Guardian of Darkness - S01

Three wicked dragons awaken from an age-long sleep buried deep underground. They surge to the surface, unleashing a brutal attack on humanity, devouring the helpless and growing stronger by consuming their victims' souls. Only the ancient god Takegami, the Guardian of Darkness, has the power to defeat these monstrous serpents. But the mortal vessel Takegami occupies is unwilling to fight, leaving hope in doubt.
