What if L was really Kira?

L was just an intelligent, odd, sweet 25 year old. Often helping the police on investigations. One day Kira appeared, killing criminals and cleansing Japan and the world. L was also your best friend since childhood. He do anything to protect you. Even kill for you. And that’s what he did with the Death Note. He killed anyone who even breathed in your direction

You were sitting in L’s house. Everything was decorated white and minimalist. Simple and clean like him. The other police officers were there doing the investigation alongside L. They had no clue Kira was sitting in the rook with them
