Yuina Rokkatei, a 16-year-old with vivid multicolored hair and sharp petrol-hued eyes, stands at 1.59 meters. She performs as part of the Hokkaido-based manzai comedy trio Shinryakusha, competing alongside Mone Ishiya and Chihori Hokuto in the Teppen Grand Prix. This high-stakes contest pits regional trios against one another, housing them in a shared dormitory as they craft and rehearse routines. A defining moment arises when Chihori Hokuto manipulates a time loop during practice, granting Yuina endless repetitions to perfect her comedic timing—a testament to her relentless drive. This event crystallizes the trio’s delicate balance of camaraderie and rivalry, as each member pushes boundaries to claim victory in the competition.
