Rentarou introduces Kusuri to the rest of the harem, with Kusuri gifting the other girls with drugs based on what she heard about them from Rentarou. Karane beats up Rentarou until Kusuri explains that the selection she came up with for her was based on things Rentarou likes about Karane. Hakari gets a "become even sexier" drug, which causes her to literally sweat all of her clothes off, prompting Rentarou to provide her his jersey to cover up. Shizuka gets a drug that gives her rabbit ears, which makes her feel euphoric when Rentarou touches them. Nano gets a hair manipulation drug, which comes with a slight risk of baldness, prompting Nano to dispose of the remaining doses when Rentarou says he loves her hair.
Kusuri provides the group with cookies and tea, but suddenly needs to go to the bathroom. She tells everyone that one of the two thermoses is for Rentarou before leaving. Everyone assumes the big one is for the girls and pour the contents for the girls. When Kusuri returns, she realizes that the girls are drinking the tea from the thermos that would hold up to Rentarou's tough grip and tries to warn the others, but it's too late. Kusuri explains that she intended to spike Rentarou with a drug that would make him want to do nothing but kiss her, and that its effect on women is comparable to being transformed into zombies.
They now have one hour to administer the neutralization drug to all four of them, or they'll be stuck in this state forever.
Tropes:
- Catchphrase Interruptus: Kusuri doesn’t wait for Rentarou to finish his catchphrase before introducing herself to the other girls.
- "Could Have Avoided This!" Plot: Rentarou tells Kusuri that she didn’t need to drug him to get him to kiss her.
- Deadpan Snarker: Karane's response to Rentarou telling the girls that Kusuri hasn't done meth yet is a sarcastic "Gee, what a convincing way to put our minds at ease."
- Eye Pop:
- Karane does one when she learns that Kusuri is actually eighteen.
- Kusuri does one when she realises that the girls are drinking the tea she put in the thermos meant for Rentarou.
- Rentarou does one when he sees what the effects of the drug actually are.
- Oh, Crap!: Kusuri's reaction when she realises what the girls are drinking.
- Poor Communication Kills: The entire plot of both this chapter and the next two could have been avoided if Kusuri had been more specific about which flask was meant for Rentarou.
