In a society composed of people with animal characteristics, Belle Lablac stands out as the only individual possessing no animal features whatsoever. Driven by curiosity about her origins, Belle departs from her hometown and travels to the city of Schubertland to receive the status of Nomad from the city's ruler, King Rawhide. During this journey, she is trained by the legendary swordsman Sian Lablac. Unfortunately for Belle, due to a complication, she is unable to injure others with her legendary sword, Runding. Her only remaining option to defeat opponents in battle is to break their swords, an act that is heavily frowned upon. Although she is ostracized for her appearance and hated for her disregard of societal norms, Belle remains resolute as she embarks on a perilous journey to find her rightful place in the world.
