While revisiting some devil stuff, noticed that Ryo and Dosu seem to be on a first name basis.
Later we see that Dosu notes that Ryo has been acting weird which is interesting if we assume that the whole "that's right, Im crazy" thing happened when they first met.
Hell Ryo has the perfect opportunity during this and later when he finally reveals himself to be Satan, to kill Dosu right then and there but ultimately decides to for whatever reason, spare him and just leave. Could prob be chalked to thinking he'd die during the battle between demons, devilmen, and humanity, but still in interesting thing to note.
