Madoka Hongō is a fourth-year student at Koufuuin University and plays fullback for its rugby team. He possesses medium-length light-green hair and orange eyes, frequently seen wearing the team's yellow uniform during matches or fashionable clothing off the field.

His personality blends charm and persuasiveness with a provocative edge, naturally drawing others to follow his lead. He inspires improvement through encouragement and strategic guidance, recognized for cunning coaching methods that earned him the nickname "Creator of the Backs" for developing exceptional backline players. This influence manifests in interactions like challenging Ikuto Yufu on career choices or subtly aggravating Seiichirou Shingyouji.

He attended Maisagi High School with his younger brother, Kazutaka Hongō, where both gained rugby renown. Their high school teammate, Ibuki Ueoka, dubbed Madoka "The God of Backs" and Kazutaka "The Forward God of Destruction," titles persisting into university. During Kazutaka's childhood, Madoka redirected his brother's tendency for school fights by enrolling him in rugby, mirroring paths taken by peers like Natsusa Yuzuki and Seiichirou.

His coaching extends to players including Yasunari Tsuru, Ibuki Ueoka, Seiichirou Shingyouji (indirectly), and Natsusa Yuzuki, reinforcing his role as a strategic influencer beyond his on-field position. His name reflects his character: "Madoka" (円) means "circle, yen, round," while "Hongō" (本郷) signifies "base, root, origin" and "township, home town."
