In his previous life, Bran — a beastman of the wolf clan — was mocked for being unable to shift, fell into drinking, and let his wife and daughter freeze to death in the bitter winter, dying himself in endless regret. After being reborn, he unexpectedly awakens the power to form pacts with all beasts. Using that gift, Bran hunts and gathers herbs in the forest, and not only pays off his debts and improves his family's life, but also unselfishly leads his clansmen to prosper together. Faced with the provocations and schemes of poachers, greedy merchants, and selfish relatives, he repeatedly turns danger into safety with the aid of the beasts. When the forest faces a fight for survival against arson set by human hands, he gathers the power of all beasts to summon a torrential rain and extinguish the blaze — and at last becomes the true "King of the Wild," guardian of both his tribe and the forest.
