One month away from her birthday, Unue's time to find a task is running out. Scrambling to find anything worthy, she catches wind of reports of wild beasts attacking other villages, with even some of the townsfolk disappearing when the creatures retreat. Convinced this is how she can earn her name, Unue sets out to track the beasts down and save the kidnapped people alongside her best friend. But there is more to these mysterious animals, secrets that threaten to upend everything she knows about her world.
