To save his dying sister, Firan was granted "The Arcane Necromancy," the source of necromancy, by the Creator God, and used it to turn his sister into an undead.

His sister, now living as an undead, said she was content as long as she was with her brother, but Firan could not forgive himself. Therefore, the siblings made a promise with the Creator God:

If they fulfill the Creator God's wish, his sister can be resurrected.

Wielding the forbidden power of a necromancer, they embark on a journey with no end in sight.

This is an adventure story of the two siblings, who seek to obtain the power of resurrection someday.
