As the Neighbor's Club rest by a bench after riding the 'Black Dragon' roller coaster, Kodaka, Kobato and Sena went to watch the costume show for 'Kurogane no Necromancer' after hearing its announcement and left their fellow club-mates and decided to meet up afterwards. At the show, Sena acted as if she was a 'Kurogane no Necromancer' fan which angered Kobato, who is a hardcore fan of the anime series, after Sena got all wrong answers as Kobato gave her trivial questions about the anime. By that time, the costume show started and Astaroth, the antagonist of the anime series, appeared and asked for hostages in the audience which will be given prizes afterwards and Sena happily volunteered to be one and planned to achieve the price as an offering to Kobato, which the latter denied on accepting. The MC and Astaroth then mistook Sena as the mother of Kobato and Sena claimed that Kodaka would then be the father, much to his annoyance as Sena complained on Kodaka's denial on them being a couple. Afterwards, Kobato was called up to the stage into becoming one of the hostages of Astaroth.
After their exchange, Kobato received an autograph of the show's director from Astaroth which Kobato happily treasured. Kodaka then reminded Kobato that Sena was the reason how she got the autograph and Kobato timidly thanked Sena before running away. Kodaka then thanked Sena as the latter then got flustered on how the MC and Astaroth mistook her and Kodaka as a married couple earlier. When Kodaka iterated to Sena that the MC and Astaroth didn't mistook them as married from the start, Sena murmured to herself that she and Kodaka should start dating first before getting married.
