Nano volunteers to spend time with the trio of creepers so that Hakari can search for a male staff member to revive Rentarou. Hakari protests this course of action, but Nano believes that Rentarou cares more deeply for the girls he's known for longer. Hakari intervenes to refuse the creepers' company, provoking an attack that only gets stopped by Rentarou's face. After further arguing, Rentarou kisses Hakari and Nano to prove they're both his girlfriends, prompting the creepers to leave out of disgust.
Karane catches up to the group, explaining that she managed to revive Rentarou by telling him about Hakari and Nano's situation. Rentarou pleads for Nano not to be so reckless in the future, leading her to realize that Hakari was right about Rentarou caring about all of his girlfriends regardless of how long he's known them. Only now does anyone realize that Shizuka is missing, and Rentarou runs off in search of her.
Shizuka's phone runs out of battery, preventing her from signaling for help in the normal way. She sees Rentarou looking for her, and is forced to use her own voice to call out to her. Despite her soft voice in a crowded place, Rentarou manages to hear her and rescues her from the lazy river island.
Regrouping with the rest of the girls, Rentarou quickly deduces that Karane is wearing a towel not because she's chilly but because she's embarrassed. With this in mind, Rentarou strips off her towel while placating her insecurities about her appearance. With everything fully resolved, the pool date resumes in earnest.
Tropes
- A-Cup Angst: Karane covers up her body with a towel because she feels her figure in a swimsuit can't compare to the more buxom bodies of Hakari and Nano. Rentarou insists however that Karane has her own charm that he likes.
- Berserk Button: Rentarou is NOT happy to hear the creepers call Hakari and Nano shameless.
- Bitch Slap: Karane gives Rentarou several after he pulls off her towel.
- Blatant Lies: Karane insists that she's wearing a towel because she's chilly, even though (as Rentarou points out) a chilly person would not have ordered a melon soda float.
- Heroic Sacrifice: Nano attempts to perform a non-lethal one by hanging out with the creepers so that Hakari can get help for Rentarou.
- Instant Turn-Off: The creeps quickly give up on Hakari and Nano when they willingly kiss Rentarou, seeing them as shameless girls sharing the same guy.
- Oh, Crap!: Rentarou's reaction when he realises that Shizuka might have been drifting along the river all this time.
- Spit Take: Karane does one when Rentarou mentions that she was looking at Hakari and Nano's boobs a lot.
