Absolute Rainbow Waltz (アブソリュートレインボーワルツ Abusoryūto Reinbō Warutsu) is the combined group attack between the Smile! Cures and Cygnet Drop. To use it, the Cures need to be in their Princess Forms and have their Princess Candles.
After the Cures use the Super Princess Decors to transform into their Princess Forms and Cygnet Drop installs her Super Odette Decor in the Altair Egg, the Cures and Cygnet Drop ride pegasi and a swan, respectively, made of light and combine their power to form a large white pegasus and white swan, which combine into a large beam of rainbow light, surrounded by white feathers, at the opponent.
