I'm planning to make a animation video for pewdie's latest fanfiction reading video.I want to monetize the Fanimation video i made but i'm worried about youtube putting some ID claim/Copyright Infrigement on it and remove the audio as well as my channel. I haven't make my channel yet but i need to clarify some stuffs to my self before i start.

Should i ask permission pewdiepie and the writer for using their work for my animation video first?

Thank you for reading my problem
