Rules and Requirements
To level the field, the idols use their school dress cards during the first round and semifinals. However, during the finals, any coord may be used.
To determine if an idol moves on to the next round/wins the tournament or not, the voltage meter will be used. If the show ends up being to close to call, the live audience as well as the viewers watching from home are able to cast votes that break the ties.
- This is considered the tournament where Madeline Sycamore started getting her "Aikatsu Princess" title from.
