This event lasts until November 7th, 20:59 JST (countdown timer here).

In this event, you are to select a difficulty, and the game will randomly generate a medley consisting of three songs. Songs are selected based on which Groove type it is. All-Type songs will also be selected in any of the Groove types. Only the idols with the same type as the chosen Groove get the 30% same-type Appeal bonus even on All-Type songs.

Your unit's Dance appeal is increased by 150%, thus making it easier to achieve higher score if your unit is Dance-based. This is vital to making into the high-score ranking.

You can change your Groove type and songs if you don't like the songs the game selected. It costs 30,000 money to change it. Press the GROOVEを変更 button to do so. This will select a Groove of a different type from your original selection. You can change Groove again for the second and final time for 50,000 money.

All right lads, I like the featured idols in this event, as well as the featured song, too. I think I will actually try to get enough points for Yuka.

Good luck ya'll!! I love autumn and i love this song and its album, too!
