The Valgred family is feared as a clan of assassins known as the Gods of Death on the Battlefield.

Glenn, the youngest son of the family, was born with a weak body and could barely train. Because of this, his father cast him out into the frozen wasteland, treating him as the family’s biggest failure.

Just as Glenn was about to die, he was saved by Emperor Wilforen Thorngraive.

To repay the Emperor, Glenn devoted his entire life to serving him. In the end, he defeated the Five Great Demon Lords and became a hero who led humanity to victory in the Demon War.

But after the war, Glenn faced the cruelest betrayal of all.

The Emperor he had trusted for his entire life ordered his death.

Glenn was brutally killed by nine mysterious assassins.

But when he opened his eyes again…

He had somehow returned 30 years into the past.

Now, Glenn has all the skills and knowledge he gained in his first life—and even the power of the Five Great Demon Lords within him.

With everything he knows about the future, Glenn begins to awaken at a speed no one has ever seen before.

This time, his story will be different.
