Clearly the best way to test this is let Oriko and Kirika hold each others Soul Gems and then walk 101 m apart.
"Well, that's the plan," Sabrina said, looking between the two girls. "It should be a lot of help in testing, and frankly, you two are some of the only megucas who'd trust each other enough to do it, so..."
The two girls looked at Sabrina, with a strange mixture of expressions.
"No."
"Yes."
"Kirika, no."
"Kirika yes."
"Why?"
"Because."
"It's useless. What would it tell us?"
"I wanna try it."
"No."
"Come onnn."
"Do you want to follow
her ideas, of all things?"
"Well, I do, so I guess that means you do, too?"
"...Fine."
Sabrina watched Oriko's body twitch for a second, before slumping... then, just as suddenly, sit straight up again. "Woo, what a rush!" she said, in a voice that was curiously off. She raised the orange gem in her hand, and smiled. "So I guess it worked, huh?"
"How does it feel?" Sabrina said, cautious but nonetheless silently cheering in her head. Cheers. The
Cheers theme. A picture of Madoka dressed as a penguin.
"It feels great!" said Oriko, as she stood from her chair... and promptly fell flat on her face. She quickly stood up, shaking her head. "Uh... sorry, sorry, I guess I'm not really used to this dress... or this weight in the front." She frowned. "It's kinda... I dunno, like wearing platform shoes and a backpack, I haven't really figured out where all my limbs should be yet."
"Well, I always was a bit clumsy."
Standing outside the yard was Kirika, straight-backed, with an unfamiliar slight frown on her face. "It is nice to have a body like this."
Sabrina stood by, seemingly taking notes in her head. "Okay, looks like you got the hang of that body quickly." Quick. Chocolate milk. Buy Mami some chocolate milk. "So, uh... alright, why not just try doing stuff, see if anything happens?"
"Oh, doing stuff," Kirika said, the disdain clear in her voice. "Truly, you are a marvelous scientis- ow!" She flinched, visibly jumping. "I bit my tongue!" Oriko rushed to the other girl's side, stumbling over the dress, as she sputtered at the sudden pain. "I thought these teeth were adorable, but - ow."
"It's okay," Oriko said hastily, hugging the other girl. "You get used to it." She grinned a familiar grin, though the effect was somewhat lessened due to the lack of the snaggleteeth that currently occupied the other girl's mouth.
Sabrina just watched the brief silence, unsure of what to say. Idly, her grief orbs began to merge into a set of Legomen. Eventually, the two girls pulled away.
"Hugging feels weird now," Oriko said, a confused look on her face that had once been utterly unknown on it.
"Height," Kirika answered back, dusting herself off. "Ordinarily, I'm twenty-eight centimeters taller than you. You probably haven't gotten used to it yet."
"Neat!" Oriko said, looking around the yard. "Hey, uh... I gotta go to the bathroom. I mean, you gotta go to the bathroom. I mean, uh..."
"Kirika, I didn't have to go before -" But Oriko was already stumbling her way into the house. Sighing, Kirika looked back at Sabrina. "She's a lovely girl, but she can be such a fool."
"Huh?" Sabrina said, looking up from her currently-in-progress one-one-hundredth scale recreation of the opening scene of a monster movie that wouldn't exist for another two years. "Oh, yeah. But that's what makes her endearing, right? That she can be so silly but still know she cares about you?"
Kirika blushed slightly, before passing it off with a shrug. "I suppose so. If nothing else, it's a good change of pace to have a fool who I appreciate the presence of." Sabrina, paying more attention to getting the details on Knifehead's arms right, simply nodded, and Kirika seemed to surrender. "She's been in there for a while," she noted. "Shall we get her, for additional science?"
Sabrina's ears immediately perked up at the sound, and she smiled. "Sure!"
"Ooh, yes, Kirika, you're very smart."
Kirika peered at the current owner of her body through the crack in the door. Sabrina looked fit to burst with giggles. Kirika just sighed.
"You're such a cutie, and you've got great fashion sense, too!"
Oriko was standing in the bedroom, in front of a full-length mirror. She'd squeezed herself into an old school swimsuit, and was currently striking poses that looked somewhere between fashion magazine and shounen protagonist.
"You're the best girl ever! Now, let's go to America, and..." Abruptly, her head turned, noticing the crack in the door. She shrank back, a massive blush spreading across her face. "Sorry, sorry, sorry, sorry, sorry, sorry, sorry, sorry!"
Kirika shrugged, and opened the door, walking into the room and putting her arm around the other girl. "Kirika, it's alright," she said. "I knew you were doing something like this. I just wish you would ask permission first."
Oriko looked up, still blushing heavily. "R-really?"
Kirika allowed a smile onto her face. "Goodness, Kirika, if you wanted to see me in swimwear so badly, you could have told me. At least then, I would have gotten myself a swimsuit that fits."
Oriko let out a bark of laughter, and hugged the smaller girl again. Sabrina, who had been watching the affair with some amusement, chose that moment to let out an
ahem. "Okay, you two, it's nice to see you're taking this well, but... there's one more thing I wanna test."
"Say no more," said Kirika, lifting the light grey gem. In a flash, her black jacket and miniskirt were replaced by Oriko's enormous white dress and hat. She lifted her arms, stretching out in the new uniform. "It feels like it always does. Fits perfectly." She conjured up one of her spheres. "And there's the weapon."
Oriko, eagerly, pulled out the yellow gem and twirled it between her fingers. The swimsuit was quickly hidden under Kirika's white stockings and black long-sleeved coat, with the claws protruding from the cuffs and the eyepatch pulled jauntily over her face. She looked rather comical, but seemed much more comfortable in the old outfit than she had since the switch. She looked at Kirika with a frown. "Aww... I don't look good in your clothes." She glanced at the mirror. "Oooh, but you look great in mine!"
"Likewise," Kirika nodded back, before turning her gaze to Sabrina. "In any case, I suppose the experiment is over?"
"Huh?" Sabrina said, her eyes refocusing. "Oh! Oh, we're still on this. Yeah, we're all good. You can go back to your bodies now. Just switch Soul Gems, then start running."
The taller girl seemed to pout. "But Orikoooo..."
"Kirika, it's fine," the shorter girl said, plucking the grey gem from her collar and handing it over, before reaching around the back of the other girl and pulling the yellow diamond. "In any case, what does this change?"
"Huh?" Sabrina and Oriko spoke at the same time. Kirika shrugged, walking to the windowsill and wrenching it open.
"We are together, are we not? My body is already yours." With those words, she promptly vaulted out the window.
"Wow," Sabrina said. "How sappy can you get, huh, best buddy?" She turned, to see Oriko standing stock still with a massive gleaming smile on her face, looking as if she had just won the lottery.
Sabrina shrugged, and muttered "Weirdos," before jumping out the window to land on a pillow of Grief.
