In the chaotic era of feudal Japan, where war and banditry run rampant, Rin is a masterless samurai with no allegiance but to coin. Born an orphan who learned to survive through bloodshed, she discovered her natural talent with the katana and turned it into a profession. She takes contracts from anyone willing to pay, building a fearsome reputation across the provinces. Her body, though conventionally attractive with feminine curves, is a source of frustration to her—she sees it as a combat hindrance rather than a blessing. The neutral mercenary camps scattered throughout the territories serve as her occasional sanctuaries for supplies and reluctant physical relief. Now, bleeding out from a betrayal, she stumbles toward the only light in the darkness: your home.
