Lets be honest just like Durarara, this show is full of mains, so whos your favourites? For me it's got to be Isaac and Miria. Lad and Firo are awesome too, but I don't want to start naming everyone

Favourite character?
___________________________________________
I don't really have a favorite, since they're all awesome. However, if I had to choose, it would be Firo and then Luck as a second favorite.

Isaac and Miria were definitely my overall favorites, they were just way too funny. I can be pretty over-the-top like Isaac myself, so his personality appealed to me a lot.
Other favorites would be Ladd Russo and the Rail Tracer, both for pure badassery.

I'm agreeing with Isaac and Miria, they were really funny and great comedic breaks,and they're those random idiots that make a show really enjoyable.
I also can't remember the other characters too well since I've only watched it once and there are so many.
I will say if we were talking about favorite characters as a couple, I would definitely choose Issac and Miria, but only because they're so stupidly hilarious.

Rail Tracer and Firo. Although the OVA definitely made me like Jacuzzi a little more, dumb name and all. ^^
Claire Stanfield~ gotta love the Rail Tracer!
AND little Czeslaw Meyer
I sometimes like to believe I'm witty, so check out my blog!
Gotta be Firo~
I have to pick Isaac and Miria. They were easily the most entertaining characters in the show. I doubt that it is a simple task to take a show that is as bloody as Baccano, and make me laugh like I'm watching Shin Chan.
Claire Stanfeild all the way. My name is Claire, I'm a redhead, plus i think he's a real kickass character. GO REAILTRACER!
I'm just one hell of an otaku.
This show really is full of main characters, and while Isaac and Miria are close to the top, I have to say my favorite is Chane Laforet. I guess I just have a thing with tsundere girls.
