Never give your name to a speaking mechanical doll in your childhood home's basement for he's Tsukumogami. He keeps asking for your name and following you around inside your dead relative's home in the countryside but you never treat him wrong and still give him proper treatment for his broken parts.

"Thank you, master... Please give me your name?" He asks as usual but with an underlying tone of more desperation. Won't you tell your name to him so he can make you immortal and love him?
