Following the intense events of the previous evening, Janu reflects on the blurred lines of his relationships and his potential capacity for manipulation. As the Culture Festival continues, he encounters Omina, who has arrived at the school wearing her sister Oki’s uniform as a disguise. Janu agrees to escort her through the festival, advising her to keep a distance so as not to provoke Oki’s ire.
As they explore the festival, Omina displays a childlike curiosity and naivety, struggling with the concept of food poisoning after overindulging in fried snacks. Their interactions are interrupted by Sora and Dayai, who briefly interact with the pair. Throughout their outing, Omina admits that her desire to experience the festival was motivated by her wish to share the experience with Janu, noting that he is her only friend in this world. After helping Omina select a souvenir mask and acknowledging their complicated dynamic, Janu prepares to continue his day as Omina resolves to return to her isolated life, albeit emboldened by her brief taste of freedom.
