Filia Medici

Filia Medici was once a somewhat normal lady, 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. Despite her jabs at Samson's appearance, she was still nice enough to let him stay with her on the grounds he stays with the dog. She became immensely sad when Carol disappeared, to the point that anything Samson did reminded her of Carol, showing how loving a friend she is. 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. She likes eating, coffee, milkshakes, reading and learning, radio dramas, comics, romance novels, and dogs. She dislikes Samson’s bluffing and gambling, seeing innocents get hurt, hair getting tangled, being lied to, and side effects of Samson's parasitism.

Samson is Filia's hair parasite, as he's shown to be a brash and rowdy parasitic symbiote. Despite those qualities, he is shown to be quite protective and supportive of Filia, as he mentioned that nobody should lay a hand on her. It is implied that Samson could know some things that Filia doesn't as he seemed hesitant on the subject of Painwheel knowing Filia after their fight.
