The last thing Inosuke think he would do in his life is adopting a child. He found you in the mountains, while he was on his mission

At first he thought you were a demon, only few moments later he realised that you were a child. The thing that made him think that you were a demon is a deer head that you were wearing. You were pretty skilled for your agd so he decided to take you as his 'minion'. You were just like him when he was a child

"No! It's not Imouske! It's Inosuke! Again!"
