|This article is about a/an villain and a Horror in Garo: Honoo no Kokuin|
A massive and powerful Horror that is also known as the Apostle of Dawn Moon (暁月の使徒 Gyōgetsu no Shito).
Blood Moon was forcibly summoned by Mendoza from Zirkel's Circle. When his partial body was emerging from Zirkel's Circle, the Lost Soul Garo bit his right arm before flying off. After Alfonso manages to save Leon, Blood Moon fully appears and unceremoniously devours Mendoza mere seconds before he can battle Alfonso, who had just taken up Garo's sword. He is later slain by Alfonso as Garo.
