The MonoMono Machine (モノモノマシーン) is an in-game gashapon machine which dispenses Presents in exchange for Monocoins. Presents can be given by protagonists to other students in order to increase their bond during Free Time Events, and each student prefers different items.
After inserting a Monocoin into the MonoMono Machine, the player will receive a random Present item, which can be found in the e-Handbook menu. The player will start with a 0.00% Repeat Chance. The Repeat Chance reflects the likelihood that the machine will dispense an item which the player has already received, which will slowly increase each time a new Present is received. The more presents the player has collected, the more likely they are to receive a repeat present. The Repeat Chance can be lowered by adding additional Monocoins to the machine, up to 100, but the player will still only receive one item, so it should only be used to obtain the last few items the player is missing.
At any time when inserting a Monocoin, there is a chance that a "LUCKY!" event will be triggered, and the MonoMono Machine will dispense an extra item. Sometimes this "LUCKY!" event will repeat in a chain and the player will receive multiple items for a single coin.
