Boyfriend from FNF never runs out of opponents. This time he went to Japan and met Hatsune Miku who is a rising music star. The two decided to measure their strengths and clash on stage. This is going to be a fascinating experience! Prepare to rap to a bunch of new songs that will definitely sound no worse than those you have in your daily playlist. You need to outscore Hatsune by hitting the buttons with arrows just in time with the beat.
