"KITTY! WHAT ARE YOU DOING HERE!" Marinette shouted
As they were shouting well as MARINETTE was shouting and the others hysterically laughing
"Hey Mari, your parents let me in to tell you that-" ?? came clearly shocked
"YOUR FRIENDS WITH CAT NOIR?!" the unknown girl said
"We are still here you know," Izuku and Harry said in unison
"And who are they?" the Alya girl asked
"Potter, Harry Potter nice to meet your acquaintance"
"Izuku Midorya nice to meet you" Izuku and Harry introduced themselves
"Ok I'm staying I wanna know what's happening here"
Time has passed and Izuku had to go to bed and Alya needed to go
"See you at school," Alya said
"See you" Mari replied
"We have to get to bed bye Mari, bye golden," Izuku said
"Bye Broccoli/Zuku" they all disconnect from the call

The next day in Paris
"Good Morning everyone I have a special announcement, some are chosen to go to Japan!"
Ms. Bustier announced
"Isn't that the country your friend goes to Mari?" Alya said
"Yeah how surprising" Mari said
"We will go to Japna to learn about their culture and their prestigious hero school UA"
Ms. Bustier continued
"Oh wow what are the figures," Mari said kind of loud
"What were you saying Mari?" Ms. Bustier
"Sorry Ms. Im just surprised we are going to the school of my friend" Mari explained
"That is pretty amazing that you have a friend there, anyways," Ms. Bustier said continuing with her announcement
-------------------------------------------------------------------------------
In Japan
"So problem children we are having a student from Paris come here and learn about quirks and stuff," Aizawa said
"MIDOBRO WE GET TO MEET YOUR FRIEND!" Kiri shouted
"QUIET DOWN! Now for your test" Aizawa said
------------------------------------------------------------------------------------
Hogwarts
"Students to learn further about powers and their different forms we will be paying a visit to UA"
Professor McGonagall explained
"Nice" Harry thought
---------------------------------------------------------------------------------------
A/N: So for my au they have different powers so for London they think their one of those countries without magical and powerful beings, for Paris they have Ladybug and Catnoir and sometimes the other Miraculous holders while Japan is the one most open about their abilities which is quirks. So that's basically it and next chapter is a meeting of the 3 :)
