Rinnegan Daddy: Sign-In Grants Kamui

When the Demon of the Ninja World is forced to become a top-notch dad: warming bottles with chakra, raising a kid with sealing techniques, and finding his Moon's Eye Plan covered in childish doodles. Meanwhile, Donggua is busy signing in on Madara like crazy: a head pat earns Wood Release, getting the kid to sleep unlocks the Rinnegan, and making Madara's blood pressure skyrocket earns him the Ten-Tails' power! When Madara stands at the Valley of the End holding a child and declares, “From today on, whoever my son says to hit is who we hit!” the entire ninja world is reminded of the terror of being ruled by the Uchiha. Only this time, the source of that terror is a little tyrant with a pacifier!
