Yousuke Yamamoto's life has gone downhill following the death of a close friend, becoming a series of monotonous days that he lives through without motivation. On a freezing night, Yousuke crosses paths with a girl named Eri Yukisaki—only for an abnormally tall, chainsaw-wielding individual to suddenly appear and start attacking her. Despite the frightening sight, Yousuke is enthralled to see Eri fight and becomes eager to help her. Almost killed in the process, he is luckily saved by the girl as the man flees.

Yousuke learns that Eri is a senior at his school, and while she is unaware of the man's identity, she can sense where he will appear at night and has obtained extraordinary strength to counter him. Because of her newfound powers, Eri feels that it is her responsibility to stop the man from hurting others. Having finally regained interest in life, Yousuke pesters Eri to make him her partner, which she eventually agrees to.

Although Yousuke does not prove to be very useful, Eri is happy to have him by her side. As their bond grows stronger, the eccentric pair gradually come closer to defeating the man—however, it seems Eri is still hiding a significant secret.

Let me preface by saying that I am a huge fan of Welcome to the NHK, written by the same author. NHK was a story of human struggle, and not in a fantastical or hyper dramatic way.

Because when I had seen he also wrote a story called "Negative Happy Chainsaw Edge," I figured that he had lost his marbles and wrote something completely unlike NHK. While true that it isn't a 1 for 1 copy of NHK, there's a similar spirit inside of NHCE (shortened for the ...

Complexity comes in many forms. Simplicity comes in maybe more.

Negative Happy Chainsaw Edge is a manga that hinges on an extremely thin thread to drive the story forward. The protagonist – the bored Yamamoto – borders on being so plain that forgetting his face in the next chapter can be a normal occurrence. However, he one day meets a large man with a chainsaw in the middle of battling a cute girl complete with a school uniform that has an extremely short skirt with no battle armour whatsoever. And she’s winning. Since Yamamoto is so bored with his life not knowing what to do, ...

I generally go out of my way to find psychological manga and anime. I just love how thought provoking and mysterious they are. Unfortunately for Negative Happy Chainsaw Edge, that is about the only thing this manga did right. Hard to follow action scenes, strange facial expressions for the guys, unnecessary fanservice, and one of the worst male protagonists I have ever seen all work together to take away from the dramatic and thought provoking plot of this short manga.

Story - 6/10

This is actually the best part of the manga (at least later on). The story begins as our main protagonist, Yousuke, is walking through ...
