The year is 1850, amidst the steam-powered era of England. The Lancaster family served as Her Majesty’s executioners, earning the moniker "The Queen's Loyal Hounds." Laurence Lancaster, the son of the family patriarch, grew up cherished by his parents—naive and somewhat spoiled. However, his father, Batman Lancaster, and mother, Erza Windsor, were reviled as "aristocrats of evil"; due to certain circumstances, the entire Lancaster family was brutally wiped out. From that day forward, Laurence’s life was turned completely upside down.
