Class-D students (former)

An unmotivated student who is very poor at communicating with others. His grades are intentionally average and he is very conscious of how he spends his points. It is revealed that he has the academic aptitude and true intellect to make it to the top class if he wanted to, but for some reason, he aimed to get into Class-D. It was mentioned by Chabashira Sensei that he intentionally got 50 out of 100 points for every subject on the entrance exam. Despite not exhibiting any kind of fitness regimen, he is incredibly well-built and is seen as very skilled in martial arts, such that he held his own in a fight against the Student Council President, and beat Kakeru Ryūen and three other very skilled fighters in Class-C all at once. He is also shown to be extremely intelligent as he comes up with various grand schemes that fool and use almost everyone in the school. In a flashback, it is shown that he was part of an experiment performed by an unknown organization which is owned by his father, in an unknown facility called the "White Room" that forced children to participate in an immense battery of tests designed to raise and train children into teens with almost superhuman-like capabilities and he's shown to be the only one who meets all the criteria. He prefers to stay in the background and use other people to implement his plans whenever necessary. He is considered an unreliable narrator due to his ambiguous way of narrating with conditional statements and omitting vital information. Later on, he begins dating Kei Karuizawa, whom he appears to have romantic feelings for.

A selfish student with intellectual beauty, who secretly harbors a softer side by her so called brother. She joins Kiyotaka in class and is also careful about how she spends her points. Like Kiyotaka, she has trouble communicating with others but unlike him, she thinks friends are unnecessary. Kiyotaka is the only student in her class that she talks to and confides in him, as she seems to express interest in his insightful yet mysterious personality and has her doubts about him and his mysterious past, believing that he is hiding more than he actually lets on. She is seen as one of the most beautiful girls at school, and is constantly the target of many boys' affection, though she always turns them down. Her brother, Manabu, studies in the same school as her and is the former student council president, who distances himself from her due to the embarrassment that she is placed in Class-D. She also has knowledge of martial arts, as she was seen fighting Mio Ibuki, a Class-C student and held her own against her, despite being ill at the time. Her attitude seemingly improves for the better as she acknowledges her own hypocrisy by admitting that she is no different from her classmates when faced with a serious down-sided problem.

An attractive and popular girl in Class-D has a seemingly nice and cheerful personality and is also looking to befriend everybody at the school. However, behind her cheerful and caring façade, she has an alternate personality that is violent, cold-blooded, detestable and manipulative. She shows deep resentment towards Suzune, and yet she wants to get closer to her for an unknown reason. In the light novels, she was revealed to be from the same middle school as Suzune and assumed that she found out about her dark past. It is strongly implied that she may be developing feelings for Kiyotaka, though remains in denial and does not know how to properly understand them.

She was originally revealed to be a gravure idol, until her life was in danger of being chased by a stalker who worked in an electronics store and attempted to assault her, causing her unable to stand out anymore for the rest of her life. Fortunately, Kiyotaka and Honami came on time, saving her life and the stalker was arrested by the police, thanks to the security cameras located around the campus and the GPS tracking system on each students' school cellphones. She then feels deeply indebted to Kiyotaka, causing her to have an admiration/romantic interest for him for saving her while inspiring her with his encouraging words of wisdom to always do more than she would have done.

One of the top students in Class-D, who has issues with bullying. In the light novels, she initially perceives Kiyotaka as boring and nothing special, but slowly forms a very close trusting bond with him.

Later in the series, she is the only one who remembered and celebrated his birthday causing Kiyotaka to hesitate on deleting her messages, which he usually does and he also learned of her birthday and decided to do the same for her. She and Kiyotaka also call each other by their first names, also showing how close they are.

In later volumes, she gets confessed by Kiyotaka and they become a couple.

The top student in Class-D. His grades are worthy of being in a higher class, but he ended up getting stuck in Class-D for reasons yet to be explained.

In the light novels, he is shown to be quite close to Kiyotaka and it is revealed that both are actually close friends.
