In many of the songs created by Sparkles* it seems that 'eyes' are often mentioned within the lyrics. This poses the question as to why? Is he trying to direct us into noticing somebody, maybe Cassandra's eyes? Or are eyes an important part of the story? The significance seems to tie in with Area 11's eye logo. Could there be some sort of eye related power like Geass power? Or Could a mecha or other electronic device/software be controlled using the eyes?
