Recap of the first seven episodes of 91 Days series.

Ten years after the Holy War in Hong Kong, Mochizuki Jirou, aka the Silver Blade, and the lone hero who fought and defeated the Kowloon Children despite the loss of his lover, returns to Japan with his young brother, Mochizuki Kotarou. The two quickly discover that the Kowloon Children who survived the Holy War are seeking to infiltrate the "Special Zone", a thriving city protected by an invisible barrier that will not allow Kowloon Children entrance, unless they're invited. Red Bloods refers to the humans; Black Bloods are the vampires, and the Mochizuki Brothers are Old Blood, the last descendants of an elite clan of vampires. When Kotarou is abducted by one of the Kowloon Children, Jirou has no choice but to fight once more.

Monsters known as "Horrors" have invaded the world, entering through gates from the Makai Realm of Darkness. These corrupt, demonic creatures have the ability to seize human bodies and feed on their souls. Citizens who are out past sunset will likely never see the sun rise again, but those who live in the capital city have no need to worry—they are protected by a spiritual force field created by the sorcerer group Onmyouji. In possession of legendary armor, the Golden Knight Raikou proclaims that he will protect everyone from the Horrors. Accompanied by his attendant Kintoki and the mysterious Makai Alchemist Seimei, he strives to become a formidable Makai Knight, but Raikou is ill-prepared to handle the side effects of the armor. Disappointed by his own shortcomings, he sets out on a journey of self-discovery to master his weaknesses and prove his worth. [Written by MAL Rewrite]
