A free program for Android, by Nuverse.

This is a rhythm or music game that introduces you to a group of five music-loving boys who accidentally enter a virtual ‘sekai’ or world – one that has been formed from their hearts – to help them find what their heart truly longs for – with the help of virtual singers.  

Meet the group of virtual singers: Hatsune Miku, Kagamine Len, Kagamine Rin, Megurine Luka, Meiko, and Kaito.

The game has 5 difficulty levels. It features an auto live function, so that you can automatically clear Live and gather your rewards. It also features a multi-live mode, where you can play with other players on the same stage. Fever or Super mode brings you additional rewards – especially when you complete Fever time.
