Hakugen Rikuson, a female student of Nanyo Academy and former attendee of Gogun Academy, sports black hair fastened at the back of her head, circular glasses framing her orange eyes. She dons a red-and-white track jacket layered over a matching shirt, paired with brown spandex. Standing at 1.45 meters, her figure measures 68/52/76. Known for her kind demeanor, Hakugen shows particular care toward peers like Ukitsu, often expressing visible concern during Hakufu Sonsaku’s rigorous dragon-control training at a mountain waterfall. When Ukitsu succumbs to exhaustion from channeling energy to stabilize Hakufu’s dragon, Hakugen mourns her loss and honors her final wishes by transferring to Nanyo Academy under Master Choukou’s directive. Her role primarily involves witnessing pivotal moments, including Hakufu’s training under Choukou and Shiryuu Chou-un’s intervention to halt the rampaging dragon—a clash that leads to Ukitsu’s fatal collapse. While Hakugen’s relocation concludes her documented involvement, her activities beyond this transition remain unrecorded.
