Konkei Yufuin (湯布院 献景, Yufuin Konkei) is a senior classman of Hakoniwa Academy and one of the delinquents who originally made up both the Kendo Club and the 2% of the votes that Medaka Kurokami did not receive.
Yufuin ignores the great majority of school rules, instead hanging out in the kendo hall with his friends. Like the rest of his gang, he smokes. After Medaka's intervention however, he seems to have reformed somewhat, and the passion for kendo he once had has been rekindled.
Yufuin has black hair. He forgoes the uniform of a student of Hakoniwa Academy, instead wearing a brown shirt and dark pants, as well as a white jacket with the collar up. He wears red-tinted glasses and has a short beard. He is also seen in his kendo uniform.
Suggestion Box ArcEdit
Yufuin is hanging out at the Kendo Hall when Medaka and Zenkichi Hitoyoshi arrive. At Mahibi Moji's order, he and the others surround the pair. He is amazed when Medaka manages to confiscate the cigarettes of everyone present before they can react. He is horrified when Medaka declares she will reform all of them. The next day, the group returns to the kendo hall in uniform, much to Zenkichi's surprise. After Medaka leaves to attend the Student Council Recruitment meeting, the Kendo Club is attacked by Habataki Hyūga, who defeats them all. To Hyūga's shock, Moji gets back up, proclaiming that even he was once passionate about kendo. Inspired, the other members rise back up as well. An enraged Hyūga attacks them, only to be stopped by Zenkichi. After being "converted" by Medaka, Hyūga takes over the Kendo Club and shares the hall with the other members, though he and Moji sometimes butt heads.
