Joyful Everlasting Summer! Cure Summer!

The transformation starts with Manatsu's Tropical Pact appearing. She then holds the pact while removing her Heart Kuru Ring, inserting it into the lock and turning it. The pact opens up, revealing her reflection. Then Manatsu takes the brush and shouts "Let's make up! Bling!" before touching the center of the pact with it, causing it to glow. She then shouts "Cheeks!" as she presses it against her cheeks, giving them a rosy glow. She taps the middle of the pact again and shouts "Eyes!", giving her pink eyeshadow and adding pink heart-shaped flecks to her eyes. She taps it again and shouts "Hair!" as her hair ribbon turns into a giant flower and her hair grows and turns blonde with a magenta ombre. She once again taps it and shouts "Lips!", applying pink lipstick. She taps the middle one more time and shouts "Dress!" as she draws a heart with the brush, which splits into eight hearts. Each of the hearts strike her body, making parts of her outfit appear. First are her shoes, followed by her gloves, then her skirt, top, choker, and earrings. A pouch for her Tropical Pact appears on the left, dropping in. With the transformation complete, Summer runs and leaps into the air doing several spins before starting her introduction. She then winks before announcing her name and striking her final pose.
