Luri Nonomiya, known as Nonomi, maintains an innocent outward appearance that sharply contrasts her enthusiastic engagement in sexual pursuits. She lives in the same dormitory as Takurō Hayami among other female students. Nonomi shares a particularly close bond with Yuuki Miyagishi, regularly partnering with her to orchestrate sexual encounters involving Takurō. Their coordinated efforts target moments when Takurō exhibits sexual thoughts or reactions toward others, deliberately initiating intimate situations. Throughout the series, she consistently participates in group sexual activities with Takurō and fellow dormitory residents.
