Got autistic, made a greentext story.
>"Sui-chan is...!"
>"Small today too."
>Sakura Miko's words enraged Hoshimachi Suisei beyond belief.
>She was plenty of things - beautiful, talented, hard-working, with a voice like honey...
>But small? Perish the thought.
>Suisei cupped her chest as she looked in the Hololive dance studio's standing mirror, gyrating her palms around the fabric of her top used in dance practice.
>"They're decently-sized! Damn that Miko! She's an airhead!"
>She unzipped her shirt's sideways zipper over her chest, exposing the cleavage window.
>"There's a pronounced cleavage here! The zipper window makes it stand out more!"
>"Snkt...!"
>At the sound of snickering, Suisei turned around.
>Hakui Koyori stood there holding a cooler in her hand, with another to her curled lips.
>Her tail whipped from side to side in giggly emotions.
>And her large cleavage was peeking out from the bikini top she exposed under her jacket.
>Suisei folded her arms in frustration at the ribbing.
"Koyo-chan, what do you want?"
>"Just practice. And I wanted to test a new supplement out too, using the studio mirror."
>"Supplement?"
>Koyori opened her cooler, setting it to the floor, and revealed the contents within.
>Glass bottles of milk, print with cow patterns, and the small picture of a certain knight on the cap.
>"It's Koyo-chan's newest concoction - Knightly Milk: Boingy Boingy Mk. II! Noel-chan helped me with it!"
>"'Boingy Boingy'?"
>"Indeed, it contain's Noel-chan's spirit and vitality, and it'll help with boosting your physical features. I was going to try it on myself first, but you might be the better subject, considering...!"
>Koyori stifled back a laughter, as Suisei looked down at her plank-like physique, and small mound of a cleavage.
>Her face flared pink.
>"J-Just let me try one...!"
>Suisei took a bottle from Koyori and downed it in one gulp.
>Observing herself in the mirror, Suisei felt a mighty spirit spread through her chest, and felt it swelling into her breasts.
>The mounds grew slightly, pushing her top forward to a size just under genmate AZKi's.
>"...That's it?"
>"Limited effect, but an effect nontheless... This is good data I can use! Thanks for the test, Sui-cha-"
>"Another."
>Koyori threw back her head, not expecting Suisei to be so zealous.
>"Another? A-Alright, Sui-chan, but don't be so over-"
>Suisei grabbed the milk from Koyori's grasp and downed another, letting a gasp for air escape her lips.
>The energy coursed through her body, but her chest didn't appear to get any bigger.
>Her height instead began to rise by a few centimeters, much to Koyorj's surpise.
>Suisei's clothing shrank and tightened around her growing frame.
>Frame that Suisei herself didn't notice, with her eyes laser-focused on her chest.
>"They're still the same! Gimmie another!"
>"S-Sui-chan, you grew! I-I really don't think any more is a good ide-"
>Suisei bowled over Koyori and furiously rummaged the cooler, grabbing three bottles between her fingers and slipping their uncapped necks past her lips.
>"Sui-chan, no!!"
>Suisei finished the bottles and threw them aside, before looking down at her chest.
>"Come on, come on, come on!!"
>Suisei could feel her chest swelling against her cupped hands.
>Her flesh-mounds pressed out her shirt as she felt her fabric tighten between her palms and breasts.
>"Yes!"
>Suddenly, a rip. And then another.
>Suisei felt her clothing start to tighten hard around her body.
>The elastic waistband of her training pants tightened hard around her hips, like a twisting rubber band on a finger.
>Her sneakers shrank against her feet and frayed at the seams.
>The zipper on her shirt shot off her chest and cracked the dance studio mirror ever so slightly.
>"Wh-What?!"
>Suisei fell to her rear, and began to notice from the floor shifting under her buttcheeks, filling out her pants, that she was growing in size.
>The world was shrinking around her, and fast.
>Koyori flew into a panic, and quickly broke for the exit.
>"Koyoh-no! I'm outta here!"
>"W-Wait, Koyo-chan!!"
>Suisei's growing sprang into overdrive, her shirt, pants, and shoes exploded to tatters around her body.
>Suisei's bra broke apart at both the front and back clasps, and her panties snapped and were consumed by her expanding crotch.
>Suisei shrieked as she blew through the numerous floors of the studio, her head smashed through numerous ceilings.
>Long locks of comet-blue swept through each floor of the studio as Suisei went through the building, catching other Holomems on other floors like a fishing net and dragging them upwards with Suisei's expanding form.
>The studio building broke apart with a massive explosion, like an egg, hatching a gigantic, naked Suisei, whose extremities were covered by rubble.
>Somewhere, Yagoo shed a tear.
