TN: Most part of the other character in the novel is depicted from a non-human perspective so expect something that is completely different from the common sense of human.

A soul was employed by a higher being to help him manage his world. How will our protagonist live her life to the fullest while also fulfilling her new duties?I don't own Naruto. I adjusted the story to my liking. English is not my main language so don't bother about grammar mistakes too much.
