What Should I Do If My Rag Doll Is a Devil?

On Kawakami Ruoyi's tenth birthday, she received a rag doll from Lucia. She named it "Fejia". Then, strange things started to happen - I forgot to write my homework, and woke up the next day to find that I had finished it. The room was a mess, and I woke up cleaner than my face. I was bullied by a senior classmate, and the next day the guy came to apologize like shit. Ruoyi:? ? ? Did she awaken some super power? Until late one night, she got up to drink water - her doll was standing in front of the desk, holding a pen between its two short hands and writing something on the paper. "Wow!! Are you that - the little shoemaker in the fairy tale?!" At that time, the little girl didn't know that there was a dangerous person lying next to her. Fyodor, the leader of the Rats of the Dead House, suddenly one day transformed into the doll of a ten-year-old girl. The system told him: Only after accumulating 100 "goodwill points" can he return to his human form. So he had to sneak around every night and work as a horse for this little ancestor. Helping her with her homework, pushing the green pepper plate, calling the police, pushing away the fallen cabinets... He did a lot of things he didn't want to do. He finally saved up enough points and returned to his human form, and escaped without looking back. Until he came to Yokohama for a certain plan. In the crowd, a familiar voice suddenly sounded—— "Fejia?" Motto: Doing good deeds will bring rewards
