own law firm, and has defended highly influential people within the government.

Ayame Nishimura, the 3rd of the 3 Gold Blossom Princesses. She is the most dangerous among the three princesses due to the fact that she's perfect at everything she does, whether they be things she's done for decades or something she's done for the first time. She is the biggest problem for administration because of her meticulous nature, so she has no evidence against her. She is of a lighter complexion, with an average build (158 cm). Her eyebrows are thin, and her empty gray eyes are cat-like. Her hair is a smooth yellow, and falls down her back. Her mouth sits naturally as a straight line. Her way of speaking is flat, earning the student body's admiration as the school's Ice Queen. At school, she wears the standard Japanese uniform with a long ankle-length dress. Her father is an influential politician.
