Kouhei Katsuragi

Age: 16
Birthday: August 29
Height: 180 cm (5'11")

Kouhei is an intelligent student who worked very hard to reach Class 1-A that he became one of its representatives.

He is a serious man who adheres to the rules of manners and good conduct as he reprimanded another student of the class for making fun of Sudo Ken and his classmates. He was calm in telling Ken 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.
Due to a childhood illness, Kouhei lost all of his hair. He has a sister and they are originally orphans.
