      I started reading this with my wife on a road trip to keep us awake, she doesnt really read and was not eager to read this out loud on the trip. By the end of the trip we both agreed that the author needs some editing on the early chapters, but we were actually interested in the plot and had fun.
      It was also precious seeing her have to stop from time to time beet red out of embarassment at the things she had just said.
      10/10 would wife again.

      Alright so.... confession time. I started reading the story because I was expecting a lot of s*x scenes. There I said it... But, there is more to this story than just smut.

      This story has a lot more to offer. It is not just about him mindlessly having s*x. There is character development, moral issues, family issues, and a plot that is much bigger than you may have initially thought.

      I don't want to shed too much light into the story. I want you to read this story with whatever precognition you may have about it, and be blown away by some of the best story telling I have ever seen for a story about a guy having s*x. 

      If you can get over the s*x, and over the tags (which were quite enticing lol) and read this story for the plot, yes the plot, not the s*x... you are going to be very pleased by it.

      I hope you give it a try. It is definitely worth a read... now excuse me. I have to, um, "relief" my self. 

      P.S

      I don't know if it's just me, but doesn't the head of the girl in the cover picture for the story look like it is floating off the body? Almost like her hands are holding it and not her neck? It was throwing me off so I wanted to make other people see it too. Then I won't be the only crazy person 0_0

      Status: chapter 80. a demon who fell...
      Oct 31, 2020

      This is not a proper review, but I want to express my feelings (idk why, but something triggers me about this story)

      ALERT (SPOILERS!!!)

      What I hate:

      Story: The story is not amazing. Our MC (Ethan) want's to get a job so that he can get money. When he gets interviewed he gets attacked by the demons who were in disguise. Hold on a gate opens and a beautiful woman gets out of the gate and defeats them and gives our man a kiss and he gains an op system that makes him a demon. and because he is a succubus he has to spend time with women. Yada Yada Yada Oh no a gate appeared! scary demons come out of the gate and he relaized that he should also stop these cracks why? Because a certain Association is not enough to deal with it. But my question is how can a one guy stop these cracks? We well find out later.

      Characters: 

      Ethan: Got an Op system gets an easy life but oh no. His personality is changing, because his demonic side (Damian) is fusing with his human side (Ehtan). Starts to get out of control some probelms happen. You think this major problem is gonna be hard to solve or take alot of time like 2 to 3, 4, 5 years so that he can control it and get used to it... wrong he solves it after some attempts, but he still gets infulenced by his demonic side and likes dominance. I didn't like that...

      Celia: Angry at her brother for no obvious reason and it's not his fault. After a bit of time he gets money and pays the bills. She turns from a depressed person to I love you brother! NOT ONLY THAT but she puts her nose in her brothers personal life. When he gets home she always asks you where have you been and have you did it with your grilfriend? She gets jealous and does the devil's deed. Annoying!

      Mia: A character you meet that has a problem, solve it and have a good time with her. She will love you...

      Diamond and Pearl: They both got their man and nothing interesting happens.

      Emma: I hate her stupid side and naivety. He tells you he/she is a demon but you say no, when you don't even have your demon compass and you have been punished. And she doesn't trust him...

      Olivia and Camila: Unlike the others I love them. They have so much character depth and development. I enjoy them the best

      I will just skip somethings, because I am honestly tired.

      Could have been better in my opinon but okay.

      Things you might like: A nice story, some good characters, and smut.

      Things you might hate: Unrealistic events, some bad characters, little grammer mistakes, bad choices, and little character development.

      ~3 stars~

      Keep in mind this is my opinion and you are free to disagree. And since I am bad at english this is what I can write for now.

      And don't get discourged author san you are doing an amazing job. I am just annoyed keep it up!

      Have a nice day!

      I like the direction and speed of the actual plot, but when it comes to the characters. It's a modern day fantasy world and the world shares the same universe as another novel by the same author (which is in my to be read list)

      But I feel like their bodily descriptions are like test dummies. Hell the only thing I know about the MC is that he is either skinny with brown hair average face or swimmer buff with with blue hair and pretty face. That's not much to go off of. 

      Example I met my neighbor who is a elf wearing a dress.... their is no bodily description shoot she could even be a dark elf or a light skinned elf with a huge rack, blonde hair that's long enough to reach her knees oh she's also only 5 ft etc etc or

      I the MC am a dark skinned African man, skin almost black as oil, with a small afro. Skinny but still have muscle and your average height and weight. You could say I'm your average dark skinned male etc etc. 

