When Ken becomes the Master of Time, he takes his sword and opens a rift in time and wonders which time he will go to. He goes back to that time, but neither the war nor the world he used to live in is found.
After thinking for a while, he realizes that this is not his universe and he must go to that universe, travel through time there and take his revenge.
He starts looking for a way to go to another universe and disperses his shadow army throughout the universe. He sends them one by one to ask if there is anyone traveling in the universe, and if they find someone who is lying or looks suspicious, he says bring that person to me directly. He declares Rokuro the commander of the shadow army and gives him the command while I am away.
The Shadow Army finds one person, but they cannot bring him. Ken turns into a shadow and goes there, where he encounters abilities he's never seen before. The shadow soldier comes and says his name is Arduin
Ken is amazed by Arduin's powers. He sees that Arduin's arm has become a dragon arm and he can shoot flames from his mouth. During the battle, Ken uses the powers of time to slow Arduin's movements and protect himself with a time beam.
At the same time, he uses his space powers to create a field around the dragon and trap it. Arduin breaks the field with its flames.
Ken slows down the flame he throws with a time beam and creates his own flames with space power. As their flames collide, Ken also uses his shadow powers to deflect Arduin's attacks. During the battle, Ken breaks Arduin's arm and knocks him to the ground.
Arduin is amazed by Ken's powers and surrenders to him. Ken does not kill Arduin and releases him in order to recruit Arduin's powers into his own army.
Ken asks Arduin what way there is to travel through universes, and Arduin explains to him the existence of the universe tree. There is one universe tree in each universe, and it allows you to move to the universe you want by touching it.
Arduin says that he came to this universe before his own universe was destroyed in the universe wars and takes Ken there. Before going there, Arduin explains to Ken the existence of people guarding the universe tree.
Arduin explains that the guardians of the universe tree are a very powerful and respected group. Using the powers of the universe tree, the Guardians monitor people traveling between universes and punish those who travel illegally between universes, and take Ken there.
