Cure Alumi inserts her Dress Up Key into her Princess Perfume to transform into her Elegant Mode. She raises her right arm up, and starting from there, she becomes bathed in light. As she says "Alumi", she lowers her arm, and the light travels to both of her hands. When she says "Spectrum", the light travels out of her hands to form a rainbow orb around the enemy, proceeding to explode and purifying the enemy. After the enemy is purified, Cure Alumi says "Gokigen yo".

- "Spectrum" refers to how light (Cure Alumi's power) can be separated into the rainbow colors, called the spectrum.
