This new person was wearing a white suit with a black tie. He also had black surgical gloves on his hands. His right elbow was in the Boss's firm grip on his left hand. He had a gold lighter with Japanese symbols that meant Devil. This man is none other than Asta Ratsujin's father.
Asta first pulled the lighter back into his pocket while staring down the soul of the Boss with his bright red eyes.
Suddenly, the Boss felt someone had grabbed onto his head. His eyes widened in shock as he saw Asta had grabbed the back of his head with his left hand. Asta was so fast that the Boss could not even see him pulling his hand from his pocket.
"Something's Wrong!"
"I Can't Move!"
"This Body Is Not In My Control!"
"Why Am I Getting Nervous!"
"It's Not Possible!"
"Is This All Because Of This Man!"
"But How Is He Doing This!"
The Boss thought to himself while looking at Asta in his eyes. He could not even break the eye contact if he wanted to.
As the Boss finished talking to himself, Asta slowly pulled his head closer to himself and whispered in his ear in a cold, chilling voice. "Leave..."
Asta released the Boss's neck as he whispered in his ear. The Boss got jolted back as he was using every ounce of the strength he had, and when Asta released his neck, his body got jolted backward.
The Boss balanced himself and yelled at his Henchmen and the Doorman, "WHAT ARE YOU WAITING FOR KILL HIM!!"
The four Henchman and the Doorman swiftly surrounded Asta, but he was not bothered by them. He gazed at the Boss and murmured with a cold smirk, "Wrong Choice!"
The moment Asta finished talking, all the lights went back down. The entire warehouse turned pitch black again. The Boss tried to spot Asta, but this time. Asta did not have a lighter in his hand to reveal his position.
"AAAHH!!"
"AAARRGGHH!!"
"AAAAAA!!!"
"BAAAMM!!"
Screamed filled with pain echoes around the entire warehouse, and at the end, the Boss hears a very loud impact.
A few seconds later, the lights turned back on and revealed what happened in the dark. The Boss was started as he saw what had happened.
All four Henchman and the Doorman were laying on the broken table before the Boss. Their lifeless body was leaking black blood. All five of them were stabbed multiple times in their heart.
The Boss looked at Asta on the other side of the table. Asta was holding the same dagger that was used to stab his son. His gloves were covered in black blood. He had killed all five of them without even breaking a sweat. There wasn't even a single stain on his suit. The blood was only on his gloves, not even on his shoes.
Asta first gazed to his left with his cold-blooded eyes. He saw Ethan, Scott, and Logan standing at a distance from him. All three of them had no idea what was going on, but they seemed to understand Asta will be the one who was going to go out of here unharmed. They choose to stand beside him, trying to show him that they are supporting him.
Asta turned back to the Boss and said, while pointing the blood-covered dagger to him, "Show Your True Self!"
As soon as the Boss heard Asta's voice, he thought to himself. "We Have No Other Option! He Cannot Leave This Place Alive!" The Boss continued, "And Come To Think Of It, He Has A Strong Body! If I Can Take Over It, I Will Be Unstoppable!"
After talking to himself, the Boss used his hand gesture to call the teenagers who had been taken by his men earlier.
Suddenly, a black smoke surrounded all of the teenagers and the Boss. The Teenagers and the Boss opened their eyes, trying to suck all the smoke into their mouth.
As soon as they sucked the smoke, their body began to transform. Some of them grew shorter in height, some grew larger, and some grew bulkier. All of their eyes turned pure black color. There was no white in their eyes.
All of their skin color turned charcoal grey. Their body was emitting Black smoke.
Their mouths were dripping saliva onto the warehouse floor. Their tongues were out of their mouth as they observed Asta's stance from top to bottom. All of them were eager to attack Asta, but they were waiting for their leader, the Boss, to permit them.
The Boss was standing in the middle of his Demon's group. He slowly tilted his neck to the Demon on the far right side and permitted him to attack Asta.
Just as the Boss permitted a single Demon, he turned into black smoke. The Black smoke rushed towards Asta and swiftly surrounded him, but Asta was still unbothered by the Black smoke.
"Something's wrong here." The Boss spoke to himself.
The Boss looked at the other hand, Asta, and noticed something. He saw lightning cursing through from one of his fingers to another through the gloves.
