During the Taisho period of 1918, seventeen‑year‑old Benio Hanamura defies convention with gusto. A spirited and feisty tomboy, she pursues kendo and daring tree‑climbing escapades alongside her closest companions Tamaki and Ranmaru. Determined to secure love on her own terms, Benio faces familial expectations and, amid war as the nation trembles, confronts trials of affection, autonomy, and camaraderie in the shadows of conflict.
