Boss "I was waiting for you, my eyes were on the road." Nijin said, "You don't have to wait anymore, your death has come, we are here and we will finish this job today."
Det adds, "I learned everything. You killed my mother and kidnapped me when I was a baby. I will take my revenge." Now that you know everything, I can kill you easily.
The boss says, "So you learned. Let's see who will kill me first." Nijin charges forward and takes out his sword and attacks, while the boss stands with his sword like it's nothing and executes the techniques he has learned with ease. The boss starts to have a bit of a hard time.
The boss says, "You have become stronger," and delivers a powerful blow. Nijin blocks it but gets stuck on the wall. Det starts to attack, but he easily dodges all his moves and throws a punch, but Det is stuck to the wall.
The boss asked, "Is that all you have powers?" and they use fusion. Their bodies merge and they become stronger than before. Now their powers are equal to the boss.
They both rush forward and their sword slashes destroy everything around them. The Castle couldn't stand it anymore and collapsed, and the Boss said, "This was my favorite Castle."
The boss pulls out another sword and they continue fighting. After a long time, they both get tired and the boss's right-hand man comes from another planet. "I have new news," he says and joins the battle.
The boss rests on the sidelines because he is tired and his right arm is also strong. They start to fight, but the right arm's sword is not as strong as the boss. After a while, the right man is defeated and killed. Nijin's sword eats him.
The boss gets angry and shows all his strength. The shape of his body changes and he becomes stronger many times. However, he was mortally wounded in his last battle. If they had attacked at that time, they could have won.
They rush forward and their swords clash. The boss prevails. The boss said, "Is that all?" he calls out, making Nijin and Det smile. The technique he learned from the strongest in the universe comes to his mind and uses the sword enhancement. This forces the boss to back up. The sword breaks and eats the Boss's sword.
The boss says, "Don't kill me. I'll tell you everything." Actually, I used to be a good person. Back then, before the strongest in the universe, I had another master.
He was the oldest enemy of the strongest in the universe, and he had killed him. However, he was not dead. He thought he was dead and he hid and got stronger and trained me.
He placed a seal on my brain and I lost my memory. After a long time, the seal was opened and I remembered everything. In revenge for my master, I killed the wife of the strongest man in the universe and kidnapped his child, making him his enemy.
If it weren't for you, my plans would have gone smoothly. My Master is much stronger than me and since he is also my Boss, he calls himself the "Boss of the Universe" and is stronger than the strongest in the universe. Nijin says, "Okay, I understand" and kills the Boss. They go to the most powerful person in the universe and go to tell about the events they experienced.
