Exiled gamer builds a steel kingdom with beastgirl allies and heavy firepower.
Professional gamer Sylvester transmigrates into the Iron Tribe as a condemned, overweight outcast. He activates the Beastgirl Favorability System, forming contracts with three beastgirls whose devotion grows through modern snacks and technology. Their bond fuels his physical transformation into a commanding Alpha. When rival heir Julian ambushes him, Sylvester counters with firearms, vodka, tanks, and close-in weapon systems, shattering the attack. Banished to the wasteland, he constructs a steel stronghold, defeats Julian's cavalry, and ascends as supreme ruler alongside his mechanized forces and beastgirl companions.
