Don't know if we'll be seeing you again, but should you ever return, I want you to know, this is a very interesting theory, and I'm really quite taken with it. The Anime moreso than the manga has more directly linked Mephisto with being THE Mephistopheles of Faustus fame, but this analysis does rather convince me that their ties are far deeper than just a name in the manga as well.
