Isekai Samurai

A legendary samurai from the Warring States period, known as the strongest swordsman of her time, finds herself transported to another world. Ginko, who lived for the thrill of life-or-death battles, had grown disillusioned after defeating every worthy opponent in her own world. Just as she loses hope of ever finding a true challenge again, she’s suddenly whisked away to a strange new realm—where her first sight is a mighty dragon.
