Worthless incarnation

Ashborn is a common trainee who is bored in a society where ability and power are paramount.
After escaping the destruction of his fatherland's heretical city by chance.

He endures for many years without having any special abilities or talents and manages to survive despite all kinds of difficulties. However, he ultimately perishes in agony.

But just before he passes away, he accidentally acquires the "Blade of regression," which allows him to go back in time and start over.

Even after regression, he continues to experience agony and manages to get by without anything.

But something had changed, his best friends were still alive, and he was stronger than he had ever been, but he was unable to save the heresy city.

He decided to go back to the past again after realizing that he manages to save at least his closest friends, but this time, instead of going back, he was sent to a tower of hope.

He would receive an artifact that could transport him back 10 years before Heresy City was destroyed once more if he could reach the highest level and kill the individuals he was ordered to kill.

"I'm going to have a better life than my former one no matter what, and even if I have to fight for it, I'm going to kill anyone who is in my way."
