On the small Japanese island of Tokunoshima, 18-year-old Nao Suzuna has dedicated herself to Japanese bullfighting, or "togyu." Every day, she cares for and trains her beloved Chibi Bull. Suzuna was shy from a young age, but her life changed when her father agreed to let her have her own bull. She immersed herself in "togyu," learning about responsibility and the rewards of hard work. Now, in the final months of high school, she's aiming to clinch the island-wide championship. And she has another dream - becoming a hairstylist like her aunt. But to get trained, she must leave her home, and Chibi Bull.
