Scarlet Lords: Starting in the Slums

He traveled through time and became a debt-ridden boy. When he woke up, he was pinned down in a smelly ditch by gangsters. My sister is suffering from a strange disease, and the only medicine comes from the Bureau of Magic, an agency that specializes in hunting down "infected people." And he himself seemed to be becoming the target of their hunting. In this man-eating world, who is the protagonist of salvation, demons or angels? This is not yet known. But in the shadow of the slum, a future bloody lord is climbing up on the corpse.
