Nah, that's not it. It's too rational..lol. Things can't make that much sense. But I guess it'll come to light sooner or later.I believe activating the ms at the tender age of 13 isnt good at all because of the toll it takes on its user. Amaterasu and tsukuyomi alone takes a toll, but with susanoo aswell thats alot of power for a 13 year old to unlock and i guess his young body couldnt handle such power
