'Astral Border' launched as a new generation VRMMO. Reito Kanzaki, who applied to be a test player and was selected, was informed by the guide AI that he could not log out until he cleared the game.

Reito gathered companions who shared his goal, raised his level to the theoretical maximum, and defeated the final boss, the Demon God. However, his three companions lost their lives in the battle.

Reito thought, "There's no meaning in clearing it without my companions," and he was sure he had used a skill that revived his companions at the cost of his own life. But for some reason, he woke up in reality.

"I... logged out?"

Three years spent in the VRMMO had passed as merely three days in reality. Woken up by a sister whose existence he couldn't recall, Reito felt a sense of unease, realizing something was different from the reality he knew. Then, on his way to school for the first time in a long while, he encountered a scene where monsters appeared in the town. Unable to ignore people being attacked by monsters, Reito stepped in to help, and thus noticed the anomaly.

"I can use skills... in reality...?"

The skill Reito used seemed rudimentary to him, but it didn't appear that way to those around him. Classes on handling skills were held at school, and there were practical training sessions in dungeons. Reito gradually came to understand.

That his abilities, as one who held the title of Demon God Slayer, were extraordinary even in this reality.
