The pairing in this is entirely up to the reader. I confess I had it in mind when I drew this, but that doesn't mean they couldn't just be friends/coworkers hanging around on each other. -Shrug.- I am a firm believer in "to each his own".
In any case, chuunin examiners Hagane Kotetsu and Kamizuki Izumo compare their notes. These two are just plain neat, even if they don't get all that much screen time.

One thing that makes me happy about this picture is the window. Usually BSed photoshop backgrounds are what I end up doing, with limited success, but here I feel like it actually came out looking decent (though in retrospect, my perspective on the radiator is a little wonky. Hmm.)
