Kumagami is at times sarcastic, as is evident from the ‘reports’ she writes in a few of the episodes. This is different from Kanuka’s report, which is more matter-of-fact or angry in tone.
There is some ambiguity regarding her relationship with Utsumi^A). I wouldn’t be able to say anything definitively regarding it but, honestly, she probably wouldn’t be able to either. That said, something was made somewhat clear…although she’s a bit confused about her feelings, she definitely doesn’t like him. One piece of indirect evidence in favor of this is what she said to Izumi: ‘I haven’t found the right man.’^B)
This at least indicates that she doesn’t think of Utsumi as being the right man. I’m probably just pointing out the obvious here.
Another point of interest regarding her: she starts as Unit 2’s backup (in the manga), but eventually replaces Shinohara as Unit 1’s. This is particularly odd as they never switch back…even after the manga ends, it’s implied (partially) that she remains Unit 1’s backup. I find this odd and interesting because I’ve never seen a change like this remain permanent in anime/manga. Even in the Patlabor TV anime, Shinshi is Ota’s backup for a single episode.
