A demon-slayer bound by destiny fights a curse that spans centuries. The gods themselves stake their power on whether one man can break a bloodline's suffering. Kabuto isn't chosen because he's special, he's chosen because his family bleeds, and something has to stop the bleeding.
Kabuto stands alone against darkness that has hunted his bloodline for centuries. When Kuroyasya Douki, a demon lord imprisoned in the depths of hell, claws his way back to the mortal world, he brings with him an ancient vendetta against Kabuto's entire family. The Black Night Demon wields sorcery and steel with merciless precision, leaving no one safe from his reach. Kabuto cannot fight this battle alone. The divine spirits of the North, West, East, and South take notice of his struggle and lend their power to aid him. Yet his greatest weapon comes from an unexpected source: a talking sword forged by his own father, a blade with a mind of its own and motives that remain unclear. Between trusting the gods above and relying on an unpredictable weapon, Kabuto must find the strength to survive long enough to protect his future. This is a tale of duty, destiny, and demons, where one man's resolve determines whether his family line will continue or perish in shadow.
