Memoirs of an Imaginary Friend

My name is Budo. I have been alive for 5 years. 5 years is a very long time for someone like me to be alive. Max gave me my name. Max is 8 years old. He is the only human person who can see me. I know what Max knows, and some things he doesn't. I know that Max is in danger. And I know that I am the only one who can save him.
