Yuuki Aru Mono yori Chire

The Edo period has come to an end, leaving former samurai Haruyasu lost in a world that no longer needs warriors. Haunted by despair and longing for death, he drifts through life without purpose—until a failed assassination changes everything. When his mission goes awry, Haruyasu is spared by his target’s mysterious bodyguard, a young woman gifted with extraordinary healing powers. Captivated by her strength and grace, he finds a new reason to live: to uncover the secrets behind her power. But every life saved comes with a price… and Haruyasu must decide what he’s willing to give in return.
