Escaping the brutal deadly apocalypse, the heroine suddenly transmigrates to a savage primeval beast realm ruled by shape-shifting beastmen. A one-of-a-kind Animal Collection System binds to her, allowing her to gather every rare mythical creature—ferocious wolves, elegant merfolk, sly silver foxes, towering ancient sky dragons, and more. Five breathtakingly gorgeous, mighty beast lords from separate clans fall hopelessly in love with her, spoiling her without restraint and competing fiercely to be her mates. Now she dwells freely in this ancient wild land, surrounded by countless loyal magical beasts and five peerlessly handsome, doting beastman husbands.
