Gungrave starts out with around 15 episodes of pure Mafia anime. It's a lot more serious and is more reallife like (Those starting episodes have close to none science fiction added. No fire shooting, magical animals, monster, you get the picture), but if you love mafia anime like KHR, you will love Gungrave.
