Kotetsu Hagane is a Chunin from Konohagakure best known for basically living at the village's Main Gate alongside his partner Izumo Kamizuki. The two are responsible for checking who comes and goes, and they've become pretty much inseparable—you'll rarely see one without the other. They're the kind of duo that finishes each other's sentences and has clearly spent way too much time together, which honestly makes them good at their job even if it's not exactly the most exciting posting in the village.
