Chaotic Evil Villainess novels are generally fun for the first couple of chapters then quickly peter out, so when the initial rush wears off there is a temptation to check out.

Stick with this one. After the end of the first major arc I will admit that there are 8-12 chapters (all short and around 40 or so, whenever it is she goes underwater) where it looks like things are starting to lag, but trust me, if you like the genre, if you make it through this patch, the ride from... more>> then just keeps getting better.

Chaos hasn't been this much fun since Elric. <<less

This an extremely good story. At first I thought it would be funny, and have an interesting world. This goes above and beyond my initial expectations. It goes deep in to the mc's motivations.

... more>>

In the chapter 79, it starts to show why the MC is like this. Here father neglected her and thought of her as a murderer ever since her mother died, and she feels extremely aggravated seeing people getting the affection she wanted but couldn't get.


On top of all that, the MC is a badass with amazing technical skill <<less

TL;DR: Not for the faint-hearted, doesn't have cute moments, takes a bit to get used to the random violence and reading the story in between, but it's enjoyable overall and has quite a bit of future potential. The translation is also pretty good.


A story about a psychopath who isn't specifically designed to be more likable. She doesn't reflect the psychopathic side of the thoughts of regular people (like people coming up with plans to murder someone without actually doing it) but rather is a pure psychopath with literally zero empathy;... more>> she doesn't even understand the concept.

She's brutally toying with actual people (i.e. Torturing and injuring them) just to see what happens and has eventually stopped doing so in reality due to being told, not because she understands the reason, and now she's found a release in this VRMMORPG.

She doesn't talk that much, so most of the early chapters don't allow for a deeper view into her character and she seems pretty flat, but the most recent chapters at the time of writing this review start to show the first signs of depth and character development.

The game itself is the standard unrealistic one where players entirely dive into a game world that for some reason has incredibly high realism (especially in regards to violence) and even supposedly transmits pain. Supposedly the highest setting (which the MC chooses) can also affect you in real life if a vital organ is destroyed. This doesn't ever come up again however. There are tons of unnecessarily detailed skills and it seems foolish to even try to keep track of them because of how fast the MC requires them. The important ones will come up in the story anyway, the rest is just bloating the status.

Lastly, concerning the society of players in the game: I vaguely understand that they would be opposed to killing friendly NPCs that don't respawn (again, who would make a game like this?), but I just don't understand the emotional attitude towards more or less instantly respawning players being killed in a game that has PvP enabled as a clear part of its design. Again, unlike what was mentioned before, nobody is said to have died from it in real life, and even if they did, it would have been their fault for having their pain setting at maximum (I mean it would technically be the fault of the provider of the game, but that is where one has to suspend their disbelief). People running around in PvP games indiscriminately killing literally everyone they see including NPCs is absolutely not a rare phenomenon in reality, but for some reason her attitude of doing it rather than her skill of being able to do it is what other players focus on (they do mention her skill, but in reality it would be the only thing anyone cares about, not the actual act of killing other players in a PvP game). <<less

Not gonna bother with a full review, but instead just gonna give a little warning.

This story is not for people who're unable to enjoy a VRMMO story with a game that would never work in real life. If you're unable to ignore the unrealistic parts of the game in the story, don't bother with this one. This story is probably not for you unless you're able to ignore that and just enjoy reading about an overpowered girl going on a killing spree in a game.

I like this novel very much. MC is a unique character. MC is clever on her own way. MC understand herself she is very strange (physically and mentally). MC seems life as a play ground like pumping water to ant nest and make people to chewing insects. MC seems this world different way. The only person who can help to her to control herself is her mother and her father hate her didn't care about her but she didn't know reason. One day MC saw her mother apologising to teacher... more>> for her playing. After that at school MC didn't play at school. She like to be lonely and quiet that help to her control her psychopathic side and act as a refined lady. After her mother death MC thinks she cannot control psychopathic side so decide to show her psychopathic side at game. <<less

Very fun and huge points for uniqueness. Although definitely, some people might find it too over the top. Out of hundreds of novels I've read, I'm not aware of anything remotely similar. Basically the WN version of someone messing around in grand theft auto.

