Humans were expelled by the demons to the islands in the south of the mainland and survived for 1,500 years.
Until the "Holy Sword" was born.
It is a living weapon that uses flesh and blood as soil, magic power as nourishment, and hatches from the user's body.
Under the powerful power of the Holy Sword, the human expedition led by a brave man once again launched an attack on the demons, and humans finally set foot on the land that originally belonged to them.
Kane Barnes is a clerk in the logistics department of the Restoration Church, but he doesn't want to stay in the safe rear. He wants to go to the battlefield, kill demons, and avenge his family members who died twelve years ago.
To this end, he participated in forty-eight holy sword adaptation tests, but also received forty-eight "unqualified" results.
But little did he know that something had long been parasitized in his left arm.
When Rust Island was captured by the demons and the "Swordless Saint" fled to him with a holy sword embryo, he smelled an opportunity.
In order to gain strength and fulfill his own obsession, he resolutely took on the task of protecting the Saint.
At this point, the gears of fate began to turn.
Let's wipe out all the "demons" that endanger "humanity"!
There is no possibility of reconciliation and coexistence, only one party can be completely slaughtered, like a parasite and a host.
Either the host kills the parasite, or the parasite eats the host clean.
The story of the survival of the evil race begins here!
