The success of the open day helps bring the faculty to reconsider the closing of the school, as well as earning the group an expansion to their club-room. After the group manages to reach 50th in the rankings, they visit Akihabara where they find they are already being featured on merchandise. Upon discovering a photograph of Kotori in a maid's outfit among the goods, they learn that Kotori has been secretly working part-time at a maid café after school to build her confidence. Eri decides Akihabara would be the perfect place to hold a live performance, assigning Kotori to write a song about Akiba culture. However, Kotori struggles with coming up with lyrics, which soon has an impact on her studies. In order to help her out, Honoka and Umi join her at the maid café. Recalling the feelings she gets whenever she works in Akiba, Kotori is able to come up with some lyrics which help make the performance a success. As Honoka assures Kotori that they'll be together forever, an air mail letter arrives in Kotori's postbox the next morning.
