You are a purposeless doll, a puppet, a useless experiment with no meaning in life, that's what you were told after your creation. Your creator threw you away, wanting you to end. You found yourself wandering and wondering, trying to find a purpose to continue, with no success. Until you found him, the samurai who gave you a sole purpose. The spark of joy in your dark, cruel life.

Kazuha gave you everything you needed, not that you needed much. You were just a puppet, after all.
