It was a new age for humanity. People had started developing extraordinary powers with no apparent explination over a century ago. These abilities were dubbed 'Quirks' and the world soon had to adapt to this new breed of humans, for with the rise Quirks came a new type of criminal activity and the need to counter those individuals. Now over 80% of the population are born with unique Quirks and a career thought only to exist in comic books became reality.

"Well, I've just stepped into Japan, and already the hero business is different," commented a blond, American teen girl walking out of Tokyo International alongside a lanky Japanese man.

"I'm honestly surprised that your Junior Hero license is valid here, Ailene," he said while flagging down their ride, another friend of theirs. "High school kids don't get those until their second year or later."

"It might be because I'm listed as a combat medic, Jojo." They loaded her luggage into the car and got in. Soon they were riding into the chaos of Tokyo traffic.

"Remind me why you're a YouTube star going for becoming a hero?"

"Because I want to actually help people in real life and not just over the web," was her answer. Ailene Keli Smith was a big YouTube star back in America, mainly for being an entertainer with beautiful content and some serious toned to light hearted vlogs. Why was she in Japan? She was a foreign exchange student about to attend U.A. Academy, the place where the most famous heroes learned their trade. "And YouTube ain't consistent enough to pay bills."

"Okay, fair enough," Jojo chuckled. Once they arrived at Jojo's apartment and got her settled in, Ailene checked in with her father and reassured him she had made it to her destination safely. Lo and behold, just as she hung up, the door bell rang and her friend opened the door to find two police officers standing there, looking apprehensive.

"Is a Ailene Smith-san here?" one of them asked.

"Yes, sir," she stepped up beside Jojo. "Is there a problem?"

All Might was unsure of this. They had the location of the League of Villains and a secondary location, they had a solid plan, and now the team consisting of seven pro heros were waiting for the last member to arrive. That person is what made him unsure.

"I don't like this one bit, Tsukauchi," he told his friend in the police force. "We're putting a foreign hero's life in danger with this. Plus, she's a student at UA, with her safety entrusted to the faculty and her host family while she's in this country; wouldn't America be in an uproar if she got injured?"

"As much as I don't want to do this, I have no say in this," the detective replied. The other pros were starting to get curious about this newcomer. "Both governments are in agreement as well, especially if he makes an appearance. Recovery Girl won't be able to help out much with how many casualties we'd be facing."

"Just who are you two talking about?" demanded Endeavor, the flaming hero with the sourest attitude on the planet.

"They're probably talking about me," said a young woman, gaining everyone's attention. She was for sure a teenager, wearing a green, form fitting outfit similar to a ballet leotard with a skirt and a belt with medical supplies strapped around her waist. Two silver braces with large quartz gems and designed to look like butterflies gleamed on her wrists, and several more adorned her butterfly mask accenting the patterns carved into the metal. Her hair was tied up in a French braid with her bangs framing her face. "It's a pleasure to meet you all, my name's Shamrock and I do hope you won't need my services or my Quirk tonight."
