異次元通訊2 is a unique adventure game developed by X.D. Network for Android users. The game is set in a contemporary city environment where the protagonist, Miko, is on the run. The only way for Miko to communicate with the player and share the details of the events is through the software. The game perfectly simulates a real-time messaging app, so players must keep an eye on their messages as Miko may require their help at any time.

Miko has her own personality and choices, and players must interact with her like a friend, observing her emotions, desires, and conversations. Miko also requires sleep and waiting time, so players must wait for her to come online to continue the conversation. The game's unique concept creates a realistic and emotional experience for players, making them feel invested in the game and connected to Miko.
