Beastward Academy: Reborn, I Claimed My Sister’s SerpentEpisode 28

Elaine Tidesong spent ten years feeding and bleeding for the proud noble dragon. She wishfully believed they would bond on the day he took human form. Yet he chose her sister instead. Together, they cruelly murdered Elaine and burned all her loved ones to ashes. Reborn to the very start of her fate, Elaine turns her back on the dragon and takes in a frail feathered serpent named Nyxen as her familiar. The weak-looking serpent hides terrifying power. This time, Elaine will no longer be drained by the dragon or her sister, and she will protect everyone she loves from their evil claws.
