Black Lagoon: Roberta's Blood Trail

Just finished my Third rewatch of Black Lagoon, my 7th favourite anime series of all time, while 7 may sound low for some that's actually pretty damn high for me. I'm surprised I haven't logged its OVA before, maybe i never thought to look. Anyway in a blanket review to someone who hasn't seen it I'll say it's a Gun-fu action series that very quickly becomes more layered than it first appears. It has some of the strongest female characters out there and also features the only character in anything that scares me.
