A legendary swordswoman both revered by some as a God and reviled by others as a Demon. She travels with a mysterious sword known as Yamato no Kuni no Kunimune. While searching for more ancient blades Musashi found herself following the stairs of a fellow sword collector's warehouse down into the basement. There she found a skeleton with dried blood pooled around its feet clutching a blade. Taking the blade for her own, she set off. However, before she knew it, it had changed her. The blade had been used by uncountable masters and had tasted blood of humans, Youkai and even creatures from the great unknown. By the end, it had been bewitched. And now, so has Musashi. While at heart she remains the same honest, brave swordswoman she now changes in battle, continually lusting for more blood.
