Mahibi Moji (門司 真罅, Moji Mahibi) is a senior classman of Hakoniwa Academy and the leader of the delinquents who originally made up both the Kendo Club and the 2% of the votes that Medaka Kurokami did not receive.
Moji is aggressive and violent, an attitude befitting a delinquent leader. He 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.
Moji forgoes the uniform of a student of Hakoniwa Academy, instead wearing pants, a jacket, a black shirt, a necklace, and earrings. He has spiky brown hair (blue in the anime) and an x-shaped scar on his left cheek. He is also seen in his kendo uniform. Ten years later, Moji wears a sports jersey.
Suggestion Box ArcEdit
Medaka's first request was to clear out the delinquents in the kendo hall. Confronted by her and Zenkichi Hitoyoshi, Moji arrogantly pointed his sword at them. Medaka easily disarmed him, and later managed to take all of his gang's cigarettes when they tried to surround her and Zenkichi. She then preaches to the Kendo Club, believing them all to have suffered some great tragedy to have become the delinquents they were, before promising that she will drill the way of the sword into them, so that they would never be lead astray again. The next day, the group returned to the kendo hall in uniform, much to Zenkichi's surprise. Moji admitted that while they may be a bunch of low-lifes, they weren't cowards, and that they would not give up the kendo hall. After Medaka left to attend the Student Council Recruitment meeting, the Kendo Club was attacked by Habataki Hyūga, who defeated them all. He revealed himself as a kendo expert, and, not wanting to share the hall with anyone, requested that Medaka clear out the hall so that he could have the then defunct Kendo Club all to himself. To Hyūga's shock, Moji gets back up, proclaiming that even he was once passionate about kendo as well. Inspired, the other members rise back up as well. An enraged Hyūga attacks them, only to be stopped by Zenkichi, who defeats him with one punch. After being "converted" by Medaka, Hyūga takes takes over the Kendo Club and shares the hall with the other members, though he and Moji sometimes butt heads.
Club Battle Swim Meet ArcEdit
At the club battle swim meet, Moji is seen as one of the participants representing the Kendo Club, along with Hyūga. As usual, the two do not seem to be getting along. He and Hyūga take part in the second event, the three legged race.

At the end of the third event, the Kendo Club is in sixth place overall.

Despite her warnings, Moji and his friends brush Onigase off. After Myouri Unzen blows up the Student Council office, Hyūga hears the commotion and questions Moji about it. When they both realize where the noise came from, they both brush it off as Medaka simply being up to her usual antics.
Student Council Battle ArcEdit
Walking past the Student Council's office, Hyūga and Moji hear a horrified scream. Moji wonders at the noise, while Hyūga suggests that perhaps the Nonexistent Youth Bill has been confirmed. At the end of the semester, Moji is present for Medaka's speech. He is surprised by Misogi Kumagawa's sudden entrance, and declaration that he is Medaka's ex. On August fifteenth, Moji is among the students who come to the Vice-President's Battle to cheer for Kuudou Hinokage.
