"What's his problem?"
"A toon killed his brother. Dropped a piano on his head."
- Who Framed Roger Rabbit?
Setsuna never imagined herself as a villainess. She was always a kind soul who only ever thought of doing the right thing for her friends and family for as long as she'd lived. As Cure Passion, she was the most caring and devoted member of the team and she never would have dreamed of engaging in any sort of supervillainy. Until Westar and Soular dumped a colossal basket of passiflora edulis fruit on top her.
Love, Miki, and Inori just stood there watching with confused looks and blinking eyes. Because, seriously, who tries to destroy their sworn enemy by giving them a nice housewarming present?
"Stick that up your cornucopia, Passion Punk!" one of the two Advent Children-looking dudes named after cardinal directions mocked.
What the pastel-dressed fluffy-haired heroines didn't know is that the twenty foot avalanche of fruit Cure Passion was buried under was no ordinary fruit. It was eeeeevil fruit infused with the Negative Energy(TM) of Labyrinth. It instantly started to go rotten and melted down into a blackened lump of slime and pulp.
The fruit pile wiggled as the Cure trapped underneath fought to break free. Something was amiss as Setsuna's voice could be heard sighing suggestively.
The putrefied passion pulp slithered off and gave birth to Eas. Setsuna's new makeover had shorter silver hair and alien violet eyes. Her feminine curvature was wrapped up in a glossy black gown barely resembling her Cure costume that had more scanty embroidery and exposed skin than she'd ever agree to wear in her wickedest dreams, but her mischievous smirk showed she was more than happy to slip into it now. The Advent Children had transformed her into their Advent Sister.
"That's lewd," said Cure Peach.
"How does she even fit in that thing?" asked Cure Berry. "Is that jewel thing on the front supposed to be a navel piercing or a belt buckle?"
"The dress and the ribbons look pretty. Those shorts are really tiny, though. You can kinda see her butt a little when she turns her legs," Cure Pine innocently observed. If only she had known it would be her turn to get dark and edgy in another half-decade.
Eas's spoiled personality made her cross her arms and grunt stubbornly toward her once-friends.
"I hate detestable little saps who think they're so sweet. It's time for you Cures to get crushed!"
Peach looked at Pine and Berry like "Uhhh?" Eas deliriously launched toward them in screaming rage.
Author's note: how do you like my alternate origin story, dudes?
Author's note 2: "Fujoshi" literally translates to "rotten girl." I wonder if that applies to Setsuna here.
