It's actually quite common to say that if you look back you can't escape anymore, and it was orpheus who looked back, not the girl (don't remember her name) so I don't think it is related to this specific myth
Akane looked back didn't he? And when he did she was gone? I don't think its exactly like the myth but i thought it was kinda cool haha
anyone notice that sly Orpheus reference in the last chapter?
