Chapter Text
Millie Parfait missed using her magic thus she's learning alchemy as of late, trying to enhance her witch skill. She has been immersed into learning new potions recipes and was trying to create a new one herself.
Since Millie is a petite witch, she kinda imagines herself as a hot mommy like Nina. Thus, she came up with the idea of a growth potion, one that will help her grow into a fine woman like Nina but still remains her beauty.
Millie finally managed to create one; a prototype growth potion and wanted to show it to the rest of Ethyria by testing the potion on Enna's cactus plant. If it works, maybe she will ask in Enna and Reimu's opinion on whether they wanted to join her in the transformation.
When Millie finally came out of her basement lab after shutting herself in for a week, running to the living room where the rest of the Ethyria usually are, she failed to notice the shopping bag that was placed on the floor which resulted in tripping over. Her precious potion on the other hand unfortunately slipped from her hand and spilled on Mysta, the guest of Ethyria household for the day.
"Oh Millie honey, are you okay? You finally come out!" Nina stood from where she was seated and tried to help Millie stand up, failing to notice what had happened to Mysta.
"Naurrrrrr!!!! My precious potion!!!!" with watery eyes, Millie screamed. Mysta on the other hand was confused. He lost a bet on last night's collab stream where they bet who would lose that one uno game would accompany Nina shopping, being her assistant for the day. Of course, our precious fox detective lost miserably and here he was, just came back from 7 hours of torture carrying the result of Nina's lust.
"What do you mean-!!!! Oh my god, honey! You're all wet!" Nina finally noticed what had happened to Mysta and rushed to the bathroom, trying to find a fresh towel to wipe off whatever liquid that suddenly showered Mysta.
"Millie, what is this? I'm all wet and sticky and- Yucks!! This smells horrible. Urghh!!" Mysta clearly wasn't pleased with what was happening.
"It's my new masterpiece you dickhead! Don't call it horri- Wait!" Millie's big brain suddenly popped out a brilliant idea. "Hey Mysta, try licking it. It's actually a growth potion that'll help me be a drop-dead beauty like Nina. Why don't you try it too? Maybe you'll look more pog than Luc-"
Millie couldn't finish her words when Mysta already licked the remains of the potion that was sticking on his hand.
"Mysta… I…. I didn't… Expect you'd try it without arguing with me…. T-This is actually just a prototype that I planned to try on Enna's cactus." Shocked by Millie's statement, Mysta froze up.
"YOU WHAT??!! OH MY GOD, AM I GONNA DIE??!!! MILLIE TELL ME, AM I GONNA DIE?!" Mysta clearly was panicking, checking his body to see whether anything strange had happened yet.
It didn't take long before the potion took its effect, making Mysta feel sudden adrenaline rushing through his body, his throat felt like it was burning, and that honestly scared him. He looked at Millie with a terrified face, eyes all teary while both of his hands clutched the fabric of his shirt on his left chest side, completely horrified with his abnormal heartbeat.
"Millie, tell my mom I love her pleas-"
Thud
"Mysta, use this towel to- OH MY GOD WHAT HAPPENED, MYSTA!!!" Nina rushed to Mysta's side, wanting to check on Mysta, only to be blocked by Millie.
"Nina, I- I think it's wise for you to put on gloves first," Millie shuttered a bit but managed to say it. She knows that one should consume the potion for the effects to kick in but it's better to be cautious by not having direct contact with it.
"W-what do you mean Millie?" Nina tried to hold her composure, nothing can be sorted out if everyone is panicking.
"T-This… this is actually my new potion and Mysta licked it out of his hand. I don't mean to scare you Nina but please," with shaky hands, Millie still holds Nina tight. By now, she was already dropped on the floor, unable to stand with her shaky legs. She's terrified too as she didn't mean to test it on Mysta. Millie is a proud witch, she knew that she'd not fail. However, seeing her friend's horrified face because of the potion's effect, HER potion, she'd be lying if she ever said she was not scared. She's not a damn inconsiderate witch who would test her prototype on an actual human being, especially on her dear friend. Looking seriously deep inside Nina's eyes, she pleaded,
"..please.."
Nina saw the fear in Millie's eyes. Nina knows well that she treasures all of her friends dearly and having an accident involving her friends as a result of her negligence is the last thing she'd want to.
"Okay honey but at least let me look at Mysta either he's breathing fine or-" as Nina and Millie turn to look at Mysta, both of them froze up. Nina couldn't finish her words, while Millie lost her strength to hold onto Nina's arm. They couldn't believe their eyes.
Mysta Rias, our proud and precious fox detective, one of the chaotic members of Luxiem, had turned into a child.
