Lucky Besties! Engage!

Lucky Besties Engage! is the transformation of the Lucky Besties in Lucky Besties. To transform, they must have their Lucky Bracelets and their Lucky Gems.

Trixie to Lucky Tricks
Trixie inserts her Lucky Gem and says the incantation. A cumulonimbus cloud made of what looks to be cotton candy explodes into lightning, and her gauntlets appear. Trixie winks as her hair glows blue, thickens, and curls. She taps her heels together to make her boots appear, and starts to jump on cumulus clouds. Tricks’ dress appears, followed by her hair bow. Tricks makes a lightning shape on her chest, making her dress bow appear. Tricks then lands and says her introductory phrase.

Arle to Lucky Harmony
Arle inserts the gem into her Lucky Bracelet and taps it 3 times, saying the transformation phrase. Light envelopes her body, forming a glowing yellow dress as she starts to sing. She winks and dances, and flicks a strand of her hair as a string of music notes changes it's color. A string of music notes spins around her hair, changing it's style. Arle continues to sing, as stars fly down and Arle floats and lands on a stage-like platform, complete with an audience waving penlights. The platform seperates into three pieces, and stars form Arle's top. Arle jumps to the next platform, forming her gloves. Another platform, and her shoes form. The penlights explode into musical notes and stars, forming Arle's skirt, and the outfit comes together as Arle dances and sings on a stage-like platform, with yellow penlights in the audience. The platform and penlights explode, as Arle winks and flies down, landing on a sparkly stage similar to the budoukan, complete with a full audience with glittering yellow penlights, as Arle finishes her song and introduces herself. The stage platform turns into a sparkly yellow platform, as Arle strikes a pose, with music notes surrounding her, and completes her introduction.

Akari to Lucky Rainbow
Akari inserts the gem into her Lucky Bracelet and says the incantation. Rainbow sparkles fly down as Akari does a backflip. She lands on a red sparkle-shaped platform as her legs and arms start glowing, thus forming her boots and arm warmers. The platform explodes and she falls, but lands on a red diamond-shaped platform as her outfit forms. The platform explodes again and the sparkles fly down on her hair, thus changing her pigtails and ahoge, as well as adding red ombre to her hair. She winks and flies down, landing on a red ground covered in sparkles. She then says her introduction and spins around, forms two peace signs with her hands in front of her face, and says "Lucky Rainbow!"

Akira to Lucky Starlight
Akira inserts their Lucky Gem into their bracelet and says the transformation phrase. The bracelet starts glowing light turquoise and disappears from Akira's wrist, and reappears on their head, now in the form of a headset. Akira starts to sing and lands on a stage. The sounds of people cheering for Akira can be heard. Akira starts to sing and a bunch of stars rainbow down, changing Akira's hairstyle and hair color. Akira dances around and their arms and legs start to glow, forming their arm warmers and shoes. Akira spins around and their outfit forms. Akira stops spinning and winks, and makeup appears on their face, and then wings appear on their back, and they fly down and land. Akira strikes a pose and they says their finishing phrase.

Trivia

 * Arle and Akira are the only Lucky Besties to have a completely new song, complete with sung lyrics in their transformation. Both Arle and Akira in-transformation sing it before the sequence ends. They also both have idol motifs throughout their transformation performance, being more noticeable in Akira's, formatted like a music video and live performance.
