One moment, Leo is a college student; the next, a silver-haired cat beastman with a four-year-old son and a tribe that wants him dead. In the Forbidden Forest, dying tiger king Silver marks him, awakening a hidden power. Four more S-class kings—a snake, wolf, eagle, and panther—claim him, while his son’s scent matches them all. Hunted by a corrupt elder and the Temple Council, this straight man in a world where men give birth must protect his son, claim five husbands, and rise as ruler.
