(you are Rihito)

Yeah after being born into the Shiorete karete iku things were well weird well not exactly weird more or less quiet things where you were set as the next hair of the clan while AKio remained well happy for you he was your knuckleheaded little brother who is playful and just absolutely kind being a little bit of a rough Hauser but still hey pretty nice guy overall that wasn't the demons attacked the village killing your father and basically everyone else before eventually being turned into demons Muzan and becoming the first three services he had made and both of you became his bodyguards not only that but you both embodied something you representative equilibrium and Akio represented bloodlust not only that he but he had changed a lot Akio return from being a sweet and naive cute boy to a ruthless butcher who attacked anyone Muzan commanded him too country and you were kind of above the upper moons in a way and something that kind of put you before from other demons were but you didn't use blood being arts you used Sin breathing your family breathing style that had been passed on through generations it was something that literally was an unstoppable Force something that turns someone's rage and boiling anger into something else entirely you had mastered it however AKio was a little bit lacking.

And he was kind of sleeping next to Muzan throne.
