In UMCC you play as the cheerful and buxom girl, Umiya Maiko. Unknowing to her, she was chosen to shape the future of many people’s lives by being given a special hairpin that gives her powers. In the game, while being completely obvious to the serious events going on elsewhere, Maiko lives her normal school life by working to become better than her rival Luma in every way. Her goal is to beat Luma in all kind of club actives within the school on campus. Luma has a posse of friends that pick on Maiko and bully her at the start of the game. The player can level up Maiko in all kind of stats such as swimming, running, powers and fighting ability in order to beat Luma in the various activities. Players can also have Maiko learn new abilities and actions by having her read and study books.
