SEGA did a special price cut on the smartphone, anime based music game the Pop in Q Dance for Quintet! This is the official game of the Pop in Q anime movie which released in 2016 December in Japan and this sale celebrates the release of the BD / DVD version of it.
So from today, until June 18, 2017 you can buy the game for 960 Yen (with tax) instead of 1200 Yen (with tax) which is 20% OFF from the original price. This game is like a Hatsune Miku o game, where you have to pay attention of the signs on the screen and you have to top on the right time. You can play with tracks from the animation with original video clips in the background.