its a great novel, only part I don't like is her fight with her siblings bc that is some grade A power of friendship bullsh*t

... more>>

i f*cking refuse to believe that her siblings can somehow match against her in just one day of playing, before you say that they killed high level players and speed leveled, our MC have been killing thousands of npcs and players, quite alot of high leveled people too, also they don't have the same level of skill our MC has, its literally their first time playing and fighting people, no way in hell will they be able to put up an even match against her, who solo entire armies, top ranked parties and players, but they somehow managed, MC skills magically got reduced by 80% in their presence for some bullsh*t reason


otherwise great novel <<less

well, what can I say? This whole game element is simply nonsense. Truly broken and cant be accepted. Is that how mass pvp based game works? Honestly the world building is 0. Minus even. MC isnt "likeable" at all even factoring many other MC with cold and ruthless personality.

Good novel if you like a MC OP and who kill almost everything that moves when rampage. But really, there is level and skill but MC dont care about it. She is super OP even when she is level 1 and she use daggers like pro and can throw them accurately even if its her first time with them. And nope, dont tell me that having a skill level 1 for dagger use and throwing make you skilled like god.

Let's all be honest in here, there's no way that a MMORPG where the NPCs do not respawn would have any living NPCs left in the first town within the first few hours after being launched, or any NPCs at all within the first few days. What bugs me more in this series is not the fact that she's just going around insta-killing everyone despite beign lvl 1, it's the inconcievable idea that there would even be people left for her to kill in a game like that at all.... more>> The author simply ignores the existence of the trolls that make up a significant part of the players in any given multiplayer game. I signed up to read about a sadistic sociopath torturing and killing women and children and using clever schemes to get away with it, not to read about an internet troll PKing in a VRMMORPG. <<less

Oh my... Such a refreshingly twisted MC, not manipulative just pure sadistic joy. <3

Sure OP from the beginning is unrealistic and I would have preferred more buildup but it makes you get to the slaughter faster at least.

Damnnn I love this novel so much, I'm surprised I'm only now giving a review. The main character is interesting and her actions are both unexpected and sometimes hilarious. Expect a lot of action like a sh*t ton. Throw ethics and morals out of the window while you're at it because she massacres everyone. Young, old, man, woman, good, and bad. In general she just do whatever her heart desires and that mostly relies on whether that something is fun/interesting. She's both cute and terrifying cuz her common sense is... more>> a lil off.

The plot is entertaining and makes me wanna binge read it (which I did). Her growth particularly on her social side is always a joy to read because of the way she interacts with them. Going from an impossible person to approach to having people to call her friends is pretty heartwarming. Both her game life and real life are fun to read. All in all this is a 10 for me. I never get bored reading and re reading this <<less

This is kinda fun in the beginning but devolves quickly. There's no proper world building and the MC has no personality.

The PvP system doesn't work the way like it is shown in the novel. The game mechanics are basically broken.

It was pretty fun to read at first, but the story get's pretty repetitious as it goes on. Any resemblance or inclination of a plot starts on chapter 48. The story kind of just proceeds on and reuses the same formula it did 10 chapters ago. Protagonist meet's new people, kick's their ass, repeat. I guess it does change up the pace a bit my introducing the protagonist's life outside the game at around chapter 65, but other than that, not much else stands out in the story after the... more>> first 20 chapters. <<less

If you're looking for a masterpiece, this aint the place. However I had a ton of fun reading and anyone that likes power fantasy or psychopaths will have a blast with this It's a good book but if you're a critic then you wont like this. There are many huge inconsistencies with the novel including how the heck the main character and nobody else is OP despite some people even getting a decently sized head start but if you live for power fantasy this is a good story. Both translaters... more>> have done a really good job with their work. Anyways, enough of my rant go read this if you're a power fantasy addict and find something else if you aren't. <<less

You know Kumamiko? The endless fluff novel, everybody seems to talk about? This is that, but the oppisate. Raw, fun violence.

Ever read Max Vitality and think, "hey what if they actually deserved the developer's reactions?" This is that.

This novel is the tar for when you're overly full on fluff.
