Ken died during the time wars of 3421, betrayed by his best friend and lover. However, the goddess took his soul and gave him the opportunity to choose a talent.
Ken chose the ability of the time-cutting sword, which allowed him to cut time and speed up or slow down the area where he cut. He also chose the space-cutting sword skill, which allows him to cut the air and open a space rift wherever he wants, and the other feature of those rifts is that if he cuts the enemy while the rift is opening, it will deal a lot of damage.
Ken combined his time and space cutting sword abilities and gained the time and space cutting sword ability. Thanks to this ability, he will be able to cut the air and create a rift in space, causing a time hurricane, and travel through time when he becomes stronger in the future.
After choosing his abilities, Ken made a soul contract: if he does not die after 80 years, his future self will be able to travel through time and learn about future and future events, but if he does not comply with the contract, his soul will be burned.
Ken also chose the mind transfer ability, allowing him to send whatever parts of the mind he wanted to another mind.
The Goddess gave Ken a task: "There is a Demon Lord in the world I will send you to. Your mission is to defeat him. Then you are free to do whatever you want."
Ken was born into a powerful warrior family in his world, and this family was one of the most famous and powerful warrior families in that city.
The Goddess teaches Ken how to create a magic circle, telling him to absorb the mana around him and gather it around his heart to form a circle. Ken easily learns this ability and moved things around with ease.
At the age of 5, Ken continued to develop and increase his magic circle and became the 4th circle magician. His father asked, "Are you ready for today's training?" and Ken said, "Yes, I am, Dad."
In his family, it was customary to teach him swordsmanship and sword arts by the age of 5, and Ken mastered these skills within a week. Secretly from his family, he also took up magical swordsmanship.
While Ken honed his sword arts and magical swordsmanship, he also learned to use his mind transfer ability. In this way, he would be able to pass on his memories to others.
