“It is said that the Elder Spirits kidnap children and turn them into ruthless warriors. They are possessed by demons, and their bodies are irreversibly changed by spells...” Kentaro had one task in life: to protect his Immortal mistress. He failed, but was given a second chance. A chance to protect your new family. A chance to take revenge on the traitor. In the end, in resisting the invasion of barbarians that destroys the country, one Spirit is worth more than a hundred samurai. Unfortunately, the legends are silent about the fact that Spirits remain people. And they can love and hate. Like everyone else, only much stronger.
