Ken from the future appeared out of nowhere and took normal Ken and Moriko with him. He took them to his future.
Future Ken had an enemy he couldn't defeat and he needed allies.
When he looked around, the world was completely destroyed. The sky turned blood red. There was no sun or moon. While Ken was wondering what had happened in this future, future Ken showed him his enemy.
Enemies were coming into this world every second. They were invading aliens from another planet. Future Ken is filled with anger when he sees them. He had lost too many of his relatives and made very powerful attacks one after another. He attacked the alien ship the aliens were in and the ship exploded. However, only the pilot was inside.
The aliens hid behind the buildings and set up an ambush. They surrounded Ken from the future and attacked him. Ken killed half of them using the Shadow Sword.
Ken from the future told about Boros. Boros was the leader of the aliens and a very powerful alien. Years ago, Boros came to invade the world. However, there were powerful wizards in the world at that time and Boros was defeated.
In the present, the battle between Boros and Ken was quite fierce. Both sides were very powerful wizards and their fight lasted a long time.
Boros made very powerful attacks against Ken's shadow summons from the future. However, Ken was able to parry his attacks and began to reduce Boros' powers using his Shadow Sword and Space Slicing Sword technique.
While Ken from the future was reducing Boros's forces, Ken from the past was fighting against Boros's soldiers. Past Ken began killing Boros' soldiers one by one using his space-cutting sword technique.
Although Boros tried to resist Ken's shadow summons from the future, his powers were gradually decreasing and Ken was beginning to defeat him.
In desperation, Boros continued to resist Ken's shadow summons from the future. However, Ken continued to surpass his powers and Boros's attacks were becoming weaker.
Future Ken tried everything to stop Boros. Boros continued to resist Ken's shadow summons from the future, but Ken continued to surpass his powers.
In the end, Boros was defeated by Future Ken. After Boros' death, Past Ken decided to leave the future world. He took Normal Ken and Moriko back to the past with him and left them in their own time.
Before returning to his own time, Ken from the future showed Normal Ken that the future had changed, thanks to his mind transfer ability.
And he gave information about the apocalyptic monster. Normal Ken realized how dark the future was thanks to future Ken's mind transfer ability, and realized that the only thing future Ken could do was return to his own time and try to change the future.
Ken from the future returned to his own time, and Normal Ken and Moriko also returned to their own time. However, Normal Ken now knew that the future could be changed and he would try to change the future.
