The System's Alpha: Taming My Beast Mates

Pro-gamer becomes Alpha, arms beastgirls with modern weapons, builds wasteland empire.

Professional gamer Sylvester arrives in the Iron Tribe as a condemned, overweight outcast. The Beastgirl Favorability System activates, letting him forge binding contracts with three captive beastgirls by supplying them with modern snacks and vodka. Their rising devotion drives his physical transformation into a charismatic Alpha. When rival heir Julian forces a confrontation, Sylvester answers with firearms, tanks, and close-in weapon systems, crushing the tribal opposition. Exiled to the wasteland, he constructs a steel stronghold, defeats Julian's cavalry, and establishes supremacy with a mechanized army and his beastgirl companions at his side.
