Beacon was in a state of excitement of new professer.

The topic everywhere was about him, and RWBY, JNPR were also talking about him in the cafeteria.

Yang: So...Professor Sung Jin-woo, what do you all think?

Blake answered as he ate grilled fish.

Blake: Well...He's very mysterious.

Jaune also said, thinking about the shadow soldiers shown by Sung Jin-woo.

Jaune: Yeah, really…It was so mysterious that it was scary...

Weiss interrupted.

Weiss: Professor? He's almost crazy!

Yang: Because that shadow knight grabbed your head and threw it away?

Weiss: It almost killed me!

Yang said as if to calm down.

Yang: Wow. Calm down Ice Queen, he's getting to know us gradually. If he's a danger to us, he'll have killed us earlier

She joked at Weiss.

Ruby: I think he's awesome, his shadow soldiers and even weapons!

Are their weapons made of shadows, too?

Ruby kept muttering.

Nora was also telling Ren what she had done with Sung Jin-woo.

And Phyrra opened her mouth.

Phyrra: It was definitely different

The other seven teenagers looked at Phyrra.

Phyrra: The power of the man...What on earth was it?

What exactly was that?

Others thought about Sung Jin-woo again.

Multiple shadow soldiers, the combat skills that Ozpin mentioned, teleportation, etc., although he didn't see them in person

Everyone thinks he has a huge secret.

Meanwhile, Sung Jin-woo was walking to the professor's table with a tray in his hand.

There I found an older-looking professor, with a rather striking white moustache and his hair neatly arranged in the middle. Also, he was wearing a reddish-brown suit.

Oh yeah, you're the new professor.

Sung Jin-woo: Nice to meet you.

Peter: I'm Peter Port, a veteran hunter here and one of Beacon's faculty.

Sung Jin-woo: Sung Jin-woo, feel free to call me Jin-woo, and what do you teach?

Peter: I study and teach about grimm

Jinwoo swallowed the food and said.

Sung Jin-woo: I'll go to the your lab later

Peter: Oh, really?

Sung jin woo: Yeah I guess

Peter replied with a smile.

Peter: I'll come and see you anytime

Sung Jin-woo stood up from his seat and said he would go first, then left the cafeteria, and as he was walking in the hallway, and his scroll rang.

It was some kind of cellphone thing Ozpin gave him when he first arrived at Remnant.

Jinwoo quickly arrived at the top floor office where Ozpin was located using a shadow exchange.

Ozpin spoke bluntly.

Ozpin: There's an elevator

Sung Jin-woo: It's still comfortable.

So why did you call me?

Glinda showed me a tablet, and Ozpin began to explain.

Ozpin: A few days before the start of the new semester, we heard that a man named Roman Torchwick was stealing dust from a dust shop, so it seems like a new criminal organization or something is being with White fang.

Sung Jin-woo: So what?

Ozpin: I want you to know something about this case, we have an undercover agent named Qrow Brenwen, but he has chosen you for a different mission at the moment.

Sung Jin-woo: That's great, I was going to go out on the vale later anyway, but I also wanted to do a preliminary survey...Let's do that.

Ozpin: Thank you

Sung Jin-woo turned back and headed for the elevator.

Professor Ozpin. What is certain is that he was hiding something. Over and over again.

Jinwoo decided to solve this idea later because it was not urgent, and now it was his second class.

This time it was his turn

in a few minutes

All the students fell to the floor.

Jinwoo just dealt with the students by applying his skills to fight with two daggers

From the students' point of view, it just looked like a monster.

The students were simply monsters themselves, with their ability to summon weapons suddenly, their bodies becoming transparent when they were not chameleon Fionus, their speed exceeding that of Semblance, their enormous dagger skills, and their psychotropic powers exceeding those of Phyrra's magnetic force or Glynda's psychotropic force.

They collapsed under Jinwoo's overwhelming power, and some even fainted.

Yang of Team RWBY, who ended his fight with Sung Jin-woo, asked him a question.

Yang: Who the hell are you?

Sung Jin-woo: Me? Just a teacher.

In the meantime, Ruby was asking to show Jinwoo's dagger.

And Weiss and John were down on the floor, struggling, Len and Nora were sitting and resting, and Blake and Pyrrha were drinking water that Jinwoo had given them.

As they kept asking questions, he started to get a little bothered, but it was not a bad feeling because it had been a long time since he had this atmosphere.

So Sung Jin-woo said one word with a slight smile.

Sung Jin-woo: Shadow monarch.

Ruby and her friends gave up trying to understand what that meant, and Jinwoo said class was over and told them to have a good weekend before leaving.

That night, a group of white puffins were retaking the ship carrying the dust.

White fang solider 1: Now, let's get out of here before the police come

Then a soldier noticed a strange sensation.

White fang solider 2: I...Albert, somethings wrong.

Then a one of the soldier found a man

The person was wearing a long black coat, and the eye area was glowing purple.

White fang solider:Who are you!

He didn't answer.

Then, as soon as a soldier put his eyes on him to push him, the dagger, who did not know where the man came from, cut the soldier's throat.

The man spoke in a tremendously heavy voice that they had never heard of.

And the man's identity was Sung Jin-woo.

Sung Jin-woo: One

The White fang soldiers pointed their guns at Jinwoo, but Jinwoo blocked the bullets coming at him with a dagger and cut off the tendons of the White fang soldiers' legs and arms.

They were in pain, and Jinwoo spoke in a cold voice.

Sung Jin-woo: I want you to live.

Prince Whitefang 1: On the right foot...Who the hell are you?

Sung Jin-woo: Me? Just an ordinary Beacon teacher

And he turned around and tried to get back to the beacon.

And he planted the soldiers with the shadow of the High-oaks and the shadow of the ants and ordered them to do so.

Sung Jin-woo: Kill them if they don't turn themselves in until midnight (though I don't know how long the patience of High-oak and Ant Shadow will last)

Then he disappeared.

And the next day, some white snail injuries and deaths were reported. (Also, the story of embroidery)
