Oh fuck, you're a Black Lagoon fan too?
I watched it relatively recently like 20 years late, but I loved it. Revy, Dutch, Balalaika, Shenhua, all the side characters were super interesting, and the animation was so good. I loved all the mature themes and the way the characters talked that wouldn't fly at all today. I ended up watching in english but I don't really regret it since the dub was actually very good, though I wonder if the dialog changes much between versions.
Revy's back and forth with Shenhua is hilarious in english. I love her whole blades on a wire trick, especially when she's threatening the out of town cowboy looking guy and explaining how things work in Roanapur. In the scene where they're raiding the safehouse with all the other bounty hunters and she gets injured and almost died, I was going to be mad as hell. She may be a villain of sorts, but I want her to LIVE. Maybe im a bit biased because I love red and her design is full of it. I love all the detail you put into her clothing, all your lines are super clean.
