Hey there guys, thank you all for the massive support and likes in the last chapter. I am glad that people enjoy this idea. I mean I really like Yor she is one of the sweetest characters in anime despite being a killer. This is fic is mostly focus on her side and how we deal with an assassin literally working at UA. Remember that UA has some of the worst security system in anime.

At a five-start hotel in Tokyo.

The entire penthouse was rented by a man called Raiden Kyou. He is a powerful and rich businessman, but what most people don't know is that he is also a supervillain called ´´Wreckus´´. With his quirk of shake he could do vibrations powerful enough to destroy entire buildings and this was his scheme. He would act as Wreckus, attack poor areas and use his quirk to destroy the houses then buy from the owners, remodel and then sell those for a fortune. He has been done that for years and nobody has ever noticed the similarities between the two.

''Hurry up, we need more blueprints here! I want this next house plan to be ideal one for those suckers.'' Said Raiden to his underlings.

''Yes sir!'' Said the men.

''Make sure to not let anyone come here in this floor. I also hired a girl to come later. You will know her…she has feathers.'' Said Raiden with a smirk at the end.

''Yes boss.'' Said the security.

The men did their job. Protecting their penthouse for their boss. None of those man were honest or wanted a clean job, that was pretty much a crooked mafia down there.

A few minutes later someone reached the penthouse. It was a woman but something seemed odd about her.

The woman was wearing a beautiful black dress that extended to what looked like a red cape. It was showing off a good part of her skin, but there was also her face which was covered by a black mask with the look of a fox.

''Sorry lady this area is closed.'' Said the first guard.

''Hey is that the girl?" Asked the second guard.

''Well she doesn't have feathers.'' Said the first one.

''Why the boss has that fetish?'' Asked the first one.

The woman just walked calmly towards the two guards. No fear present in her body as the two were ready to raise their guns. However in the way towards the door she stopped walking and just stood.

''Uh?'' Asked the first guard.

In a matter of a millisecond the woman took out two golden stiletto and charged at the two with immense speed. Stabbing the two men in their necks.

STAB

''Argh!'' Said them in pain.

Soon she charged towards the main room and busted the door.

Boom

''What is going on?" Asked Raiden.

''it's the Pro heores!'' Said one of the henchmen.

''No…its not them.'' Said a cold and almost mechanical voice.

They all saw the newcomer. She was looked like a sexy grim reaper as she was covered in the blood of the security guards that she just killed.

''Are you Raiden Kyou? Scum that try to act as a noble business but its just a shameless villain?" Asked the mysterious woman.

''Who are you?" Asked Raiden in horror.

''I am terribly sorry but…I will be taking your life.'' Said the woman.

This was an elite assassin from a private organization. They were tasked to eliminated villains and corrupted people that tried to act as noble in Hero Society. This woman was one of their youngest members but one of their best. Her codename Thorn princes.

An hour later

The hotel room was pretty much left with a bunch of corpses all laying around. Everyone was dead. Raiden included as he was stabbed multiple times in the chest and in the throat. Thorn Princess was on the restroom of the room washing the blood in her hands, she even took off her mask that concealed her voice and her DNA from tracking devices so she could breathe some air. The super assassin was none of other than the sweet secretary Yor Briar from UA.

Yor Briar was the Thorn Princess. She gained the nickname because of her weapons that looked like thorns and her super skilled abilities. She didn't become an assassin because she wanted this life, she became one so she could sustain her little brother. However even after her brother grown older and went off she stay as an assassin because she felt she was doing good in the world. One thing that her organization thought her well was to leave no traces behind so a hero could detect her. Right now, she just wanted to get off the blood that was in her dress.

''Why does mafioso blood is hard to take off? Is something that they eat?" Asked Yor to herself.

All of the people that she killed were piled up. In a few minutes the heroes and the police would be there.

Yor was not an amateur, she has been killing since she was young, so she knew what cards to play when dealing with Heroes or Pro. However she and a rule, she wouldn't kill anyone that wasnt on her hit list.

''Huh?" Said her noticing something wrong.

She saw her fighting dress got torn up a little bit.

''Oh no my dress! What I do? This is my only good dress. I can't go to Nemuri-senpai party like this.'' Said her nervous.

Despite her being an assassin she was still pretty humble and shy. She didn't like the other coworkers in UA whispering behind her, saying that its weird that she hasn't found a man yet or why she is always rejecting people. She wanted to have a boyfriend…but she is just to shy.

