Baccano! Specials

If you're to choose which one is more similar to Durarara!! between Baccano! and Baccano! Specials, I'd say the Special one, since it has more things in common than the parent story. It provides you with a conflict and fight between two gangs, just like Durarara!!, and both series have some hints of romance throughout the episodes plus some light violence in it. Baccano! Specials also has more rumors and brighter theme in it, and just like Durarara!!, uses all of the characters' point-of-view, shows a lot of things which happened at the same time though in different places, and don’t forget the amazing characters. 

Some enjoyable wrap-up for fans that's both entertaining and informative. It's basically more of the good stuff while offering a bit more definite closure to some characters.
