Great story, you should give it a chance

Firstly I understand it can be super annoying editing out mistakes. In my novels I have to edit each chapter about 8 times and my chapters are substantially shorter than yours so I understand it might be kinda daunting to edit it all, but don't screw your fans and yourself in order to save time, go edit it or get an English/American speaking friend with good grammar to proofread for you.

Style: Good so far, a bit blocky as far as text goes, but good overall.

EDIT: This has improved a great deal.

Story: Loving it, this keeps pulling me back.

Grammar: As stated above. 

EDIT: The grammar has improved a huge amount at roughly chapter 36, so push through the early chapters if the grammar is an issue for you.

Characters: Interactions and romance feel forced and rushed respectively.

EDIT: Both of these elements have improved.

Best of luck, hope I helped.

  • Overall Score

Decent wish-fulfillment story.  Ok grammar, seen much worse.  I only have a few minor issues with it.

1.  The title is somewhat misleading.  While the MC is able to function as a parasite, he seems to just use it to give stats to his main body.  Its not really a problem, just some people would expect the parasite feature to be more important since its the title.

2.  The MC's attitude is way to hostile.  Even when he is not killing people, he is bashing their personality in his head.  For every little thing that upsets his extreme morals.  I get that he is suppose to be broken.  But if he stays this broken, the story will never be anything more than a series of fights with no real plot.  Hopefully the author will have the MC grow a bit.

3.  The super spiteful MC totally trusts (and falls for) the girl way to quick.  He isn't a harem-seeking MC so his love at first sight attraction to her seems off.  Especially since he was betrayed before.  Its a magic fantasty world though, and the MC isn't human.  So maybe a reason is given for it later.  Though I'd rather have seen their feelings develop over time.

Again though, the story isn't bad.  It doesn't really have anything new.  But no one does anymore.  The story makes sense.  And the MC isn't just a puppet doing what someone else tells him to.  So its better than it could be.

Originality can mend its flaws

Although is not perfect, is pretty good.

Grammar & Writing style: Crow, the author, has gifted us an amazing story, his first story, that's one of the reasons the writing style is so... Mundane, boring, amateur-ish. Still it has to be said that Crow is improving quite fast so if you're going to read it, ignore the several flaws in the few first chapters.

His grammar is also quite bad but as his writing, he's getting better, probably just because he has no proofreaders or he himself skips this part it's important to proofread. 


Storyline and characters: I have to say, this is the most interesting part of this original novel, the originality Crow gives to his story is amazing to say the least, as his first story, the building was mediocre at first, the characters had no actual deepth and the story has several major flaws, but with each chapter you can notice how Crow is getting better, wich is one of the things I enjoy the most, at first, the main characters were just simple minded fools, now they have become interesting. The whole premise of a tortured man becoming a parasite is quite good.

Yeah, it's obvious for everyone that 'Once human, Now a parasite' has several loopholes, flaws and gramatical errors, but every first story is like this. I will read this story to the end, and after that Crow will have grown to a good writer, I assure you, the next story he writes will be 100% better than this, this is the beginning of a novelist who relies on his originality. Can't wait to see his next chapters.

The story is so good, the MC is op and the pace of his growing is not so slow, it's just perfect.

I started reading it and couldn't stop until it was 4 am. However, i only realized it was 4 am because I had already finished reading all the chapters and had time to look at the clock xD.

I find the story somewhat tolerable. The thing is, I find the grammar to be appalling. I think at around chapter 5-8, the author left a note saying that he/she would be switching to 3rd person. After that in that same chapter, I found parts where the author would change POVs mid sentence. Also, it doesn't take a genius to find numerous mistakes such as: capital letters (both a lack of them and misuse of them), words written using an incorrect tense as well as the placing of commas. 

I might also add that spelling is terrible to the point that I have to correct whole sentences in my head to make sense of some of the sentences. 

  • Overall Score

  I really wanted to like this story because it seemed good at first, but then it just got stupid after he met the demon girl.Spoiler: Spoiler

The reason I couldn't tolerate it was because of the mc's whole appeal was how he was betrayed and wouldn't trust anyone again, but the first person he meets he tells her his entire life story. At that point I couldn't continue, I could understand the mc revealed it further down the line but for someone who was recently betrayed he trusts way too easily.

The author did try to bridge the gap by writing about how the mc feels some sort of pull towards her but the mc was betrayed by someone he love which I believe would give him an even more cautious view on anyone he feels the same way towards. It would have been so much better if the mc slowly started to reveal who and what he was slowly as he began to trust her more, but instead everything was just released in one go; I feel like it was a missed opportunity.

I was unsure at first if i would enjoy this story but i quickly began to enjoy it. unfortunately it started to become inconsistant and less enjoyable after about 50 chapters. I would suggest people read to the (spoilers) fight with the lightning dragon and assume our MC dies of his wounds to get the most enjoyment out of this story. The first part would get 4 stars from me but after that it would get 2.5-2 stars

I have read it till latest chapter 199 and i can say with confidence that this was one of the most addictive and loving novel that i had ever read .

In each chapter, i can easily visualize the content. 

The details are so real. 

Moreover, in the beginning the chapters had horrible Grammer but now its amost perfect to read.

I had enjoyed the read very much. 

Thankyou author for give us a wonderful story.

I can't read, grammar is so bad that my eyes bleed.

Stupid main characters, stupid villains, horrible grammar. You don't even know how to differentiate the word man and men. Dude, read more of the classics in English and then rewrite this story with some decency.
