FlowerPetals is the first group formed and debuted under Twinkle Project. Created by Rora in 2015, the group covers different Hello! Project groups and units.
​
Although the group is small, they spend time deciding on which songs to sing next together and everyone has a say in final profiles as well as mixes. All of the art, videos, and mixes are done in group by staff Aya (art and videos) and Maru (audio mixes) - formerly done by Kanko. Their original videos have become one reason the group is known and well enjoyed.
