Days before the city levitstar, just after the mission of the party where there were sixteen.
After leaving the party on the orders of his superiors, Aron trained and improved his skills to face ten again.
In one of his missions, he was now able to better control his ability, being able to throw his chainsaw blades outside his body.
He can now also put chainsaws anywhere on his body. At one point, he found out about the city and that it had a kōki, so he decided not to follow orders and go on his own.
To move faster, he cut his feet a little to create mini chainsaw blades to use as skates, allowing him to move faster.
When he arrived in Levitstar a few days before the auction, he walked around the city seeing many things, but he also saw the mercenaries.
He followed them closely, observing them, until night fell and the infiltration began. At this point, Aron was already inside waiting, and Ocho and Vell left the auction room.
"To be honest, I was bored of waiting around in there. Just watching made me sleepy," said Ocho.
"Yes, of course, I was tired of being inside too," she said timidly.
In the hallways, they see a boy. This is Aron, who was waiting for Ten, but he's not there. Aron watches them.
"Hmph... Ten isn't with you. I was waiting for him," said Aron.
"No, and who are you? An enemy we have to kill?" replied Eight.
"Let's just say I want a rematch," said Aron.
The atmosphere immediately became tense. Aron advances, the girls get into position, but from behind, someone hits Aron, sending him flying.
He crashes into a wall. The one who did this was the man standing in front of them. The girls look at him in surprise, so they get back into position.
"Wow, it seems you're not afraid despite seeing that. I'm surprised by your ability," said the man, smiling.
"We're not novices. Why would we be afraid of you? We'll kill you easily," said Eight.
They launch their attack, but out of nowhere, the man disappears and a fist appears out of nowhere in front of Vell, hitting her and crashing her into the wall.
Eight activates her ability. She thinks this is the end, but the guy who was a few meters away is now suddenly in front of her.
She receives a kick to the abdomen, sending her crashing into a wall. The man approaches Vell, kicks her in the face, leaving her broken and bloody.
Eight sees a little of what happened to Vell, gets up again, but the man punches her in the stomach, making her spit blood.
Then the man punches her in the face, destroying it and leaving her unconscious in a pool of blood. The man leaves, and at that moment, Ten arrives and sees the scene.
Aron, who is unconscious from the blow, suddenly gets up and sees the scene and Ten standing there. He remembers the man.
"Hey, you have to be careful, there's a dangerous guy here!" Aron shouted.
"Did you do this?" asked Ten.
Aron is confused by what he says, when a voice appears, belonging to that man, who has returned.
"It wasn't me, don't worry, it wasn't that difficult to deal with them," said the man.
Now in the present, Ten is surprised to see that man, standing there as if nothing had happened, doing nothing.
"You did this, but who the hell are you?" said Ten angrily.
"Wow, you say that without even introducing yourself first. How rude," said the man.
"Damn it, you're mocking me!" shouted Ten, running towards him.
"Hey, wait, that guy is stronger than you think!" Aron shouted, running after him.
Just then, the man took a step, disappeared into thin air, and a fist appeared in front of Diez's face. He didn't have time to dodge and ended up getting punched in the face.
Ten flew through the air and crashed into a wall. Aron, who saw this, was ready to counterattack, but before he could, the man appeared in front of him.
He punched him in the stomach, sending him flying. Aron crashed into a wall, breaking through several others along the way.
In the rubble, Aron is already unconscious, Ten gets up from the ground, without thinking twice, he goes on the attack, pulling out his hidden blade leaves.
He attacks, but the man dodges without any problem, kicking Ten in the abdomen, followed by a punch to the face, leaving him on the ground.
Ten is still somewhat conscious, not knowing what is happening, but it is as if the man knows when they are going to attack. However, he thinks better of it.
"How could he know which direction we were going to strike? It doesn't make sense. Can he detect us?" Ten thinks.
The man approaches him, looks at him for a moment, then smiles at Ten's situation.
"Perhaps you're wondering what my ability is, right? Don't worry, you'll find out soon enough," said the man.
"So what, you want to kill me once and for all?" said Ten.
"Well, I would, but I won't. You know why? I'll tell you a secret, even though it's not really a secret. I'll just let you live so you can know this," said the man.
"What do you mean? Don't you care about your personal life?" said Ten.
"I didn't mean that. I'm just saying that you should keep this in mind," said the man.
"What the hell do you mean, don't forget?" asked Ten.
"Well, you should know something about me. My name is Safario Seba, but everyone else calls me Black Sheep," replied Safario.
This left Ten even more confused, as he had never heard the name Black Sheep before.
"Who the hell is that, Black Sheep? Who's called that?" said Ten, on the verge of losing consciousness.
"Let's just say it's something they gave me, so good night, Kanz Shaw," said Safario, leaving the place.
"How the hell does he know my real name, who is that guy Devils... my vision is very blurry, my body can't take it anymore..." said Ten, losing consciousness at the last second.
Meanwhile, elsewhere, Five continued to chase the girl, who kept running until she entered an alley.
Five lost sight of her, entered the alley, and inspected the place, but suddenly the blade of a katana appeared.
Five dodged the attack, which almost cut his face. It was the girl who had attacked him.
"Hey, why are you following me?" asked the girl.
"I just suspect you know something, don't you?" replied Five.
The two stared at each other, both drawing their katanas, the girl from her katana sheath, while Five from his umbrella sheath.
Without warning, the two attacked each other, their katanas clashing together. The girl crouched down into position.
She attacked from below, trying to cut Five down. Five dodged the attack, but something happened to him. He had the feeling that he couldn't let himself be cut by that katana for anything in the world.
"Hey, that katana seems a little strange to me. What makes it so dangerous?" said Five.
"Well, you'll find out soon enough when you die," said the girl.
She attacks again, Five dodges the attack and distances himself; he has to analyze her attack pattern.
"This is going to be dangerous, but hey, top mercenaries are known for being the most dangerous, so it's no joke," said Five, charging at her.
A clash of swords is heard, each trying to kill their opponent.
Meanwhile, Two and Four are walking outside, being pursued in the distance. They separate, each going their own way, while being followed.
