The System's Alpha: Taming My Beast Mates

Isekai power fantasy blending snack diplomacy, mecha warfare, and harem bonds.

Pro-gamer Sylvester lands in the Iron Tribe as a reviled, heavy outcast destined for early death. A Beastgirl Favorability System activates, letting him forge contracts with three beastgirls using modern junk food as diplomatic currency. Their affection fuels his physical transformation into a commanding Alpha. When rival heir Julian corners him, Sylvester answers with firearms, vodka, tanks, and close-in weapon systems, crushing the ambush. Exiled to the wasteland, he converts scrap into a steel fortress, shatters Julian's cavalry, and claims the throne at the head of a mechanized legion and his devoted beastgirl companions.
