For as long as he can remember, Kaito Kurogane lived a quiet life tending to the ancient shrine his late mother left behind.
It was a peaceful existence - until the day he and a college student named Naofumi Iwatani discovered a strange book deep within the library's archives.
A book that spoke of four heroes destined to save another world.
A book that whispered to something buried within Kaito's soul.
Now, torn from his home and thrust into a kingdom on the brink of ruin, Kaito must learn what it means to fight - not only for survival, but for the truth behind the blood that runs in his veins.
Because when darkness rises, so too does the shadow that walks beside the Shield Hero.