''I need to get the tailor and quickly.'' Said her annoyed.

She then speed up and disappear in the darkness of the night. Leaving no trace behind so someone could track her.

Later

The police and some pro heroes (Ereserhead, Manual, Mt Lady and Death Arms) arrived at the hotel and quickly went to the penthouse. The police was already there with detective Tsukauchi as the main investigator.

'Is this everyone that you all found?" Asked Ereserhead to the detective.

''Yes, there is not a single man that survive. All casualties and nobody had a pulse when we arrived.'' Said the detective very cold.

The pro heroes went off to look at the main target, Raiden. They soon found out the ´´Wreckus´´ costume and put two and two together.

''I´ve been looking for this man for 4 months and he has been turned into a pincushion.'' Said Death Arms annoyed.

''Yes, I guess someone want very happy with this operation.'' Said Mt Lady a bit cold.

The heroes saw the state of the room and it looked like a horror movies. Guts, blood and skin was around everywhere.

''Jesus, it was a massacre. It would been a miracle if someone was still alive.'' Said Manual in fear.

''What kind of person would have done that?'' Asked Death Arms.

''I don't know.'' Said Ereserhead.

''Maybe a new villain who wanted to kill the competition. I mean literally.'' Said Mt Lady.

''Looks like we have a bigger fish to catch here.'' Said Manual.

''Well the surveillance camera were all down and there was no witness. Whoever did this is a master in stealth.'' Said Tsukauchi very annoyed.

''We need to check the area. Call your man to do some investigation all around.'' Said Ereserhead.

Tsukauchi understood and sent out some officers to the streets. All of the looking for something or someone that was near this hotel.

''So any clues left?" Asked Eresehead.

''No. There was no trace of hair, sweat, skin or even a little glimpse of a DNA particle. Whoever did this was a professional.'' Said Tsukauchi nervous.

''This what we need a big monster around the city.'' Said Death Arms nervous.

''Christ, he even cut out stomach of this fellow!'' Said Manual in horror.

''I am going to be sick.'' Said Mt Lady.

In the end the officers found no clue or no lead up towards the person who did. They felt like there was someone very dangerous around the city and they need it to find out who it was.

At Yor´s apartment.

Yor lived in a small apartment. It wasn't much but she felt like home. After the job she took a bath and wanted to relax a little bit before bed. She was going to grab a bottle of water, but she messed up and let the thing falled. Normally she would be able to catch it but she was tired and she was at home.

Crack

''Oh no. Why does this always happen? When it comes to house shores all I do is mess up.'' Said Yor sad.

The next day

Yor went off to the tailor that she always went. She made sure that there was no trace of blood or organs in her dress before she turned inn to the tailor.

''Ok, I need to see if they can do this.'' Thought her.

She went inside of the tailor asked like usual.

''Excuse me!'' Said her.

''oh it's been a while Yor chan.'' Said the tailor.

''Hello there. I would like you t of ix my dress. But I can ask you to be in a hurry? I will need for tomorrow.'' Said her.

However while she was talking to the tailor someone was looking at her. It was a tall handsome man, he was blonde and had a serious look. Yor felt that he was staring at her for a while.

''Excuse me, you´ve been staring at me for a while now. Do you need something?" Asked Yor.

''Uh no! I was just thinking on how beautiful you are.'' Said the man.

Yor felt a little bit of hope, she got an idea on her head and since this man said she looked beautiful it didn't hurt to ask.

''As in my appearance left an impression on you?" Asked Yor.

''Uh well yeah…is something wrong?" Asked the man.

''Uh…'' Said Yor a bit shy but she need it this. However, before she could even talk something cute came towards them and said something that hit her like a truck.

''Papa!'' Said a little girl with pink hair.

This is the end of this chapter. Yor had her first assignment of the story and how she operates. She usually kills villains and corrupted politicians; this how operates in the main canon story as well. Also here she meet two certain someone that would become precious to her in the future. More that later.

By the way here are the quirks that I decided on the two.

Yor Briar- Weapon Radar: She can detect something that can be used as a weapon in a rage of 1 meter from her stand. She needs to see the object and concentrate to see what she is going to use. In her curriculum she puts that she has a regular radar quirk, so nobody can suspect a thing.

Llyod Forger- Quirkles. (All the agents of his base are all quirkless. This way they can pass by anything and nobody can suspect a thing).
