After killing Divalo, the God of the Void, Ken returns home to Earth, but cannot find the Earth and other planets in place. Ken looks into the past. Before Ken went to kill Divalo, he took out Divalo's anger towards Zeus on the planets. Since the Earth was destroyed, his family also died.
In his anger, Ken erases and destroys the future and past of the entire universe in which he lives. He sees a last universe that is similar to his own but not at all and he is surprised. He thinks that all universes are destroyed in the universe wars. He goes to that universe and decides to go to the end of time in that universe. He easily cuts through space and time with his hand, he travels in time and goes to the end of time in that universe.
Ken sees someone who is experiencing similar events that happened to him, who destroyed everything in his universe and created a new planet for himself. The planet is empty, there is only 1 house, and he sees a person named Nijin sitting on the roof.
Ken encounters the last God at the end of the world in the last universe. He is very surprised when he sees another God in the Nijin universe. He thinks that he has destroyed everyone and all the Gods and takes his sword by destroying the void. Ken also easily breaks time and space and takes out his sword.
Ken tries to predict the future, but it didn't work on Nijin. When their swords collided, the entire universe shook, and every time the swords collided, the universe slowly began to disappear.
After billions of years of war, they realize that they cannot defeat each other and they draw. Nijin creates a bar next to his house and has a drinking contest. They draw again and become close friends. They destroy this universe and create a new universe together, and they become the people at the top of that universe.
