Melissa takes them on a tour while All Might catches up!

"Hey Melissa?" David said after a few minutes of conversation. "Would you mind taking All Might's... plus eight on a tour through the expo? They're probably excited to see the sights, and I'd like to catch up with All Might a little bit."

"Of course, Dad!" Melissa nodded. "I'd be happy to show what we have acheived to future Heroes, and a fellow inventor!" Izuku and Mei showed the most excitement as they headed out.

"Sam? You should also take a break," David told his assistant, who nodded, and left as well. "...you doing alright on time, Toshi?" David asked as All Might steamed slightly, and reverted to his thinner form, but he wasn't strained about it.

"I could actually have gone a good bit longer, but it's good to relax the muscle form regardless," Toshinori chuckled. "It's gotten much easier, given recent developments..."

"What developments?" David questioned, before Toshinori pulled up his shirt, revealing the greatly reduced scarring, and he widened his eyes. "Toshi, what happened to your injury? There's still a scar, but it looks far better than it should!"

"Yeah, someone with a truly remarkable ability actually fully healed it. I have my stomach and lung back, and the tissue damage has been reversed completely, save the small reminder," Toshinori explained, deliberately wording it vaguely to avoid outright lying, and using the word "ability" instead of "Quirk." Obviously, he expected David to assume the latter was what he meant. "Sadly, the one who did the healing would rather stay anonymous. I'm still far from my heyday, but I'm doing much better than I was about a year ago. And I've actually started being able to put on some weight in this form as well."

"I... I see. That's wonderful news!" David replied, grinning like a fool. Maybe that **** idea Sam had given him wouldn't be necessary. "Still, would you mind if I gave you a look over in my medical lab? Make sure everything is working as it should? You never know how the human body can respond to such things."

"But of course, old friend!" Toshinori laughed, following David. Still, he would proabably have to still explain why his Quirk Factor was dropping, but he couldn't very well refuse. At least the hot potato game he was playing with Izuku would mean it would be higher than it would have otherwise been so maybe he could just sell it as him getting older, and still accumulating wear and tear.

...

Izuku and the others followed Melissa around, except for Inko, who decided to check into the hotel ahead of them again, Izuku and Mei both gushing a bit at how amazing the artifical island really was, though Mei needed to be tied up again to avoid getting Melissa sidetracked with her interrogation about the nanotech. Izuku further gushed when he saw the Kaiju Hero, Godzillo. "Wait, so is that a Mutant type, or a Transformation Type?" Itsuka asked curiously as she looked up at Godzillo as he passed by, letting Izuku fanboy in peace for the moment.

"...Mutant type, which means he permanently looks like that, hence why he usually only operates in rural areas," Momo answered. "That's why despite how iconic his Quirk is, he's not exacly high up in the rankings..."

"...dear Lord, his poor mother," Setsuna cringed. Fun fact, while Emitter and Transformation Type Quirks usually manifested by four, Mutant Types almost always were apparent at birth.

"No, I'm pretty sure he was a normal sized baby, but grew rapidly after birth, that's usually how it goes with Mutant Types that are larger than normal humans," Momo chuckled. "I still would go with a c-section though, on account of those spine plates..."

"Oh, Deku, you and the others should definitely check out this building!" Melissa pointed, referring to Izuku by his Hero name for now. "It's where we keep the latest declassified completed projects soon to be available to Pros!"

"Oh, that sounds amazing, I bet Mei would... where did she go!?" Izuku yelped, staring at the pile of rope next to Itsuka, who also just noticed that Mei had gotten out of the rope.

"WAIT FOR ME, PRECIOUS BABIES! THIS MOMMY NEEDS INSPIRATION!" Mei shouted gleefully as she made a beeline for said building, leaving a dust cloud behind her.

"...Itsuka? How did she get out of that rope?" Momo asked with a heavy sweat drop. "I made that thing strong enough to hold Izuku, for crying out loud!"

"I don't know!" Itsuka wept comical tears. They quickly moved to follow Mei.

(That last part is a bit of an obscure reference, lol. It's from a fanfiction from a while back I enjoyed. A whole plate of cookies for whoever recognizes it!)
