Negative Happy Chainsaw Edge is a romance, action, comedy manga that tells a deep story revolving around the lives of Yamamoto Yousuke and Yukisaki Eri.

The story is short, filling only 8 chapters, each about 45 pages long. However, despite this, it manages to tell a deep, emotional tale about two high school students. 2nd year Yamamoto is seemingly a slacker who is bored with life, but in fact, faces deep mental troubles, caused by his friend's death and his low self-esteem. 1st year Yukisaki at first appears to be an outgoing girl, but much is hidden beneath the surface. As the story progresses, each character struggles with his or her own problems, while at the same time, faces each other and the mysterious Chainsaw Man who appears every day at night.

The story imparts many deep, serious themes through the thoughts of Yamamoto and as he interacts with Yukisaki. Most revolve around the idea of an ephemeral and short life. But no fear, Negative Happy Chainsaw Edge won't leave you going emo about how your life will end in a few decades. It also shows the bright side of living as well.

Despite the general seriousness, many small comedy scenes left me laughing, so there wasn't any heavy atmosphere as I was reading Negative Happy Chainsaw Edge. Such scenes include Yamamoto's ecchi, visualized thoughts and Yukisada's well aimed kicks at Yamamoto when she's irritated.

The art was drawn very well in defined lines; there isn't any type of smearing, except for some parts in the background. What's noticeable is the way the mangaka draw the male characters when they are surprised: they open their mouth wide, their faces elongate, and you can see each of their teeth individually. It made the characters look somewhat ugly, but you gotta admire the mangaka's detailed attention to teeth :P

Overall, Negative Happy Chainsaw Edge is highly recommended. The story was serious and touching, yet well-placed comedy scenes prevent the mood from being too heavy. A nice epilogue would be nice, but don't get me wrong, the ending's very conclusive and satisfying.
