Yokko appears as a minor figure in "Hana no Asuka-gumi! 2: Lonely Cats Battle Royale," depicted as a victim of bullying whose storyline addresses anorexia. Targeted harassment from other characters exacerbates her physical and emotional struggles. Throughout the narrative, she undergoes subtle but defined development. By the OVA's conclusion, Yokko resolves to recover, explicitly stating her intent to resume eating. This resolution occurs without direct intervention from the protagonist or main characters, rendering her arc a self-contained subplot within the battle royale framework. Her role remains confined to this specific installment, with no presence or development in other franchise media.
