HP x Naruto
-Fem!Harry. Hayley Tsubaki Potter is Kakuzu's adopted sister. He adopted her when she was eight and living with the Dursleys.
-Kakuzu raises Hayley in the ninja arts until her eleventh birthday and her Hogwarts letter comes.
-When she is at Hogwarts she keeps in touch with her big brother. She had always looked up to him, because he was there when she needed it. He didn't turn his back on her when she was bitten by a werewolf. And she would always be there for him too.
-Now after leaving Hogwarts due to betrayals, she comes back to her big brother. She comes an unofficial Akatsuki member and they will be told about her being a werewolf so they know why there might be heard howling once a month from the training room.
-Pairing preferably Deidara x Hayley or Pain x Hayley. And please make her good friends with everyone, especially Itachi, Tobi (Obito) and Hidan (Such hilarious times to be had...).
-And whether or not they visit the Wizarding World is up to you to decide.
