My Dying Snake Is an SSS-Rank Dragon

Betrayed by the golden phoenix she raised for ten years, Elara is reborn on the day she must choose her bonded beast. She stuns everyone by rejecting the S-rank phoenix and claiming a dying F-rank black snake. Mocked as a freak, she discovers her "birthmark" is a magic seal—and her worthless snake is actually an SSS-rank Abyssal Dragon. As the phoenix regrets too late, can Elara and her dragon rewrite fate itself?
