I'm never super well-informed about general fandom opinions, but I'm under the impression Hiromi's popularity is in part because of how minor he is? I don't think it's ever been about people seeing some immense complexity or importance to his role -- Hiromi's actor just did such a great job bringing a charismatic earnestness to an underdog hero of justice with a particularly sweet Rider suit, and that's literally all anyone needed to fall in love with the guy. The whole reason his role was even as big as it was is because the show's own staff fell in love with him before the fans did, to boot.

I'm not quite as big a Demons fan as some people, but I am a huge Knuckle aficionado, and Zack's surprise popularity in Gaim was a similar enough situation that I can relate completely. Some side characters just end up being a lot of fun to root for, you know?
