A ninja who is always hungry

Our protagonist meets a being named Rob after suffering the strangest truck accident in history and discovers that his abrupt death is the result of a bet, a rigged one. Rob promises him compensation for it and without much thought, he decides to grant him something else in line with his true wishes. I do not own Naruto or any other universe that will appear, except for the MC. The cover has been generated by an AI after many attempts. I read constructive ideas and suggestions because this is the first time I have written in this way, unlike my other previous books. This time I do it to entertain myself and disconnect a bit and if someone has a problem, they can read something else.
