## Description
In the Phoenix Kingdom, there is a man known as the Corpse Killer.

A duke attempted to usurp the country using an imposter of his daughter. A necromancer who once warred with the Phoenix Clan lurks in the shadows.

Wilhelm, a new Knight of the Royal Guard, becomes entwined with investigations into the forces working to oppose king and country. He is assigned to the personal guard of Master Alchemist Topherf, a descendant of the Serpent Clan.

Together, they must understand the history of the Phoenix Kingdom, two immortal races, and the body of a young duchess kept suspended at the moment of her death.

Wherever the pair go, a deep fate awaits them...
