第 12 集: First Astronomical Velocity 計畫在預算受限與設備問題下，仍舉辦跨年演唱會。

First Astronomical Velocity decide to hold a concert for New Year's Eve, but Suzu ends up overspending her budget, leaving them with no money for speakers. Wanting to go ahead with the concert, each of the members asks for favors from their friends and neighbors to help put the concert together, even helping to stream it on the internet. Although the concert gets off to a good start, the strings on Sonico's guitar break midway through the performance. However, her grandmother, Leila, manages to save the day with her own guitar, buying time for Sonico to replace the strings. Looking back over the past year, Sonico and all her friends and supporters see the new year in together. (Source: Wikipedia)
