Goulart Knights: Evoked the Beginning Black

Humanity relies on the Goulart Knights, fighters able to manifest their spiritual power as Holy Grails, against creatures known as Archons. Investigating a devastated settlement, a group of knights finds a surviving girl, Spika, and her dog, and takes them back to safety.

Nil tries to reach the traumatized child, but her unlikely survival arouses suspicion among the authorities. As another threat approaches, the knights must decide whether the girl is someone to protect or someone to fear, and whether their assumptions have blinded them to the danger nearby.
