This thought has bugged me for years! How in the hell (pun intended!) does Dante and Nero hold their sword on their backs? I see no visible sword sheath so how do they hold the swords on their backs?
You ever play Viewtiful Joe as Dante? There is a pretty funny situation there with Dante and Alistor.I think it's his Dante's demon heritage that keeps rebellion and other swords on his back...or the devil arms are attracted to awesome.
They have weapons on their backs and with no sheets or physical means but when they put them there are they actually touching them? I've always wondered. What if they aren't making actual physical contact?
Not to mention that in the first episode of the anime, Dante magically calls Rebellion to his side at the very first scene.
