a teenaged girl who lost her memories, and nearly her life, before the ancient and troublesome parasite Samson bonded with her. He replaces her hair, and looks like long dark hair. He has a mouth and eyes on the back of her head, and he can shape himself into various things, expand, or harder to form drills, spikes, his own body, or even wings to glide with. He also increases her physical power. He has agreed to support her in any choice she makes. She is kind, and generally nice.
