This one is actually a little crossover with an Izuku from one of my all-time favorite My Hero stories, Brilliant Lights will Cease to Burn, over on AO3 that you should absolutely check out if you haven't already. It's a treat. And this won't make much sense if you haven't read it, so...if your reading this on Spacebattles, the name is a link! Yay. ON WITH THE SHOW! And yes, it is indeed a three-way crossover for the third chapter! Something special.

Izuku: You ever get that feeling of impending dread about the future?

Kero: Izuku, please get some help.

Izuku: oh, good idea! More work will distract me! Thanks Kero

Kero: izu no.

Izuku Midoriya was currently falling out of the sky above the city of Paris, and he could NOT be assed to care right now. One second he was at Watanuki's shop complaining sharing about his day and the next he goes 'You should go on a vacation' then Whoop! The tatami mat falls out like a pit trap into the open sky from a cloud.

"Bastard." Izuku didn't even try to mutter as he released the Sealing Staff, and, after making sure he had Kero who was still screaming his tiny head off at the sudden change of scenery secure, called forth The Fly.

By this point it was old hat to let the large gossamer wings lift him up and direct his otherwise fatal fall into a neat side saddle more suited to the ledge of a building than a thin stick flapping wings. Again, Izuku didn't care. he was simply staring at his surroundings with jaded eyes, already twitching a bit when he saw the EIFFEL TOWER.

"Oh, I'm going to be so annoying to him when I get back..." Izuku grumbled as he finally approached a nearby building, settling down and retracting The Fly as Kero finally adjusted himself fully, a hand over his tiny heart and gasps escaping him.

"You bet we are! he turned off my flight for a minute there! I didn't even know he could DO that! is that what you feel like all the time?" Kero gasped and thundered as his wings fluttered rabidly, hair raised like an actual cat.

Izuku, merely sighed again and stroked Kero for a minute, simply taking in the view again as he felt the fur calm under his touch, and the swearing under his breath die down as he too looked at the sights.

"At least he sent us somewhere nice. Could have just as easily been some deserted island for 'some quiet'." Izuku said after a moment, making Kero snort.

"Heh! Or, like, the Himalayas to 'chill out a bit.'" Kero shot back immediately, this time making Izuku snort.

Truly, making fun of Watanuki was always fun. Probably why they were in this mess, but damn it Izuku had to have something.

"...Want to try some of those Fancy french pastries?" Kero asked after a minute.

"Sure. Let's find a place to covert some yen. Worst comes to worse, we Fly back home. Or Erase the distance. Or Watanuki will crawl out a laundry basket or something." Izuku easily relented, already looking for the nearest foot holds and ledges to get down with while Kero floated close behind.

"Would that second one even work? I've never seen or heard anyone doing that..."

"Eh, maybe. If we get desperate enough we can try."

"True, true, for now sweets! Crepes and creams, puffs and slush oh yum~"

Ah, thank God both were so jaded by this point that a little thing like inter-continental warping didn't distract them from the real issues.

And in all honestly, it was a really easy day. It took a minute to find a place that would take Yen to exchange, and the majority of French speakers they had run into also had a good grasp of English which Izuku wasn't too bad at, and one two three he was just another tourist, if one with an odd stuffed animal.

The places were nice to be in, Kero loved the food, but things felt off. Izuku hadn't seen a single Mutant Quirked person at all so far, which while possible wasn't really likely, especially with the way they had been traveling all through the city. In fact, he hadn't really seen any sign of any Quirks outside those Superhero statues in front of that one park. It was weird, but maybe they were handled differently over here. It was a lame excuse, but if Watanuki was giving him a 'vacation' he was visibly trying not to stumble head-first into trouble again.

Oh how those words haunted him, as not ten minutes later he saw a deserted street where a Lady made entirely out of metal with a sword for an arm fought a red-clad girl with a yo-yo, barely avoiding each stab with wide leaps and parries.

Immediately he pieced together that she was some kind of fencer based off of her stance, and knew that he couldn't leave someone in help, especially a new hero from the looks of him, 'vacation' or not, even as Kero frantically covered his mouth for a moment to avoid shouting out and giving away their position.

He had taken to keeping a spare visor on his person in case of any accidents like this, but he'd need to pull up his shirt to hide the rest of his face. It would have to do.

He felt the weight of the Sealing Staff in his hand, even in its confined form, even as Kero hissed in his ear 'magic'. Because of course it was fucking magic.

It didn't change the fact that this person needed to be stopped before damage was done.

"Key that hides the power of the moon, show your true form before me. I, Deku, command you under our contract. RELEASE!" He chanted, feeling the shout echo with his power even as it drew the attention of the two previously fighting.

Izuku didn't care, as his Staff grew to its true form, fitting perfectly in his palms like part of the greater whole.

"Would you mind if I cut in? You seem to need some help." Deku asked with sincerity, already taking steps forward towards them.

"You need to get away! Qu-!" The spotted heroine tried to get out before having to bend nearly backwards to dodge a sudden swing from her opponent, who just as quickly turned back around to snarl.

"You too would dare get in the way of my fight? No matter, I'll simply deal with you both, and prove to everyone that I, Riposte! Am the greatest fencer!" The villain, Riposte, shouted as she brandished her arm blade forward.

Deku felt the frown forming on his face before forcing it away.

"Oh? Then its just as well I'm intervening. After all, I'd think The Sword would like a say in the matter as well, no?" He casually stated as he swished the Staff to the side, letting its form shatter away into the essence of Sword, its form rapier thin but strong as anything.

Both of the people in front of him were shocked, but he didn't really have any reason to think of why. He simply hopped forward with an insanely quick thrust.

The villain was only barely able to dodge, meeting blades in the center and becoming a stalemate, pushing the two close. Deku could see the shock and slight amount of fear in both how close he suddenly was and probably some other things.

"Oh, interesting. Not a lot of things can stop The Sword. That's some powerful magic you're running around with." Deku whispered to his opponent, breaking away a second later before she tried to break the stalemate, sending her to the side with, ironically, a riposte.

"You...who ARE you! That sword...I felt it! That sword..." Riposte fearfully cried out, before trailing off, staring at The Sword with something approaching lust.

"Me? I'm just the Cardcaptor here on vacation for a bit. Then I found some knit-wit who decided to run around on some kind magical revenge high and dragged in some local Heroes. And I'm not paid enough for that already back home." Deku shot back completely seriously, mostly wondering what kind of metal she was and if The Rainy could rust her...

"In any case, you wanted a strong opponent. So here I am."

"I hope you're ready for it."

END OF CHAPTER

Got really into the basis for it, which is honestly the hardest part for me. From here would be the fun stuff, which you'll see at some point probably.
