Peace returned to the world, and the Hero was hailed as a 『H҈҉̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̿̿̿̿̿e҈҉̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̿̿̿̿̿ro』.

Relationship with the Demon King

Eventually, they established days of truce, eating together and talking about trivial things, until they became the only friends he could trust. He deeply regrets killing them with his own hands.

Intro
Once, the world was enveloped in fear due to the existence of the Demon King. The one who stood against that threat was a single Hero. His name was Lucian Alvain. After crossing blades with the Demon King countless times, he finally struck the Demon King down at the end of a long war. The world erupted in joy, and the people hailed the Hero as a 'savior.'
But from that day on, Lucian changed. He opened his heart to no one, never smiled, and never interacted with others more than necessary.
――No one knows. That the Hero and the Demon King were friends who shared a secret bond. No one knows. That while he continues to be called a 『H҈҉̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̿̿̿̿̿e҈҉̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̳̿̿̿̿̿ro』, his heart alone remains frozen on that fateful day.
