They just needed to wait for Cirno to sit up straight and actually start thinking before speaking again.
"Oh, good morning Dai-chan." She stretched lazily while facing away from the Greater Fairy. "Was there something ya needed from me today?"
"Actually, I was sent out to find you. Sunny & the others have been looking all over the Forest for you since this morning, don't you remember? You all wanted to try working together on something today."
"I don't remember promising anything. They all need me for something /today?/"
The Greater Fairy nods while Cirno tries her hardest to remember making any sort of commitment with the Three Fairies recently. They did all have that talk with Piece by the Shrine three days ago, but...
"Shoot. I guess I just got caught up in a buncha other stuff."
"Yeah, I can see that...uh, would that also happen to involve this Human that's with you?"
"Yeah, but that's Renko Usami - the Rabbit Girl! Except she isn't actually a rabbit!"
'Obviously', Dai thought to herself. If there's anything she's learned from Cirno after hanging around her for so long, it's been how to decipher how much of what she's talking about actually happened.
"Pleasure to be acquainted I suppose. Did you just say that Cirno needs to be somewhere else today?"
"What, is that gonna be an issue?"
"Sort of, that's why I've been trying to wake you up these past five minutes! We're already halfway through the day and before I can get any major plans in order I need to, first and foremost, get back to Marisa's Shop and get my stuff. There's no way I can leave everything I've brought behind."
"So then you wanted /me/ to come along?"
"I'll need someone to watch my back if anything goes awry, or help me out if push comes to shove. Right now, you fairies are the ones with the most know-how on how to get around this area. At least to me."
"So it's almost like some kind of stealth mission? Except we're gonna be stealing back your own things?"
"Well, I, uh...not really, but if that's how you wanna look at it then—"
"Alright! I get to cover the Human on an important mission to the Forest of Magic! There's no way I can miss this chance Dai-chan, the others should already be in the Forest anyways, shouldn't they?"
"Technically, but the plan was to have a meeting over at their house behind the Shrine. If you're going with this girl instead then what do you even want me to tell them?"
The thought of having to brush shoulders with one of the few agents of power in this land who could easily send her back home without a second thought wasn't the most welcoming for the college girl, but Cirno thankfully already had other ideas to circumvent every issue all-together.

"Well then how about this: go over and tell them that we'll all meet up at Marisa's house in exactly One hour! I'll get Renko here over there safe & sound and then we can all figure something out together. That way, everyone wins!"

"Alright, got it. Are you sure you know what you're doing with this Human though? You weren't even born in the Village or anything, right?"
"Nope. Technically I'm from the country's capital but I've explored places...well, /kind of/ like this plenty of times before. I've already managed to cause a little bit of trouble but that's far from the reason why I've come here."
"She's one of those...uh, academics! Like a teacher or something."
"You mean like that lady who runs the Temple School?"
"Uh...technically I...it's more like...yeah. Sure, let's go with that for now." Renko really had no idea who they were talking about but they were at least thinking in the right ballpark here.
"See? And I'm gonna be the one to help her get back on track! You'll all see when she ends up doing something amazing."
"If you say so. I'll go spread the word then, see you two in an hour!" Renko gets ready to wave the Greater Fairy off but, before she gets the chance, Daiyousei flies close to the Physicist's ear to spread a small message of her own for good measure.

"Careful not to let her take too much credit for all those amazing things you're gonna do. She's pretty strong but a little in her own head sometimes."
"Oh, don't you worry about me. I can take care of myself if I have to, it's just nice to let her have a little bit of fun with things too if she wants to~"

Renko gives a sly wink to the Fairy while Cirno stands a few feet away, befuddled over what they could be whispering about. Daiyousei can't help but giggle behind a free hand before waving them both off herself and flying away back towards the mist. Her form seems to shimmer and dissipate into the surrounding air without a sound, leaving the other 2 girls back to their own devices once again.
"So these other Fairy Friends of yours, are they all like her or..?"
"Oh, Sunny, Luna and Star? They're all great! All fairies are different in their own ways, but they're a team that's best known for their pranking around here. They're all pretty strong too, but /I'm/ still the Strongest there is!"
