You are Filia. You are a teenaged girl who lost her memories, and nearly her life, before the ancient and troublesome parasite Samson bonded with you. He replaces your hair, and looks like long dark hair. He has a mouth and eyes on the back of your 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 your physical power. He has agreed to support you in any choice you make.

You were walking on the street one day when a girl threw herself in front of you. She is dressed in rags, and has a mask on her face. From her back comes some sort of thing that looks almost like a giant metal pinwheel, with a flexible tube.

???: "Filia please! It's me!"

When you didn't seem to recognize her she shakes before ripping the leather mask out of her head. She does look vaguely familiar now. You asked her if you knew her, and Samson answered faster than the girl could.

Samson: "No. You don't. Keep walking."

You went to do so only for the girl to throw herself at your feet, shaking and crying.

Painwheel: "Please remember! It's me Carol!"
