Ep. 6: Ako and Riko hide their adult shopping trip in Akihabara from Keita
Ako and Riko plan to buy erotic games in Akihabara because they cannot access internet pornography on their father's raffle prize PC. Keita accompanies them, so the girls devise a plan to conceal their true intentions. Ako distracts Keita by visiting a cosplay shop while Riko searches for adult content. During a costume change, Ako encounters her teacher, Yuuzuki Kiryuu, a closet otaku dressed as Mahoro from Mahoromatic Maiden. Riko later meets Kiryuu while seeking a special edition game. Kiryuu, reminded of the girls' crush on Keita, takes him to a cosplay-themed love hotel. Ako and Riko find them, where they meet Keita's kouhai and Kiryuu's younger sister, Mikazuki. Mikazuki covers for Kiryuu by claiming she bought the game, and in exchange, Kiryuu agrees to cosplay as Mai Shiranui for her that night.