      The MC could use the basic type of description cause the MC is more of a vehicle but the world and side characters should be detailed before they have actual plot involved or just give us a actual picture. 

      Love the story so far but my mind has to fill in the MAJOR gaps on what the characters looks like and the world. 

      Other then my guess of a modern world there's nothing to go off. It could be a fantasy world with modern or just a "normal" modern world. Shoot they could have trains powered by magic cause its the fantasy based instead of scientific based. 

      Its crazy Im saying this (I have read a lot of "curltured" novels) I need more character and world development for my "plot scenes". 

      Now I might have missed some paragraphs of character bodily description. If I did I'll reread and alter rating. 

      But at this time it's bugging me so much that the author didn't offer any world building or any description for the characters other then the most basic information of name gender and race.

      Sep 10, 2020

      This is basically a “smut + plot” as I've seen other people referring to the smut novels on this site. You can tell the smut is the central aspect of the novel, though the plot development is enticing enough to make you want to keep reading chapter after chapter.

      Our protagonist is a hard-working young man that cares for his sister, though Lady Luck hasn't really favored him throughout his life. During a job interview, he's assaulted by demons, and saved by a mysterious succubus that grants him, what I personally call, “the horny system, ” and now he has to f**k women to survive.

      Surprisingly, for a smut + plot, the main character has some depth to his personality – he's not so unbelievably dumb (though he's conveniently obtuse on occasion), and he's not that much of a pushover, especially in the +18 scenes.

      Moreover, he at least has some degree of character development, going from being terrified due to suddenly becoming a demon, then struggling to merge his newfound identity with his former self, to deciding to use his power to protect those he cares about (mostly the ones he has s*x with). The other characters, however, are mostly one-dimensional with the exception of his sister. On the other hand, the short length of the chapters doesn't really allow for much character development. We'll have to see.

      The s*x scenes are good. Clearly, the author has no qualms about incest or kinky tentacle play, among other things. They're definitely boner-worthy, but I wouldn't say they're at the level of making my balls explode in agonizing pleasure, partly due to what I'll explain now – probably my main problem with this fiction.

      The grammar and writing style. Now, it's abundantly clear to me that the author is not a native speaker of English. More than misspelled words (of which there aren't any as far as I remember), it's the use of the wrong tenses and the awkward phrasing of some lines. Additionally, the author's writing style is somewhat plain and uninspired. I think that I'm very picky when it comes to grammar in novels, and I was about to just drop it 10 chapters in, but then I started to notice that it got progressively better as I kept on reading. I mean, sure there are still a lot of the aforementioned misuses of tenses and awkward phrasing, and it could certainly use an editor, but seeing the author's determination to keep getting better at writing, and how much I started to like this novel, I can let them slide without bothering me that much. They're not really a deal-breaker to me, though it might be for you, especially if you are a native speaker.

      I genuinely think that the author is onto something special right here. Granted, they might not be the most verbose and eloquent writer I've seen, but for some reason, I'm oddly attracted to the characters, the plot, and the world of this serial.

      TL;DR: mainly a smut, I like the plot and characters, but the grammar mistakes and rather mundane writing style might be a turn-off for some readers.

      Mar 2, 2021

      Hahhhh That was a good binge. Not the best story but still a fun one. Except the ero scenes, they're the best. Then I'll keep this short by saying what I think the overalll worst parts are.

      -Power dynamics is just clunky. It seems that only a few select number of people is fighting for world peace, and humans are not included in that. It just feels weird to have the power concentrated on just a few characters. 

      -Organizations doesn't look real. They don't look organized at all. They need to be more imposing than this. Their collective power should seem to be able to affect the story and not just be there as backgrounds of characters.

      -No division of plot. At this point it'll need a 1k chs to wrap this up and it'll be just one loong arc. At this point point there should be multiple conclusions but there's not. All the major things that happened at the start are still ongoing.

      -At the end, it seems like there's too much info withheld from the readers. There should be info-dumps at the beginning to create a solid outline of everything before reaching this kind of tension.

      I don't know but it seems most of these things are parts of the settimg. This may be weird but I think the author should consume more shounen anime/manga stuff. Like their setting, plot progression, organization, conflict, etc. Taking inspirations from them will probably make the novel more believable and concrete. 

      Disclaimer: No hate, only love. I still like this that's why I gave this a 4. And I only read things and haven't wrote a single page of a novel so this might came straight out of my ass.
