Kusuri explains that Nano had followed her into the lab, having realized that Kusuri was helping Rentarou, and Rentarou can't make a break for the lab without giving away Kusuri's position. Kusuri laments how her obsession with drugs led to the rest of the chemistry club abandoning her in the past and resolves to stop making drugs.
Suddenly, Kusuri remembers that she has a dose of the neutralization drug on her person. Rentarou thinks she's planning to use the dose on Nano so they can return to the lab unhindered, but Kusuri drinks it herself to revert to her adult body, hoping that Nano wouldn't recognize her. This mixup causes the drug to be spilled before Kusuri can finish it, so the effect won't last as long.
Kusuri emerges from the locker and initially manages to escape Nano's attention. But she promptly gives herself away when she refers to herself in third person and gets tied up with the rope she planned to use on Nano. At this, Rentarou bursts out of the locker and makes a mad dash for the lab, getting caught by Nano in a storage closet.
Just then, Kusuri arrives and administers a neutralizer to Nano, having escaped her bonds when her neutralizer wore off. With Nano saved, Rentarou and Kusuri head off to make batches for the other girls.
After the girls awake from their bender, and Hakari and Karane bashfully claim not to remember anything from the escapade, Kusuri apologizes for the whole mishap. Rentarou explains that while she did start the whole thing, she was still able to fix her mistake. As such, Rentarou promises to continue to love Kusuri even if she continues making drugs, and resolves to help her clean up any messes made in her wake.
Kusuri thanks Rentarou and reaffirms her love for him and her drugs.
