SideMini

SideMini is a section of the game where the player can leave Souvenirs for chibi versions of the idols, after which the idols will give back a small Item in return. SideMini also refers to the chibi version of the idol themselves.

Office
      At the office, the player can leave a Souvenir. After 30 minutes, a random idol will appear, and leave a small Items (such as event stamina jelly, event AP bars, money, or scout points). A Whistle can be used to call upon idols quickly, while a normal timer for a SideMini to come after a souvenir being placed is 30 minutes. Various Souvenirs can be left at the office. Some souvenirs can only be used in an event period and will disappear once event ends/changed (red background), while the rest are permanent (blue background).
