Chuchuba girl at the back of the motorcycle, tell us your secrets

But who was the girl tho???? She just suddenly appeared and now she's out of the picture. There seems to be a bloodied bucket at the room where the MC knocked to ask for help. Where is she????? Did she get her organs harvested? Is she the chapter 8 barbecue meat????? A ghost? A figment of MC's imagination lmao?? Or maybe the real her is the chuchuba icecream we delivered along the way?
