My S Rank Beast Mate

I reborn the day I picked my beast mate, right after my jealous sister Lyra snatched the B-rank snake Voss I once married in my past life. She framed me to be exiled into deadly wilds, but I saved a wounded white lion no clan dared accept. Everyone mocks him rankless trash, until I bear two S-rank lion cubs. The priest uncovers his hidden S-rank blood, brands me the reborn Sacred Daughter. Lyra's fake saint dream crumbles with weak snake cubs, yet she screams I stole her glory. Who will pay for all her bloody betrayals?
