SoniPro is a management simulation and rhythm game featuring Nitroplus' mascot character Super Sonico. It plays much like a combination of the earlier SoniComi and Namco's The Idolmaster. The player takes the role of a young producer at a talent agency who has been tasked with developing Sonico's talents, image, and career. While she may be a beautiful young girl with a great singing voice and skill with a guitar, she is still inexperienced, rather naive, and lacking in confidence, and as such needs proper guidance to become a real star.
The game is broken up into three distinct sections. The bulk of the game is spent in conversation mode, where the player speaks with Sonico and the other characters, as well as plans her schedule and events. Quite often there are dialogue choices which will influence Sonico's progress and character, which in turn leads to different types of job requests. There are also two types of events; Live Events and Gravure Events. Live Events are a live performance of a song, which plays out like a simple rhythm game, while Gravure Events involve taking photos of Sonico in different outfits, and giving her instructions on how to pose. Performance in each of these sections also determines Sonico's popularity and influences her career.
There are also Free Live and Free Gravure modes available, where the player can simply enjoy the unlocked content for fun without without worrying about specific requests or career progress.
