Arcaniel experienced the saddest day of his life.
The grandfather who had raised him passed away, and soon after, he heard the news that his parents had also died.
To continue living, he was forced to use the Grimoire of Life — the legacy of the Life Sage, the controller of life — the final gift from his parents.
Ironically, this treasure is still sought after by greedy people, which means Arcaniel must not be careless or his life will be lost.
