this whole manga, the protagonist try to put up a brave face, always being funny and always wise cracking, but i can feel, threading through his unsaid words his sadness and his grief through his friends' death. to me, the chainsaw man is the specter of depression that both of them need to fight everyday or else consuming them. only by together, can they keep it at bay.

a great read, do please read.

Mmmk...This manga is either really good or just above average, I can't tell.
It's safely good [7/10-ish], as even if you just skim it it's got the epic scaffold of a guy watching a girl who, every night, fights a chainsaw-wielding, black cloaked man, temporarily getting physical superpowers during the fight. (At least I don't think she has them during other times) It's got that kinda cliche, exploitation that everyone loves with a title to match like the idea behind 'Hobo With A Shotgun' <--- It's a HOBO with a SHOTGUN.

Now, the question is, is it great when you look deeper (e.g. Penguindrum) or does it fail horribly in that respect like some amateurish 'deepfag' stuff out there (e.g. the limbo scene in Harry Potter's 7th book, {Basset fans are scary, so I won't manage that})?

I...have no idea. I think looking a little deeper at least gives it 1 more out of 10. But I didn't really like any of the characters. No, that's wrong. I'm interested in at least the dead friend and the final chapter where the guy (you'll know who when you read it) is talking. But I don't think the characterisation overall was done competently.

Perhaps I want this to be a 10/10 because it's the author of Welcome to the NHK! who managed to make me feel depressed for days after just reading a few chapters from the beginning and end.

Bottom line: Despite whatever makes this good, the characterisation was bad and the romance was bad.

EDIT: Art was pretty great. especially cover art.

I think the live-action version of this could be done really well, depending on how they approach (I'm thinking Kill-Bill-esque) but I don't think I'll bother checking it out bigrazz

I really liked this series for what it was. I wish they could of had one more chapter though after to just show a little progression in the relationship. Like after its was done they got to comfort each other or something cute. Over all a quick short read that I recommend

feels like random nonsense pretty much from page one
Life sux...well yes it can...lets all be friends and love each other
do we really need 8 chapters of weird to tell us that?

its like the musicguy said in the manga
use vauge language and images and try to make it seem deep
then ppl will overanalyze it
and appreciate it
that one conversation in a flashback sums up this manga [and nhk]
so in a way I like does not try to be something it isnt

the biggest problem for me is that i dont even care one bit about any of the characters
He is uninteresting and emo-ish
she is tsundere emo with irritating changes in her breast size every other page
but its way too short for me to care about their tragic past
its not built up so that i really care about them
maybe i just cant stand emos

This manga was pretty good, it had a lot of symbolism and deep emotions. However a lot of people might have a problem with this manga if their not looking for symbolism in a story with no definite or solid series of events. Some might feel the ending was rushed, but I don't think this series could have gone on too long with the main characters fighting the same enemy over and over again.

well, 7, I guess, plain beginning, plain ending..
besides, I think it is not very deep.. some symbolism is used, but it should not be very rare nowadays I guess..
Some adult contents, 4 pages at most as far as I remembered..
finished reading it in 1 hour, a reread will hopefully be done, but just for the middle and latter half.
the ending is too lustreless.
2 volumes is a good length.. what should be expressed is done, it is OK.

Thanks, will appreciate your answer.

Very deep (by manga standards)

This manga is very deep, by manga standards of course. Needless to say, I'm very used to reading somewhat shallow manga with just action and/or cheap romance. This is very refreshing to say the least. I've come across it a few times on OneManga (via the "Surprise Me!" button) but I was turned away due to the weird title (Negative Happy Chain Saw Edge...seriously?) and terrible description.

Eh, some readers seem to be confused as to the nature of the Chainsaw man. It didn't take me long to realize that
Spoiler (highlight to view)
it was a metaphor
, but maybe that's because I've seen very metaphorical texts before (try understanding Haruki Murakami [a book author]...hah!). That was made clear when
Spoiler (highlight to view)
Eri described that the Chainsaw man not only fitted her imagination, but grew stronger or weaker along with her emotions. There were also multiple references to him as the cause of evil and sadness of the world.

Overall, I definitely recommend this manga. Very original, most original manga I've ever read with no cliches (none that I could spot) at all. You should definitely read it if you're looking for a break from the typical braindead shounen/shoujo manga.

Now this is a different type of manga, one that is extremely new and refreshing. It reflects delicately upon a boy who is trying to find the true meaning and purpose of his life, and a girl who despite all set backs tries to fight of what she perceives as 'bad' ness.
I suppose we all tend to feel somewhat like that at various times of our life, thinking about the purpose of our lives, trying to find some place where we belong, wondering if anything exciting could ever happen in our boring life-- This manga certainly does show us all these qualities, and is probably a unique experience to everyone.
Definitely worth reading.

What a heart warming joy to read. Reading this manga left me on the edge of my seat. An enticing read, that never looses your interest, with pitch perfect pacing. (the lead characters are also really really lovable)

If you like manga with action, chainsaws, awesome awesome romance, character development, and amazing plot... than definitely read this manga. If your not into that kind of manga, I bet you'll still love this ^. ^

it's a symbolic piece of work...its about a boy trying to find meaning in life, a girl trying to find something or someone to grasp to and the death of a schoolmate...its not depressing at all btw
the art is fantastically elegant...the story is deep and it makes u ponder about things and life in general...lots of symbolisms...and obviously quickbrownfox didnt get it, so dont consider his comments as valid...and yes, quickbrownfox the enemy's motive is explained and that happens way before the last's not a hard manga to understand actually and everybody should read it in my opinion...

p.s: somebody should change the description for this doesn't do justice to the title :/// makes it sound too shallow
