"I am no woman. I am a Samurai."
It was the Sengoku Era in Japan.
Ginko Tsukitsubata, a sword genius, fought in the Battle of Sekigahara. She wanted to slay as many enemies as she could and fight to the death for her belief, which she called a brilliant death. However, she survived--found herself among the corpses of her fellow warriors. The era of the battle of Samurais had ended.
Since then, she wandered across Japan to find a swordsman who was stronger than her, who could kill her. She was looking for a place to die. She fought and fought and fought...but it seemed like there was no one left who was stronger than her.
When she was in despair, she was transferred to another world!
Are goblins, ogres, dragons...stronger than her!?
