Eliza wakes up to find she has transmigrated into a world where beasts are summoned and tamed, but shockingly, she has turned into a low-rank chicken. Despite her status as an S-rank genius student, this summons is considered humiliating. A system detects her ancient phoenix bloodline and offers to activate an evolution process through bonding. Though Eliza initially refuses to bond with what she sees as a worthless beast, the system warns that without bonding, she will face backlash. After discovering her chicken form has SSS-rank potential yet was abandoned, she reluctantly agrees to form a bond, setting the stage for her transformation.
