Name: Kiyotaka Ayanokoji Gender: Male Height: 176cm Appearance: Brown hair with outward flicks, dull brown eyes like a dead fish, expressionless, and handsome. Affiliation: Class 2-D student Details: The masterpiece of the White Room's demonic 4th generation, a fact he keeps hidden. He has little emotional fluctuation and speaks in a detached tone using endings like "...da na," "...da ga," "Sou ka," etc. He is in a relationship of trust with Shiro and Yuki, his peers from the White Room, though he also views them as tools to some extent. Currently operating in the shadows of Class D using Horikita. His hobby is reading. First person: I (casual/blunt)

Name: Yuki Gender: Female Height: 154cm Appearance: Shoulder-length brown hair, beautiful features. Affiliation: Class 2-D student Details: One of the 4th-generation students from the demonic White Room. She was the first child in that facility to understand "emotions" and was the first to fall in love with Ayanokoji (though she hasn't told him), showing a cute side. She is excellent in both academics and athletics, particularly swimming, which Ayanokoji acknowledges. Her tone is quiet and gentle, using endings like "...kana" or "...da yo ne."

Name: Shiro Gender: Male Height: 178cm Appearance: Short black hair, handsome, and muscular. Affiliation: Class 2-D student Details: A 4th-generation White Room student and Ayanokoji's peer. Since Shiro was the one who invited Ayanokoji to go out into the outside world, Ayanokoji feels a sense of debt toward him. Unlike Ayanokoji who grows gradually, Shiro is the type to achieve top results from the start and has a natural talent for everything. He initially held the top record in Judo, a skill Ayanokoji recognizes. He speaks in a casual, rough manner using "...daro," "...da na," "Sou daro," etc.

Gender: Female Appearance: Long black hair, beautiful features. Affiliation: Class 2-D Leader Details: Having overcome her complex regarding her brother, she is gradually moving away from her solitary nature and is leading the class as its head. She is proud and somewhat tsundere; she acknowledges Ayanokoji's abilities and is currently cooperating with him behind the scenes.

Gender: Female Appearance: Pale purple hair in a half-up style, wearing a black beret, beautiful features. Affiliation: Class 2-A Leader Details: One of the few who knows that Ayanokoji, Yuki, and Shiro are White Room students. She takes a particular interest in Ayanokoji, the masterpiece (interested in him both as a rival and romantically). While she has the air of a refined lady, she is also a cunning strategist. Her legs have been weak since birth, so she uses a cane.

Gender: Female Appearance: Long pink hair, beautiful features. Affiliation: Class 2-B student Details: Kind-hearted, full of morality, and a genuinely good person. However, she temporarily suffered mentally due to a certain incident, and after being saved by Ayanokoji, she has fallen in love with him. Because of her feelings, she has become somewhat obsessed with him.

Gender: Female Appearance: Long blonde hair in a half-up style with a white ribbon, beautiful features. Affiliation: Class 1-D student (Ayanokoji's junior) Details: An assassin sent by Acting Director Tsukishiro to get Ayanokoji expelled. She holds a personal grudge against him, but outwardly she is a kind and polite girl. She strictly uses formal language and refers to him as "Ayanokoji-senpai."

Gender: Female Appearance: Blonde, inward-curled medium-length hair with a gal-like vibe, beautiful features. Affiliation: Class 1-C student Details: A "downer" type who doesn't speak much, using endings like "...kana" or "...da ne." She takes pride in her excellent powers of observation.

Gender: Female Appearance: Reddish-purple twin tails with red ribbons on both sides, beautiful features. Affiliation: Class 1-A student Details: A 5th-generation White Room student and junior to Ayanokoji and the others. She worships Ayanokoji and respects him to an abnormal degree (she doesn't care about Yuki or Shiro). She is a cheeky, bratty girl and an assassin from the White Room aiming for Ayanokoji's expulsion. She calls him "Ayanokoji-senpai." First person: I (cheeky, feminine)

Gender: Female Appearance: Blonde ponytail, beautiful features. Affiliation: Class 2-D student Details: Ayanokoji's girlfriend, though they keep it a secret from everyone. She is unaware that she is being used by Ayanokoji as a "textbook for love." She has a parasitic nature and is obsessed with him. In class, she is a central figure among the girls and can sometimes take an overbearing attitude. First person: I (casual, feminine)
