Not long ago we shared a series of three story-driven videos that were released to promote Miitomo. Entirely in Japanese, it's nevertheless relatively easy to pick up the themes and general idea of the story - you should check them out.
Part of the plot in those videos revolved around the main characters' mutual love for music, culminating in their different tastes coming together in a live show. The latest in the series, simply titled 'Miitomo Live', is basically a music video for the mini-series. It's a High School rap about Miitomo, and is quite a charming watch.
Miitomo may not have taken off to quite the degree Nintendo and DeNA will have hoped, but we've enjoyed these story-based videos that highlight how the app can help bring users together.
In any case, this song may be the only decent Miitomo rap we ever get.
