Well I didn't see a topic like this so here it is.
I have a question. Does anyone know about yuri manga about a doll that was constructed by her 'sister' that is going to school in which the sister is a teacher. I remember that the doll fall in love with that classmate and there was a chapter that she had to do a quiz and she accessed the net and there was that, that other classmate found out when the doll girl was recharging and a lightning struck. If anyone remembers please tell me I looked everywhere and can't find it. I think it was on a cover of yuri-hime.
Thank in advance.
