Raised among fellow orphans at the Hyakuya Orphanage, Yuuichirou miraculously survived the iron grip of vampire rule and managed to escape. Fueled by grief and a burning desire for vengeance against those who took his loved ones, he enlisted in the Imperial Demon Army and forged a pact with the powerful Black Demon Asuramaru. Driven by an unrelenting fighting spirit, he cherishes his comrades as irreplaceable family—while a forbidden Seraph power lurking within him casts a long shadow over his fate.
