Victor is a trainee animal trainer at the border of the kingdom. He dreams of having a majestic monster companion, but he draws a card and draws two ancestors - twin elf siblings in human form. The younger brother is a top prodigal who spends money every day conducting explosive experiments; the elder sister is a severe social phobia and uses Victor as a shield when she encounters strangers. Everyone in the city is laughing at Victor as "the worst animal trainer in history." But the true identities of the siblings are the orphans of the Elf royal family, and their bodies contain ancient memories that can subvert the continent. As the villains chased them, the siblings' powers gradually awakened. Victor, the "unreliable" animal trainer, became the spiritual core of the siblings. The three of them went from hating each other to relying on each other for life and death, turning the entire continent upside down.
