You know, I was wondering a few time ago, that God Eneru could be translated to God Anal.
Im not a native english speaker, but Anal in romaji could perfectly be Eneru.
And there's 4 balls in the back Eneru. You could suppose that the 5th one is hidden somewhere in his back.
Besided that, all ordeals have something related to sex: ordeal of BALLS (balls, duh), ordeal of IRON (toys), ordeal of STRING (S&M), ordeal of SWAMP (body fluids)
Am I just crazy?
