Chapter 77: Momo: You, Go Date My Brother-in-Law.
....
"Complete!!"
Lala gazed with overflowing joy at her two new inventions resting on the desk—identical in shape save for their colors. The blue one on the left was a spray that forced one's personality to become completely straightforward, while the right one was the breast-enlargement spray Nana had begged her to develop.
The development of the former was quite simple: through specific chemical reactions, she produced a liquid agent that temporarily altered one's personality, then loaded it into a spray bottle.
The latter, however, had caused Lala to rack her brain for two solid days during the design phase. Breast enlargement remained an enduring medical cosmetic topic throughout the galaxy, ultimately split into two major factions by scholars:
The "Natural Faction" and the "Potion Faction."
The motto of the Natural Faction was: utilizing various foods and exercises that promote physical development to spur a third wave of development for the chest.
Although following this approach resulted in the vast majority of female members ultimately developing firm pectoral muscles—with only a minor fraction of exceptionally gifted girls achieving a transformation from flat-chested to mega-busted—it nevertheless provided powerful proof for the Natural Faction's doctrine.
The approach of the Potion Faction was far more aggressive than the Natural Faction. As long as it enlarged the chest, breast-enlargement potions and surgeries were embraced indiscriminately. Thanks to rapid results and short timeframes, it earned the fervent backing of countless females across the galaxy.
Yet beneath that glamorous transformation lay the tragic, deceased remains of many who suffered from severe sequelae left behind by potions and underground surgeries.
Lala's exact predicament lay in wanting to fuse the two together—creating a breast-enlargement agent that wouldn't harm the body, yet produced quick results in a short span of time.
Huddled in her room, pondering back and forth with zero leads, she had no choice but to run off to find Kihara for some late-night exercise to relax herself.
Drenched in delicate sweat as she rested her head on his sturdy arm, Lala asked him about the problem she was facing in an appropriate manner, ultimately receiving a brand-new line of thinking.
"Why are you trying to create something out of nothing? Wouldn't it be easier to just borrow from someone who already has it to spare?"
"Oh right! That works too!!"
Lala bounced straight up in excitement. Basking in the moonlight, she enthusiastically greeted Kihara.
Just as she prepared to get up and return to her room to continue developing the breast-enlargement agent, her slender waist was wrapped tightly in an embrace.
"Looks like I helped you solve a problem. Shouldn't you give me a proper reward?"
"That's true." Lightly stroking the tips of her hair, Lala raised her eyebrows slightly, a smile gleaming in her emerald eyes. Like a gentle breeze, she sank back into Kihara's arms. "Tomorrow I'll go to my room and grab a bottle of Lalette milk for you! It's super delicious~"
"Is that your idea of a reward?"
"Do you not like it?" she asked back innocently.
"I like it, but... I feel like giving me another kind of reward right now is far more suitable..."
"Oh! So that's what you mean! Sure thing!"
After the two spent a lovely night together, Lala returned to her room, spending a few more days following the train of thought Kihara had provided until she finally created the breast-enlargement agent Nana so desperately craved.
Strictly speaking, this wasn't a genuine breast-enlargement potion. It merely automatically transferred bust volume from surrounding females onto the target whenever the gadget was activated, temporarily turning her mega-busted.
To put it bluntly, the effect was more like a "Mega-Bust Trial Card."
Gadgets that directly altered the body carried immense risks; Lala didn't want her younger sister's body to suffer harm, so she chose this method to relieve Nana's "bust anxiety."
"Aah~~~ I suddenly feel so tired... Let me sleep for a bit..."
The moment Lala finished stretching her arms, sleepiness blanketed her brain completely. Her eyelids fought a heavy battle, looking as if she might fall asleep standing up in the next second.
Before sleeping, forcing open her heavy eyes, she slapped pre-written name tags onto the two new inventions, leaving behind a scribbled note as a reminder before diving into her soft bed to journey off to dreamland.
...
Receiving a text notification from her big sister, Nana took advantage of Momo inexplicably clinging to Kihara's side to learn cooking from him, tiptoeing up to the attic and into Lala's room.
The moment she stepped inside, her eyes were drawn to the two differently colored bottles on the workbench. Spotting the words [Instant Enlargement Spray-kun] printed on the blue bottle, her body shivered in sheer excitement.
Fortunately, Nana noticed Lala fast asleep in bed, exerting every ounce of effort to suppress her urge to cheer. Tiptoeing over, she cradled the bottle in her arms like a precious treasure. Catching sight of the small note on the desk out of the corner of her eye, she looked down to read it.
[Nana, please give the other bottle, 'Courageous Straightforwardness Spray-kun,' to Momo for me. Just tell her it's a spray that lets a person speak their mind directly.]
"Hmm? What does Momo want a spray like that for? Don't tell me she plans to use it to prank me?"
Nana pondered with knitted brows for a moment, deciding her guess was a bit too absurd. Aside from matters concerning Kihara, she spoke her mind directly on a daily basis anyway; the spray was basically useless to her.
"Whatever. Since I know what this spray looks like in advance anyway, even if she really tries to prank me with it, I can prepare beforehand."
She casually stuffed the pink bottle into her pocket—devoid of the careful gentleness she used when holding the blue bottle—stepping out of Lala's room softly. When Momo walked into the living room to drink water, Nana shoved the spray straight into her hands.
"A new gadget from big sister? But I never begged her to make something like this. Are you sure you didn't mix things up?"
Eager to head back to her bedroom to test the effects of the breast-enlargement spray, Nana had zero time to slowly explain to Momo, forcefully shoving the pink spray into her hand with impatience.
"Geez, I told you she specifically asked me to hand it to you! How could I mix that up? Just take it quickly!"
"Fine then. I'll ask big sister for clarification after I finish cooking."
"Don't. She's sleeping right now; developing gadgets must have exhausted her. Just let her sleep until she wakes up naturally."
"Understood."
Momo had no choice but to tuck the gadget away in confusion. It was only when she visited Anna Yanami's house as usual and listened to the girl spouting all sorts of defeated-heroine rants and cowardly maneuvers that realization dawned.
She gradually understood everything.
'So big sister wants me to use 'Courageous Straightforwardness Spray-kun' on Anna! Could she already know about the Harem Plan?'
'No, no, no! There's absolute zero chance she knows. She must have merely guessed Anna's feelings, which is why she gave me a gadget like this.'
Anna Yanami, who was busy pouring out her bitter complaints to Momo, suddenly noticed the other girl's brows tightly knit as she muttered softly to herself, waving her hand curiously in front of Momo's face.
"Momo, what are you saying?"
"Anna..."
"W-What's wrong? Why such a serious tone all of a sudden?"
"Tomorrow, you are going to ask my brother-in-law out to the amusement park."
"Ah?" Anna Yanami's eyes widened in sheer disbelief, her index finger pointing directly at herself: "ME???"
