"While he was on his way to the boss, he saw a material dealer selling old items on the road and saw the ring of the strongest hunter among them. He bargained with the seller and after half an hour they reached an agreement.
By transferring her ki to the ring, Nijin made the ring her own item and ensured that no one else could use it. The ring started to shine and turned golden.
Its feature is to increase its strength fivefold, but only as long as the ring is on the finger. It will be enough to defeat the boss.
The Boss did not sit idle either. He grew stronger and said: 'I have waited all this time for you to come, but in order to reach me you must defeat my students.
His best swordsman student comes and says: 'I have worked all my life to defeat you. This is the meaning of my life. If I defeat you, I will gain absolute power and become the strongest.
The swords begin to clash, and after clashing many times, the opponent's sword breaks. Nijin also sticks his sword into the ground and starts fighting fist to fist.
After a while, both sides got tired and gathered all their strength to punch. The opponent collapses to the ground and Nijin is standing.
"Boss comes and says: 'I trained you to beat him, not to beat him.' It casts a very powerful spell and hits the opponent.
His student said: 'I'm so sorry I couldn't beat you. 'I disappointed you.' It turns to dust and the expected moment comes. Nijin, the strongest man in the world, and Bossu, the strongest monster in the world, and the fight begins.
Nijin takes out the sword she stuck in the ground and Boss takes the sword out of its sheath. The swords collide and the Boss's sword has become very large and heavy.
Nijin and Boss were ready to use their powers against each other. Nijin attacked with his remaining shadow power, but the Boss's defenses were too tight.
He only has a little shadow power left that he added to his sword. He saves it for one last blow. It has been a long fight and both sides are covered in wounds.
Nijin hits him with his remaining shadow power and the Boss falls to the ground. Meanwhile, Nijin vomits blood and her internal organs are badly damaged. However, the ring Niji received in exchange for healing will not be able to be used again.
He uses the ring and heals all the wounds, but the ring shatters and turns into ashes. As he went to the Boss, he said, 'Don't do it! If he kills me, my boss will come to this world. He is hundreds, even thousands of times stronger than me.' he says.
'He won't come as long as I live.' said. 'Let's be friends.' Nijin understands the situation and says, 'Let's be friends then.' he says. Joining forces, 'We will defeat your old boss.' they say.
They work to become stronger and they work to restore the world. Since the war is over, monsters and humans become friends and live together. Meanwhile, Boss asks: 'What was your name?' 'My name is Det.' he says. 'We have a very strong opponent.' And they set out to get stronger."
