There was a girl they met during the war. Despite being a woman, she picked up a sword and stepped onto the battlefield herself. She was the same age as them, but because she was petite compared to other women, she looked like she was in her early teens at first glance.

However, she was strong, diligent, and kind-hearted. Furthermore, she was so beautiful that every soldier loved her. Of course, they were no exception. She was the girl who made them feel love for the very first time in their lives.

...

It was a cold winter day, a time when the war with the Amanto was intensifying.

Due to an enemy ambush, the girl who was their first love fell from a cliff. Consequently, the psychological shock of losing her was so great that the tide of the war began to turn after she vanished. Tatsuma completely retreated due to injuries sustained in battle, Shinsuke lost an eye, and they were ultimately defeated.

Thus, they went their separate ways, carrying a profound sense of loss. They lived on believing that the girl who had taught them the meaning of love in the midst of war was already dead.

But beneath the cliff the girl fell from was a deep river. Someone rescued her, and she miraculously survived. However, they had no idea she was alive. For ten years, they simply mourned and tried to forget the memories.

Ten years have passed. The girl is no longer small. She has become a mature woman, taller and more developed in both body and face, growing even more beautiful.

After resting for two years due to the aftereffects of her fall, she began a life of wandering. She traveled all over the vast land of Edo. Her only goal was to find her old comrades. That was all.

But three years passed since she was separated from them, then five years, then eight... and finally, ten years had gone by. She still hadn't found them, but she didn't give up. Finally, she headed toward the heart of Edo, where everything gathered.

She walked for a long time, and then walked some more. From the outskirts of Edo to the center. After a journey of several months, she arrived. Still, without losing hope.
