Filia Medici was once a somewhat normal school girl, until her parents were killed by Vitale and Ottomo, with Samson fusing with her to save her life. She is currently homeless and suffering from amnesia. After her amnesia Filia is naive, curious, and is still as caring as she was before as she gave up regaining her memories just to give Painwheel a better life. Samson is a parasite on her head, one that takes shape of her hair. He can shapeshift and meld himself into hammers, fists, and drills.
