Ep. 19: Kurita and Yamaoka help Inspector Nakamatsu improve his love interest's ice cream business in Roppongi

19

Kurita and her friends visit Yamaoka in Roppongi, where they encounter a crowded ice cream parlor. During the wait, they witness Police Inspector Nakamatsu being removed for causing a disturbance. Upon questioning, Nakamatsu reveals his affection for Utako Mizumori, an ice cream saleswoman whose business is struggling. The group tastes her product and notes that despite high-quality ingredients, the texture is dense and heavy. Yamaoka proposes a solution by comparing the aeration levels of Roppongi’s popular ice cream against Mizumori’s using a samurai sword. She demonstrates that the superior product has more air, creating a melt-in-the-mouth sensation. Mizumori adjusts her manufacturing technique based on this insight, leading to a significant increase in her shop’s success.
