Kōhei Katsuragi

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

Appearance
Kōhei is a well built young man above average height. He has bald head and a 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 class representative.

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 manner did intimidate him into not 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 just annoyed by their antics.

He expresses slight anger when some of his failures, such being rejected on being part of the Student Council was mentioned as he was annoyed by Kakeru Ryūen bring up one.

Trivia

 * According to Kakeru Ryūen, Kōhei was denied in trying to be apart of the Student Council, for unknown reasons.
 * In Episode 9, he is shown to be an intelligent man, as he was able to find a spot on the deserted island, while he was on the deck of the school's cruise ship, which did one lap around the island, by looking for the shortest routes.
