The episode begins with an amusing and somewhat awkward scene where the characters prepare for a school performance. Nishimura, who is referred to as the "Grim Reaper" due to her quiet and withdrawn demeanor, plays the witch. Despite the derogatory remarks from her classmates, they recognize her endearing charm, which lies hidden behind the spooky role assigned to her.

Then the story shifts and focuses on Nishimura's school festival experience with Taiyou Takada. Yukiko, a friendly person from another school, gifts Nishimura a cute yukata and hints that she should wear it when attending the festival with Taiyou. This interaction clearly highlights the growing bond between Nishimura and Taiyou, as he sincerely compliments Nishimura's appearance and wholeheartedly offers to protect her.

During the festival, the duo explores the various stalls, foods, and attractions. Their interactions are marked by innocence and curiosity, paired with the underlying hint of a budding young romance.

The episode does not shy away from introducing a minor conflict as rumors about a date between Taiyou and Nishimura circulate. Despite the uncomfortable situation, Taiyou responds positively and expresses his joy at spending time with Nishimura.
