>>11293663AZKi doesn't dance at all so stamina doesn't factor into it.
Sora has good stamina and knows how to pace herself, she's definitely the best at long concerts.
Suisei is really fucking bad stamina wise. She's gotten better, but still nowhere near enough to do harder choreographies while singing for prolonged amounts of time.
Nene is fucking HORRIBLE at pacing herself. She has a lot of energy but runs out of gas just as quickly, every single one of her concerts so far she was dead tired and started getting incredibly sloppy after 3-4 songs.
