An attempt to making a signature/banner of Aqua of Birth kwa Sleep, the background isn't black, its PNG so try dragging it ;D (If wewe want to use it, go ahead :D) Enjoy :]!
Samuari Legends Musashi should be in Kingdom Hearts 3 cause there made kwa the same companey and also the worlds in Musashi would be great for sora and the others to explore. And Samuari weapons. That could be used as Keyblades.
