Shortly before episode 14, after receiving souvenirs from Tsumugi's trip to Finland following the summer festival, the girls decide to plan for an overseas trip after graduation. They practice various things for overseas travel, only to realize that, besides Tsumugi, none of them has a valid passport. While lining up to hand in their passport applications, Ritsu realizes she forgot her identity card so she sends her little brother Satoshi to fetch it. Mio needs to take a suitable photograph to complete her application, but keeps getting bothered by the others while attempting to take it. With everyone having their own ideas of where they would like to go, Yui suggests that they go on a second trip after Azusa graduates.
