Prompt: Vert's body is downgraded to be as underdeveloped as Blanc's.
The Leanbox Basilicom was an exercise in not judging a book by it's cover. On the outside was a large white rectangular office building with green accents. But on the inside, There were living quarters fit for a queen. Neptune wondered how such a relatively drab building housed the extravagant dining room they were in.
Golden walls surrounded the giant table that Neptune and the other CPUs and candidates were seated at. Vases with ficus trees decorated each corner of the room while each of the long walls had a set a drawers up against them.
Neptune knew she was stalling at this point, a bad habit she had when things in her life had gotten really weird. It explained a lot about her actually. She looked to her fellow CPUs. Noire had her arms crossed, her eyes were closed in thought. Blanc smiled smugly and was even shaking trying to keep her laughter in. Uni and Nepgear were looking at each other in confusion. Rom wore a concerned look while Ram looked like she was about to join her sister in the laughter. Even Uzume was leaning on the table in awe.
At the end of the table, that last goddess sulked, looking at the floor with with her eyes being obscured by her blonde hair, which, while still flowing, stopped at her back. Her green princess dress looking completely different on a smaller frame. Unfortunately, the dress was the only thing that fit, and even then it had to hemmed up.
"Miss Vert?" Rom asked, breaking the silence, "Did someone poke you with a needle?"
Blanc couldn't take anymore as she burst out laughing. Falling out of her chair as she was consumed in giggles, Ram following soon after.
"I fail to see the humor in this," Vert spoke before wincing, "Oh dear, even my voice sounds younger…"
"Heh… Heh… Call it Karma, Thunder Tits…" Blanc paused in thought, "hehe… Guess I can't call you that now."
"How did this even happen?" Noire asked, "People don't just change overnight!"
Neptune and Nepgear looked over to Uzume. Uzume squeaked in surprise.
"What are two looking at Uzume for?" She asked in her 'Dream Voice', "Why would Uzume want to turn Vertsy into a Loli?"
"Uzume, please…" Vert pleaded, looking back at her lap.
Uzume realized her slip and coughed into her normal voice.
"Besides, my daydreaming powers don't work like that anymore. Most I can do now is predict when pudding is gonna be on sale."
"You can do that?" Neptune gaped, "Yooo, Uzume, we need to talk!"
"Neptune!" Noire yelled, "It's not a good time to be having stupid discussions!"
"To answer the first point," Vert said, also wanting to get back to the subject at hand, "I just woke up like this… Chika discovered me… and here we are…"
"Hopefully she and Histy came up with something," Nepgear said, "I hate seeing Vert sad like this."
"Oh, Nepgear, my dearest little sister! I knew you'd understand my plight!" Vert exclaimed as she tried to run into the lilac haired girl's arms, only to trip over her own dress.
Neptune supported her head with her arm on the table, "You know, I would get mad at you trying to steal my little Nep from me again, but now it just seems beneath me…"
Vert whimpered as tears welled in her eyes.
Before anything else could happen, the doors to the dining room opened. Leanbox's Oracle, Chika Hakozaki strode in with Histoire floating in close behind her. She stopped when she saw Vert on the floor.
"Vert, honey, what are you doing on the floor?" Chika asked in a motherly tone, The other CPUs going wide-eyed at that.
Chika helped Vert on to her feet and guided her back to her chair. Vert sighed in defeat as she got back on to her seat.
"We've looked into the matter thoroughly," Histoire announced, taking a place to Vert's left as Chika stood to Vert's right.
"We found the apparent cause of this transformation," Chika continued, "... and it's…. Strange…"
"How strange is it?" Neptune asked, "If it's Big Adventure Strange, the the author should really know better than to start a new project-"
"Neptune, please!" Histoire commanded, "What has happened to Vert is perfectly natural"
"Excuse me," Vert Piped up, "But how is this natural"
Chika smiled and patted vert on the head, Vert groaning at the gesture.
"Well, it is strange… but I looked over the Leanbox Census, and it seems our citizens have started to prefer… a slimmer CPU…"
Vert looked at Chika, her eyes forming blank white circles, "... What?"
" It would seem that Leanbox's Sharicite wanted to conform to the people's wishes. Usually that would be the point when a Candidate would be born, but since the Sharicite is still unable to support two CPUs…"
"It… Changed ...Me" Vert completed, her stare looking into a thousand yards beyond the dining room.
"It can do that!?" Blanc gaped.
"It… Stands to reason, I guess…" Noire reasoned, " We do reflect our nations as CPUs…"
"Huh, you think if Big me becomes super popular on planeptune, I might grow up into her?"
"So… I'm stuck like this?" Vert asked, ignoring Neptune's attempts to derail the conversation.
"I'm afraid so, my darling little sister." Chika said, squatting to meet her at eye level.
Vert's eyes went blank, " Little? …. Sister?"
"Well how can I resist!" Chika gushed, "You are so adorable Funsized! I never really saw the appeal of little sisters, but seeing you like this just makes me want to hug and protect you!"
"Chika…" Vert whined.
"We do need to get you some new clothes… Wait! Let me clear our schedule, the rest of the day will be a Sister Shopping day!"
"Girls," Vert Pleaded, " Please help…"
"Well I guess that settles our business here, don't you think?" Noire said, standing up.
"Yeah, we know better than to mess with Sister time!" Neptune added .
"Traitors!" Vert gasped.
"Bye, Vert, hope you enjoy your shopping trip!" Blanc sang as she took the twins hands.
Thus, all the CPUs left the shrunken goddess to be aggressively doted on by her Oracle.
