Momo steps in!

"Oh, Mei!" Momo shouted, holding up a pair of rocket boots she had made with her Quirk in the dream, and some tools. Mei's head snapped towards Momo, and she let go of Izuku, who collapsed bonelessly, swirls in his eyes.

"One of my babies!" Mei exclaimed, diving for them, and grabbing the toolkit. Almost before anyone could blink, she had the tools out, and was tinkering with the boots, muttering potential improvements to herself.

Tsuyu hopped over to Izuku and helped him up. "You okay, Master, ribbit?" she asked.

"Yeah," he replied. He then looked at Mei, and opened his mouth. "Um..."

"If you're going to explain, I'm listening~!" Mei chirped, looking at Izuku while still tinkering. "Why are we all here and naked?" she asked, not at all perturbed, merely inquisitive. "Is this some kind of Quirk?"

"Um, not exactly..." Izuku rubbed the back of his head. "So, um... Ever hear of Genies?"

"Yeah, always wanted one to wish for materials to make my babies with, and an indestructible workshop, shame they're not real... Unless you're about to tell me otherwise!" Mei remarked, never once stopping her tinkering.

"...as a matter of fact..." Izuku started, before gesturing at Momo, and started explaining the whole situation.
