Kiri Haimura has an unusual fascination with cutting other people's hair. One day, he encounters a girl in a western style mansion with incredibly long hair named Iwai Mushanokouji. Kiri is of course, overjoyed over this fact and tries to cut her hair, only to find out that it can not be cut due to a inherited curse and grows at a ridiculously fast rate. It also turns out that Mushanokouji is being hunted by descendants of murderers who are trying to kill her (using cursed weapons passed down by their ancestors called "Killing Goods") so that they will get their wish granted. A little while later, Kiri learned from his grandfather that he had an ancestor who liked to dismember and cut up people with scissors called "The Severing Crime Edge", which Kiri has inherited. Now, Kiri has to protect Iwai from serial killers with these scissors.The Severing Crime Edge (断裁分離のクライムエッジ)note Dansai Bunri no Crime Edge is an ongoing seinen action manga that debuted in 2009 written by Tatsuhiko Hikagi and published by Monthly Comic Alive. An anime adaptation by Studio Gokumi aired as part of the Spring 2013 Anime season lineup.The anime was simulcast on Crunchyroll and is also on The Anime Network.
Tropes found in this series
Absurdly Sharp Blade: Kiri's scissors can sever body parts, something ordinary scissors obviously can't do.
Always in Class One: Kiri starts off in middle-school class 2-A. Despite not going to school for years, Iwai quickly ends up in that class as well.
For the killing goods authors, killing the "Hair Queen".
Morality Chain: A minor one in the form of Insteads, people who have resistance to their killing abilities that Authors can enact their Goods' unique abilities on in order to ease their desire to kill and maintain their psyche.
In Cut/episode one after Kiri fails to cut Iwai's hair for the first time, he begins petting it while commenting that he 'really loves this hair'. Iwai's reaction is purely this trope.
Yamane's "pretend killing" of Houko involves a lot of gratuitous blushing and licking.
The Dulcinea Effect: Kiri knew Iwai for approximately 48 hours at the point he decides to defend her from the serial killers out to murder her. No, not kidnap and sacrifice her, but kill her on the spot. Whoever does manage to gets the power to break the laws of nature, and presumably have one of their wishes granted. Admittedly, it doesn't take much to want to prevent a young girl from being brutally murdered.
Evil Weapon: The killing goods give their authors urges to commit murder.
Fantastic Arousal: Author and Insteads tend to experience this during a fake killing.
Freudian Excuse: Most of the Authors have one for why they're so willing to kill Iwai. Whether they're good ones or not can vary.
Yamane was influenced by the spirit of her Goods' original author, and has been left incredibly introverted and emotionally damaged as a result.
Ruka's is that she didn't get the role of the princess in her school playnote She says that her jealous classmates made sure to vote her out of it because they didn't like how close she was to Romio, who was very popular., so she didn't want to ever have to feel such loneliness and humiliation ever again.
Emily suffered an incredibly abusive childhood, apparently taken care of by some psychotic human traffickers who only kept her alive for her potential as a Goods Author. Then her adoptive father came along and became the first person to treat her kindly. So she's willing to kill Iwai for his sake.
Hypocrite: Witchie makes fun of Kiri for his power to amplify pain, and apparently get off on it too, when she's the one who works to create serial killers and ensure that they have kids who can become Authors in a sadistic killing game.
Rapunzel Hair: A deconstruction. Iwai had her hair cursed. It cannot be cut by any means. That leads her to quit schooling, and well, the inconveniences of having hair that long. Fortunately, Kiri's scissors is a cursed "Killing Goods" and cut Iwai's hair really short at the end of the first chapter, but her hair grows back to its original length in a span of a night. Episode 3 shows it grows right after midnight.
Witch: Oh my, you're so flustered. Is not your first is it?
Kiri(After she leaves): Of course it was my first.
Self-Made Orphan: Yamane killed her and Houko's parents due to being influenced by the spirit of her killing goods' original author. Houko decided to take the blame for it so Yamane wouldn't be burdened with guilt.
Ship Tease: The scene in chapter 21 where Yamane gives Kiri a much-needed blood donation is rather... suggestive to say the least.
Sneeze Cut: In chapter 10, when some of Kiri's classmates wonder if Kiri tried to confess to the class president, Kashiko, the scene changes to Kashiko sneezing.
Spit Take: In chapter 24, Iwai spit-takes when Emily asks if she and Kiri are in a relationship.
Super Breeding Program: Gossips pairs authors together to "mate" in order to create a powerful Order-Made authors. The children who are too weak for Gossip's purposes are disposed of.
Tears of Joy: In the first chapter, Iwai cries these due to being happy when Kiri manages to cut her hair with his scissors.
There Was a Door: In chapter 6/Episode 3, an author of a killing good in form of a sledgehammer uses it to break through the walls of Iwai's mansion in order to murder her.
Tykebomb: Order-Mades. Gossip apparently goes through the trouble of creating serial killers by driving people insane with drugs and the like, and then arranges for them to "mate" in order to ensure they reproduce. The kids who don't become authors are tossed out, as well as the weaker Authors. The select few to be chosen by Gossip are the most powerful Authors.
