Born into a loving family, Femicia appears to have a bright future ahead of her. When she finally turns five, the time comes to go to the church to have her skills appraised. However, while she does receive a monster tamer skill, it turns out that Femicia has zero stars for that ability. To make matters worse, society considers those who have zero stars to be harbingers of misfortune; as a result, Femicia is shunned by everyone—including her family.

Soon enough, Femicia is chased out of her village and is constantly on the run. Fearing for her life, she decides to masquerade as a boy and change her name to Ivy. With a goal given to her by a fortune teller to reach the royal capital, Ivy meets and successfully tames a slime, starting an unlikely friendship that may provide a means to get the destiny she deserves.
