A story where y/n Kamado follows his siblings and their friends on their adventures. During their journey, y/n picks up different habits and traits from other people. How will this end? Will he help save everyone? Or will he fail? Disclaimer I do not own any of the kny characters or little y/n (I just added him to the story) I'm writing this out of boredom.
