Garo: Crimson Moon - S01

Monsters called "Horrors" have invaded the world, coming through gates from the Makai Realm of Darkness. These corrupt, demonic creatures can seize human bodies and feed on their souls. Citizens out past sunset will likely never see the sun rise again, but those in the capital city have nothing to fear. They are protected by a spiritual force field made by the sorcerer group Onmyouji. Wielding legendary armor, the Golden Knight Raikou declares he will protect everyone from the Horrors. With his attendant Kintoki and the mysterious Makai Alchemist Seimei by his side, he strives to become a formidable Makai Knight. But Raikou is unprepared for the armor's side effects. Disappointed by his own shortcomings, he sets out on a journey of self-discovery to master his weaknesses and prove his worth.
