Katana blocked a punch before kicking her in the stomach. Anna was quick enough to move and counterattack with another punch. As Katana stumbled back, Anna grabbed her and tried to lock her arms in, but little did she know it was part of Katanas plan. When Anna rushed into locking Katana in, Katana simply tackled her to the floor, winning.

"Yes! I can't believe I finally won over you!" Katana said getting off her sister and helping her up.

"I'm tired from this mornings' sparring so don't get your hopes up of being better than me." Anna said annoyed.

"Yeah yeah." Katana said rolling her eyes before laughing.

To try and lighten the mood, she splashed a little water on the green eyed girl next to her.

"Katana!!"

"Relax, it's just a little water. Not so different from the sweat we're covered in." the white haired girl joked.

Anna rolled her eyes before laughing and joining her sister out of the gym.

Before they could go into their rooms, their father stopped them. He had a serious look on his face, a more serious one then usual.

The girls stopped and listened closely to what their father had to say.

"My girls, I'm glad you've been training hard lately. The mission I told you about, in Musutafu, is taking place tomorrow morning. Someone will bring you necessities before you leave. I do not have time to see you before you leave since I'm going on a mission myself. I just wanted to say good luck, and to get some rest." he said.

The girls didn't even say anything back, they just ran towards their father and gave him the biggest hug. They knew the missions they were going on tomorrow were more dangerous then the ones they've went on before, so they needed this.

All 3 of them needed this.

Just as the sun was starting to go up they left their home In the mountains and began their journey to Musutafu. It was going to be a 3 day travel.

"So about this mission, Anna." Katana said.

"Who exactly is Shigaraki?"

"He used to run this organisation called the league of villains. After they got busted he and some creepy girl somehow escaped and he created a 2.0 version of it years later. We're basically here to stop it since these quirk having so called "heroes" don't do anything about it."

Katana didn't say anything. She knew this mission was going to be hard not only because of who they're up against, but because that whole city is full of heroes. Anna and Katana were the only two in the family with quirks along with a few other assassins.

Quirks were not allowed to be used after an accident occurred where their great grandfather lost his family because a hero used his quirk to make a building fall to take down a villain, not noticing the woman and child in her hand right under the collapsing walls. He took his newborn baby boy and moved somewhere far far away. He stumbled upon this giant place where he was greeted by the woman in charge herself. They fell in love and a few generations later Anastasia Akito was born, who later found Katana.

Katanas quirk is copy. That means she can copy anyone's quirk just like Monoma. However their time limits work differently. Depending on how much of the power she uses, the time limit is different. If she for example uses a little bit of power, the quirk stays longer and vice versa. If she doesn't use the quirk she had copied, eventually it just runs out since it's not really part of her.

She doesn't know how many quirks she can copy at once, the only time she's tried it was with Annas quirk and accidentally on some random person she bumped into in the halls.

It was a powerful quirk yes, but Katana doesn't get to use it very often. Ever since her father took her in she's been trained into the assassin she was meant to be with the katana as her main weapon.

Anna's quirk is dizziness. She can look into someone's eyes and instantly make them feel dizzy and create the feeling and illusion of a room spinning around and around.

Katana has been on countless missions alongside her family, doing what the heroes of Japan can't do. And they do it without quirks and fame. Just because they were assassins it didn't mean they were bad people and killed innocent ones. It's just that they get the job done faster and smoother by simply killing their targets.

They finally arrived in the city of Musutafu. It was a very busy city, people walking on their way home from work, traffic jams and heroes patrolling the streets. It was almost nightfall, which meant the mission was taking place soon.

Katana, Anna and a few others were on a rooftop ready to bust in through the window across the street.

"Wait for my signal." Anna said, right before gesturing with her hand to move.

They started to fight with some low life criminals in their way.

"Take care of them!" Katana shouted and started to run up the stairs after the big fish. Anna followed shortly after.

Katana kicked a door open and found herself on the rooftop. A few meters in front of her stood a skinny man dressed in black. He didn't even flinch when she kicked the door.

She threw a small knife towards him which he quickly caught and turned into dust.

"So that's your quirk? Huh." the blue eyed girl said as she smirked.

He slowly turned around to reveal his face that was covered in a hand. Anna came sprinting up, stopping when she saw that Katana wasn't moving. She looked in front of her and saw the man they were after.

"Yikes, what crawled up his ass and died?" she asked, looking at Katana.

They both nodded, had determined smiles on their faces and leaped forward attacking the villain in front of them. He swiftly dodged their attacks, taking out Anna's staffs so that she had to fight with her own hands.

They only fought for a short while, he wasn't too much of a challenge all alone like this.

And just as Katana was pinning him against the ground with a knife in each of his hands about to finish him off, a loud explosion was heard nearby.
