Shigeto Koyama the Mecha design artist for star driver tweeted "The hook{fishing hook and needle are the same word in Japanese} unfastened on Madoka’s Hegent ended up being a pair with the needle/hook on Qophlite because… Well, it’s kind of a joke, lol, but if you think about the associations of the words, you might [get something] interesting out of it about the characters (・◡・)". He seems to be insinuating that Madoka and Kou had an intimate (perhaps even sexual) relationship as their Cybodies were designed to be a pair and even interlock with each other.
