The Sin of Greed

All for One, the Demon Lord of Greed, captures his rebellious son Izuku and conducts a ritual to destroy that blasted sword One for All. He accidentally summons Yoichi, a human who looks exactly like his deceased younger brother. Yoichi's isekai dream rapidly turns into a nightmare as he realizes this world's Hisashi has no intention of letting him return home. (Updates Tuesdays.)
