The Hero Universe. A universe where superheroes and superpowers are as common as blades of grass. However, where there are superheroes...there are always supervillains.

"Coo coo! Since the earth doesn't want us...we'll go to the moon, just like in Jules Verne's book." said the villain known as Mr. Pigeon as he and the pigeons were carrying off the Eiffel Tower.

"Okay, but how do you plan to breath in space?" Izuku said as he and some of the Hero Alliance hung onto a cable.

"Come my friends! In space, no one can hear you coo!" Mr. Pigeon said.

"So, how many times does this make it that Mr. Ramier's been akumatized?" Hope asked.

"51." Kendo said.

"Seriously? If he wasn't one of the lamer villains, that would be a record!" Kaminari said.

"Focus, everyone!" Ladybug said, analyzing the situation and finding the way to solve the problem. "I know how to use my Lucky Charm!"

"Okay but first we need to bring him back to Earth." Jexi said.

"We can handle that." Ladybug said as she and Cat Noir let go before transforming into two space themed heroes and rocketed towards the top.

Back on earth, Alya was recording everything for her livestream, the hits pouring in like mad.

"Our dynamic duo has powered up into Cosmobug and Astrocat, along with the Hero Alliance as they battle Mr. Pigeon for the 51st time." Alya said as Miraculous Ladybug was soon in effect, restoring all to normal, signifying that Mr. Pigeon was once again defeated. "They really are miraculous."

The Eiffel Tower was reset to its normal position as Jules Verne's book was placed back where it belongs.

"Once again, the day is saved, just like normal." Jexi said.

"Business as usual. Always happy to help those in need." Ace said.

"Still, Hawkmoth and the New Universal Villains must be running out of new blood to akumatize if they sent Mr. Pigeon after us." Hope said.

"Yeah… it's almost boring." Mark added.

"Even after Techno swore that vendetta after Cell was destroyed. If this is part of it, he's not doing a good job." Dan said.

"Honestly, if he knew the things Cell did, he wouldn't be acting so stupid." Saki said.

"They're a group of villains. So pretty sure he knew." Mina said.

"But why swear revenge on us? Meruem was the one who destroyed Cell." Glimmer asked.

"Remember, Meruem is a new recruit of Jump Force. And who just happens to be running Jump Force at the time?" Zoro asked.

"Oh yeah, Emi." Glimmer said.

"So, we were pretty much targeted by association." Todoroki added.

"Either way, I think we can take what he throws at us." Hope said.

"One step at a time." Al said.

"Anyway...with that done, we should be getting ready to head out. We'll be making a big trip soon." Jexi said.

"Trip? What trip?" Asta asked.

"Oh right. I didn't tell you guys. We've been asked to be hero chaperones for a special event. Meaning...a trip to New York City." Jexi said.

"New York huh? At least this one won't be in ruins." Ace said.

"It'll be good to breathe in the old city air again… well, 'bout as old as it can get in this dimension." Noir said.

"So what makes it special?" Hope asked.

"With a new order in place to keep peace between universes, it'll be a four school trip. Marinette's class will be involved along with UA, Ginhana High and the Summoners Academy in the Magic Universe." Miles said.

"Summoners Academy?" Miriam asked.

"It's the school Leonis attended in his training to become a Summoner." Hope said. "Aty told us all about it when he was still in class."

"Oh yeah, I remember her being a great help during the 2nd rift crisis." X said.

"It's a school that teaches mages to use summoning magic." Elementa said. "That's the best way to explain it."

"But why now? Why all these schools?" Kendo asked.

"Well the week celebrates the friendship between the US and France forged during the revolutionary era between George Washington and Marquis de Lafayette." Twilight said.

"Ah, I do recall him, a French Aristocrat and military officer who fought in the Revolutionary War. Also known as the Hero of Two Worlds." Jalter said.

"I know David's class is gonna attend from Ginhana, as well as Class 1-A themselves… but who's going to represent the Summoners Academy? "hope said.

"Hope...you know all of 1-A is in the alliance right?" Izuku asked.

"Well of course I...oh lord no." Hope said.

"What is it?" Leviathan asked.

"If we have all of class A...that means the class coming is…" Hope said.

"Class B. Yes." Kendo said.

"Oh, great… that means we gotta deal with him all week…." Hope groaned.

"Oh you mean that guy you mentioned?" Leviathan asked.

"Hey, don't get me wrong, Class B is cool, Kendo included. It's just that they've got one dark blemish in their roster who's always trying to berate us… that someone is Neito Monoma. Also known as Phantom Thief, the Copy Cat hero."

"I don't know which I find more insulting, his Hero Name or his quirk." Simon said. "Honestly it makes it seem like he's insulting Joker and the others having that name."

"Well, there's no way to avoid it. Let's get back to the ship and prepare for the trip." Hope said. "Heh… that rhymed."

Meanwhile at the Agreste Mansion, the New Universal Villains and Gabriel were making their own plans.

"You're letting Adrian go on the trip to New York?" Dadan asked Gabriel.

"Yes...cause we will also be going to New York." Gabriel said.

