>>3346574Miwa draws his swords consistently but so does Ishikirimaru's and the Samonjis/Nihongou's (at least last I remember) artist as well. Toboso draws Hyuga every once in a while especially since she's a fan of the series and wouldn't neglect what's basically her canon fan oc. Off the top of my head, the artists for Mouri/Hakusan, Nansen, Daihannya/Koryuu, and the naginatas will sometimes post doodles of their characters too but nowhere as frequently. That said, even if other artists might not doodles their characters outside work as much, I think seeing how they draw and detail their characters in the artbooks usually tells you who cares a lot for their swords and who might be more in it just to get paid since it doesn't feel like each swords page is made equal.
