Very different feel, there's no historical drama or (vaguely) realistic combat. Busou Renkin is all about a guy getting in way over his head in a secret war and becoming kickass thanks to his refusal to give up. Also about a hot chick with a scar across her nose, but like any good shounen fighting anime, it's really about manning up and fighting the good fight. 26 episodes is a good fit because the simple-fun formula would get old if they dragged it out longer.
