Thank you!! I've seen this image for quite some time, though translating with google would give very weird results..
All this time i thought that Niikura's eye was some kind of rejected concept around her character but turns out Nagumo had just drawn it on her!
Also, it's mentioned that Nagumo talks like an Otaku, is her way of talking considered "Otaku-like" in the original japanese version of the manga, or was that changed completely?
