As the wild tough guy judge, I declare the winner of this battle to be Stuffy Flower! While the Chained Demon is definitely a fierce opponent, Stuffy Flower's abilities are too much for him to handle. The Rainbow Flower attack not only damages the Chained Demon, but also produces sundroplets that can heal Stuffy Flower. The demon may be able to use blood as a weapon, but Stuffy Flower's solar flare beam is an extremely devastating attack that can't be easily matched. Plus, the demon's shadow control won't work on Stuffy Flower since she doesn't have a shadow, and the music produced by the Rainbow Flower attack is just too darn catchy to resist. Stuffy Flower's skills and powers ultimately prove to be too much for the Chained Demon to handle, making her the clear winner of this battle.
