Kōhei Katsuragi

Kōhei Katsuragi is a student and the class representative of class 1-A along with Arisu Sakayanagi.

Appearance
Kōhei is a well built young man of above average height. He has a bald head and large body frame compared to other students, which contributes to his intimidating appearance.

Personality
Kōhei is an intelligent student who worked very hard to reach Class 1-A and became one of its representatives.

He is a serious man who adheres to the rules of manners and peace as he reprimanded another student of Class A for making fun of Ken Sudō and his classmates. He was calm in telling Sudō not to get easily provoked by his classmates' actions but his demeanor intimidated him into stopping from arguing any further. From this display, it shows he is one of the few upper students who have no problems in associating with those of the lower classes or that he was simply annoyed by their antics.

He expresses slight anger when some of his failures were mentioned, such as when he expressed annoyance after Kakeru Ryūen brought up him being rejected from joining the Student Council.

Plot
Kohei was first seen besides Arisu Sakayanagi listening to Manabu Horikita as he officially welcomes each student to the school.

Kohei was next seen with Arisu along with several other students being congratulated and was asked the extent of what they know about the S-system.

He makes another appearance again with Arisu looking at the scores of each class, remarking the advancement of C Class before following with a statement that Kakeru Ryuen is a dangerous man, to which Arisu simply responded by asking how boring it is.
