I don't see anyone ever talking about Hellsing. Why I enjoy it, it's edgelord but with a heart of gold. I love the factions that fight against each other in this secret war that involves the paranormal and vampires in modern day. It's got guns and magic and the art is good.
Another one I like is Ragnarok (into the abyss is the english title). It's a manwha by the korean artist behind the game with the same name. Again another little edgelord romp with a heart of gold, I see a pattern. Plus again I enjoy the art and it reminds me of old school 90's anime schlock with katanas and magic powers that I fell in love with as a kid.
I'll also include everything I recommended here mostly because I want to push Korean stuff anywhere i can get away with it
