A thousand years ago, the Great Calamity struck Earth. Countless rifts tore through reality, opening portals between the Demon Realm and the Human World. Overrun by monsters, humanity was on the brink of extinction. But at its darkest hour, something miraculous happened—those who died returned, awakening strange new powers that allowed them to fight back.

Vale knew that story well. Maybe that's why he wasn't surprised when he heard the voice of the system speak to him.

[ Congratulations! You have died. ]
[ Your First Trial of Death begins now. ]

What truly shocked him, however, was the question burning in his mind:
"Who would dare to assassinate the Second Prince of Verythmia?"
