The popular female singer Terakada Otsu gives a concert where Shinpachi and his fan club are as well. When they get out at the end of the concert, Shinpachi notices that there are only four members within his fan club left and all the other members quit and joined the Tsusengumi fan club instead, whose leader is no other than Toshirou Hijikata in his otaku character. As Shinpachi gets to the Yorozuya house and tells Gintoki about it, Toshi appears and after Shinpachi saw a TV announcement of Otsuu's where she tells everyone that she will make a contest to decide which group will be her official fan club, the battle between the Tsusengumi and The Terakada Tsu Fan Club begins.
