The story of MiSide takes place in an apartment setting. It begins with the player interacting with Mita, a character from a mobile game that the main character (MC) downloads from his smartphone.[5] Players solve puzzles, explore the apartment, play games and discover hidden secrets in a tense and evolving environment. Initially, the app presents a 2D, Chibi style, bird's-eye-view environment. After progressing to the 37th in-game day, Mita unexpectedly asks to meet the player in person. When the MC looks up from his phone, he is transported into a 3D version of the game world, now seated on a couch in an apartment. In this new environment, the player must adapt, complete tasks and play games with Mita.[6]
