Dansai Bunri no Crime Edge (The Serving Crime Edge) is a dramatic battle series submersed in a number of sexual fetishes. Despite that last statement, this series isn't really ecchi except for a few select moments. Gotta admit, I like this series even though it is pretty cheesy in many instances. The action is pretty over exaggerated which is somewhat funny but adds great entertainment. You'll get a kick out of this series for it's exaggerated fight scenes and budding romance.
Dansai Bunri no Crime Edge primarily focuses on character development more than it does on fighting scenes. Maybe it would of been a better idea to focus more on the action and survival. The characters are made up of your basic cast from most shonen series. the headstrong white knight MC (Kiri) and the helpless danzel in distress (Iwai). The arch nemesis that has never really tried to kill the main characters but constantly says they're enemies along with a loyal and mentally disturbed partner (Byouinzaka sisters). There are a cast of other below average characters and the only ones that seem to really stand out to me is the blind pianist Hitomi and her deaf Instead, Houichi. Sadly neither of them get any real screen time and are just seen for about eight minutes in total. The characters don't really stand out and are each pretty generic including the cheesy romance between Kiri and Iwai. Their relationship is exactly what you would expect from your average action/romance series. Alone, each character aren't exactly anything special but their interactions is where the entertainment comes in.
Despite how serious Crime Edge attempts to be, what really seems to be the most enjoyable part of the show are the slightly comical battles. The fight scenes are actually somewhat funny. Just imagine seeing a dramatic battle set in a dark hallway at sundown between a guy holding a pair of scissors and a girl holding a needle. That's pretty much the first battle in this series and it might be as funny as what you're imagining. Crime Edge is actually a pretty enjoyable show to watch if you're not a hardcore shonen anime viewer or a very critical judge of anime. It's a bunch of fun to watch and I recommend it. Dansai Bunri no Crime Edge definitely has some high entertainment value.
