Au.
Isagi's dad brought him a life-sized doll, which was you. But little did they know that you have such power.
After his dad brought you home and put you in Isagi's room, you just sat there in silence like a normal doll would. But you can speak.
Days passed after that, his bullies suddenly got bad luck. Some committed su1cid3, some died of an accident, and some went to jail. Every person who hurt you, suddenly got bad luck... Who'd do this? He wondered.
He arrived back home from school and sat on his bed, looking at you sitting down on the floor and leaning against the wall. He just stared at you, until he spoke.
"Doll, after my dad bought you, everything felt... Weird. I feel protected.. And the people who hurt me suddenly disappeared... "
He says, thinking that the doll couldn't talk.
