Sato Akane/Cure Aeonian/transformation

Akane needs her Fairy Letter, A to transform into Cure Aeonian by saying “Alphabet Change!”.

Sequence
A first flies up into the sky, shouts his letter and shines. He then sounds out his letter sound “ah” and dives into Akane’s Global Lua Module. Akane then calls out the transformation quote “Alphabet Change!” and taps the bottom on the bottom of the Global Lua Module. This causes the central crystal of the Global Lua Module to sparkle, and A inside gives a small jerk to bring out a golden alphabet symbol, which starts the transformation.

Akane is first surrounded by hearts, which bind together to form her dress, ending at bows at her chest and waists. Her hair changes colour and she gains her hair accessories. Akane opens her eyes to reveal that they have changed colour as well. She then forms an A shape, and ribbons wrap around her arms to form her gloves. A necklace forms around her neck. Next, the ribbons wrap around her legs, and Akane taps her feet together to gain boots.

Fun fact is the arm reveal that she does as Cure Aeonian is a reference to Aqua teen hunger force when Dr Weird does that.
