As Ayuko goes to the festival with Kouhei, she spots Akira with Aika and decides to follow them. As Akira tries to hold off the advances of Aika, Mikoto appears in a box robot, suggesting they do a blind taste test of each of their drool to see which Akira prefers. Akira instantly gets a nosebleed from Mikoto's drool, due to the fact she was naked inside her costume. Aika gets naked and attempts to give Akira her drool, but she stops when she starts crying, making it clear that her advances on Akira was simply an attempt to get over losing her boyfriend, who had feelings for someone else even when he was dating her. Mikoto tries some of Aika's drool, sensing she has long had unrequited love but assuring her she'll one day find the right someone. Just then, Akira's blindfold gets shaken off and he sees the girls naked, prompting slaps from the both of them. As Akira and Mikoto leave together, she tells him that her eventual kiss with him will be her first, prompting a smile when she tries his drool.