"Yeah...I know." DaDan said as a couple of Sableye walked in with a tablet. "That necklace thing on the old guy...that's a Miraculous isn't it?"

"Apparently from the reports from the Sableye Squad, it's part of a Native American Miracle Box." Pete said.

"And this one is the Miraculous of the Eagle." Boba said. "Power over Freedom. Least that's what the translation on the tablet says."

"How annoying… seems every country in this miserable dimension has magical items." Freiza said. "I suppose we're going to try and steal these as well."

"In time, but for now, the Eagle Miraculous is priority." Techno said.

"Yeah, with the failure of our new villain making experiment, we need a win." DaDan said.

"Here's hopin' those goodie-two shoe heroes stay outta our way. Our last battle with em didn't go so well.." Pete said. "Thanks ta that stupid Ant King, Cell's complelty kaput."

"...He'll pay in time." Techno said quietly, his glasses shining dangerously. "They all will."

Night fell on Paris as the group in the Galaxy King packed up for their trip. Mermista was with Leviathan as she sighed, getting all her things.

"I'm not really one for big trips to cities most of the time." Mermista said. "If you wanna take my spot for this trip Levi, you can. I mean, I am technically subbing for you in Hero Class."

"Come on, it'll be fun. I don't see why we both can't be part of 1-A, after hearing about what you did to help everyone in my absence." Leviathan said, twirling one of her bangs.

"Especially since David is probably going to be attending with his own class in the event." Tsuyu said.

"Yeah, you're probably right." Mermista said. "Honestly, the only reason I don't wanna go is to not deal with that blonde jerks annoying rants. But that's really no pliable excuse."

"You realize you're coming no matter what position you're in right?" Jiro called out from down the hall.

"I know, you don't have to remind me!" Mermista said. "Ugh, this is gonna be a long week…"

The next day soon came as the four classes selected were each boarding the appointed flight to New York.

"Okay...you can do it. Getting on a plane with Adrien is no big deal. You probably won't get lost in his big green eyes." Marinette said to herself.

"Yeah...you're really playing it cool." a voice said as Marinette saw Ginhana High's class approach.

"Oh...you guys are here." Marinette sighed in relief.

"Uh...do we know you?" Aruma asked.

"Well I know uh...David and Sachiko. Yeah. We're close friends." Marinette said.

"Hi there, Marinette. Hope you don't mind us coming along." Sachiko said.

"Yeah, the headmaster kind of insisted that Sachiko and I attend this event with our class. And for our Hero Group to chaperone us." David said. "So, how have things been?"

"You know, same old, same old." Marinette said.

"Well well, what's this? Ah...David Ishihara...so decided to drop Class A all together for a new group huh?" a voice said as they saw Class B approach.

"Oh, step off, Monoma. It wasn't my idea." David said.

"Oh and what is this?" Monoma said, holding a paper. "A survey of the school festival? And what's this? Class B beat Class A by two votes. Meaning our amazing one of a kind play trounced your little music show. Now others will know of...gah!" he said before being choked by a scarf.

"Tone it down. You'll give our school a bad reputation." said Aizawa standing behind the class.

"Hello, Mr. Aizawa. Hope you don't mind this little mix up. The headmaster kind of insisted." David said.

"It's fine. Only class B plus one other is attending this event." Aizawa said.

"One more?" Marinette asked.

"He's interested in transferring from General Studies to the Hero Course someday." Aizawa said. "So, he's been given permission to come along."

"Ah, you mean Hitoshi Shinso, the one from the Sports Festival." David said.

"Yes. I've been taking him under my tutelage to get him caught up." Aizawa said. "Events like these are a good way to see how well he interacts."

"So these are what non magical schools look like." a voice said as a number of students in robes approached. With the first one dressed in a shorter robe than the others with their hair cut short and colored a mixture of red, orange and yellow.

"So these are students from the Summoners Academy." Kita said.

"Yeah. I can feel a lot of magical energy coming from them. And that one… I wonder what his story is." David said.

"I think you mean her." they said.

"Uh...I didn't…" David said.

"Ha...just giving you a hard time. Wow...Leonis was right. You are uptight." they said.

"Can you blame me? Anyway, it's nice to meet you." David said.

"Likewise. I'm Poinsettia. One of his older sisters." she said.

"His older… Ah, right. We still remember that in the back of our minds." Sachiko said.

"So, you've been attending the Summoner's Academy yourself after your father was exposed, right?" David asked.

"Yes. Only Leonis was expelled because he knew what he was doing. The rest of us had no clue." Poinsettia said.

"Well, we won't have to worry about Copernicus anymore. He's dead. And I'm sorry for saying this about your father, but… You know, pretty much nobody liked him after that." David said.

"I respect that. And I hope you understand my reaction." Poinsettia said before slapping him. "I know all of that is true, but I still don't like hearing it aloud."

"You okay?" Ayase asked.

"Yeah. I deserved that." David said.

"Either way, we should probably get on now. New York waits for no one." Marinette said.

"Yeah, we should get on." Poinsettia said.

And so the adventure in New York soon began…
