Normal quests are comprised of both popular songs based off of Crypton's vocal software and songs from popular producers. Players will need to collect the four magical notes in each stage along with clearing the last stage to move onto the next stage. As you collect each magical note, the tune of the original song will slowly come back. Each stage in each area also contains treasure chests that contain one MikuCoin.
As of the August 25th, 2016 update, Area 1 ~ Area 6 all have been shortened down to four stages.
Note: Upon clearing the last stage of each normal quest area, the next area will begin downloading. Please make sure you're in an area with a strong signal to avoid getting Error 0.
