He does, and Izuku meets up with more familiar (one unwelcome) faces!

"Well, if I'm being honest," Toshinori replied, pulling back on his outer clothes, having stripped to his underwear for the scan. "There's a lot about my Quirk I couldn't tell you. Its workings are a mystery, even to me." That much was true, but he was selling it as him not knowing why his Quirk Factor was declining, which he did. "I'm getting weaker over time, even with the injury healed. Like I said, I'll never be back to my peak. I suppose that's the price I paid for pushing my body to its limit, and even beyond at times. That injury was just the biggest issue, I've no doubt wracked up a good deal more problems breaking my body down just from overall strain. Still, being healed brought me back up a good deal, and like you said, I'm not declining as fast as I was before."

"But physical injuries, and wear and tear shouldn't affect your Quirk... Not to this degree..." David protested, looking at the results again.

Toshinori chuckled and patted David's shoulder. "Not based on what is currently known about Quirks, true, but hey, if we did know everything there was to know about Quirks, half of your researchers would be out of a job, wouldn't they?" he asked David in hopes of diverting TOO many questions. "And some things, we may never know."

"...I suppose that's true..." David said slowly.

"Don't worry too much about me, old friend. My retirement is inevitable, but, I can manage at least another year as the Symbol of Peace at this point. Hopefully a good bit longer, that's a conservative estimate. But we're all only human, it was going to happen eventually," he added solemnly. He turned to go. "But things will be fine. I've inspired many to follow in my footsteps, and a new Symbol will rise sooner rather than later. We might hit a rough patch for a bit, but things will work out."

"...are you really certain that there's anyone who can fill your shoes? That's hard to believe," David replied as Toshinori started to walk out.

Toshinori paused at the door. "More certain than you know, old friend." He resumed his muscle form, as he was about to go out in public again. "Now then, we have a party in a few hours, let's catch up some more there!" he laughed, before leaving.

David reclined in his seat, steepling his fingers, deep in thought. One year at least... Yes, that was enough time to rebuild his device from scratch, even in secret, instead of resorting to drastic measures to get the original back. He stood, and went to find Sam. They needed to call off the whole operation they'd planned.

...

All Might stopped in the hall after a bit of walking, before pulling out the hair Izuku had given him. Time to test if the transfer would work with a hair given before One For All was processed. Izuku should be done with One For All for any of the expo games by the time he digested the hair if it did work. And it would make maintaining muscle form at the party easier, and avoid draining the embers in him for that duration. He swallowed the hair, and headed to go about his day.

...

Izuku sighed and relaxed, reclining on one of the outdoor chairs as the girls all talked. This was actually quite relaxing. Maybe he and Melissa should start looking at some of those expo games. All Might probably would have eaten that hair by now to test that idea, so he had a couple of hours left with One For All at the moment. "Here's your drink, "sir!"" someone said, putting a fancy drink in front of Izuku, who blinked. He knew that voice... He turned to see Denki standing there in a waiter's outfit. "What's up, "Mydudeia?"" he added, making a pun with Izuku's surname.

"Denki?" Izuku asked, before also noticing Mineta nearby. Oh great, he was here too... "...why are you working with the wait staff?" he asked after a moment.

"Oh, some businesses here decided they needed more workers for the expo, so Mineta and I applied," Denki stated. "We already had the temp work lined up when you made the offer to me. It was tempting to blow this off, but honestly, I felt it would be a dick move to leave them scrambling for another waiter, plus, I make a bit of spending money this way too."

"...you DID realize that the ticket I offered also had an invite to the party later, right?" Izuku asked Denki, who froze, and slumped.

"Damn it, didn't think of that part!" he wept.

"Yo, Midoriya, who's the hot blonde there?" Mineta suddenly asked, pulling Izuku down. "...you didn't get greedy and add her to your unfair harem too, did you?" he demanded, whispering to Izuku, who gave him a flat, unimpressed look.

"... she's the daughter of David Shield. The guy who's friends with All Might," Izuku told Mineta. "Who also happens to have gotten an invite. I'd tread carefully if I were you..."

Mineta froze, sweating heavily. "D-duly noted..."

"What do you two think you're doing!? Get back to work!" Iida suddenly shouted, running over from out of nowhere, causing Denki and Mineta to yelp, and hurriedly return to work.

"Oh, you're here too!" Izuku smiled, waving at Iida, straightening up. "How's your brother doing?"

"Tensai is doing quite well, thank you," Iida nodded, pushing up his glasses. "On fact, I came here with him. Good to see you here too, Midoriya."

Izuku smiled, and was about to make some more small talk, before jumping slightly as they heard a nearby explosion.
