Honestly, this is one of the most consistent character portrayals I've ever read in a light novel! You can clearly see that the MC's previous life dictates the way she lives her reincarnated life. Usually reincarnation novels have a more tepid, back-and- forth characterization. Something like: "minna-san, s*avery is bad, okay? Let's take common knowledge from my previous life and change this world to be more like Japan nee~~. What? Polygamy?! You mean I can have 6 wives?!!!! Huh? What previous life? Japan who?"

And it's just so irritating to... more>> see a promising story/MC downgraded so the author can force along the story/deliver pointless fan-service. But this novel doesn't do that at all. The characters drive the plot and not vice versa. So the emotions are much more palpable and the situation feels so much more realistic (though still insane).

Curse this tiny tablet of mine, giving it 1 star when I meant to give 5! <<less

This novel is seriously painful to read... in a good way. Basically a girl reincarnate into the villain of a fantasy novel and decide to willingly walk through the villain route knowing it would lead to her destruction... all for the sake of her beloved Onii-sama. There is no comedy, no reverse harem, no light-hearted misunderstanding.

It's full blown heart-wrenching fest that would make you wish the MC would be just a little bit more selfish. If you're looking for a novel that would claw at your heart and makes... more>> you cry, this is it. <<less

Wow... what can I say about reading this series... Reincarnation is my favourite genre in LNs and wow this series was like a breath of fresh air.

Ok, the general blurb of this series is about a girl who died not by accident (truck-sama was busy) but she was sick. Her original life was centred in a hospital who can only dream about having a normal life- in her final moments, she wished to live like the MC of her favourite Novel. When she reincarnates, she realises she became the... more>> little sister of MC who was the main antagonist of her beloved novel.

Unlike most LNs that have the genre of Reincarnation or 'I-got-reincarnated-into-a-game-must-avoid-destruction-flags!' the MC of this series does the complete opposite. She welcomes the destruction flags this was because of her love (admiration) for the MC. I love how she's so easily understandable- you know her reason for doing things; this was the biggest driver for me to read this series.

Sadly, it seems that this amazing series was dropped or is on-hold. I hope a translator will pick this series up! <<less

I'll mention Death Flag Shows No Signs of Ending cz it's so popular and have similar premise where the MC were forced to be the villain. The difference is this one is darker and unlike death flag where everything still went nicely, everything in here is bleaker, things always end up wrong. Knowing that she's a sickly girl that died too young before reincarnated makes this even more hurtful to read. Her insistance to destroy her own self is just sad. And the author is smart for making me feels... more>> like there're hope and crush it with even greater sad reality.

Give this a try. If it feels too absurd, remember the fact that she's still a child and keep on reading for reasons justifying her actions. It's heartwrenching and addicting. There're depths in characters and inner monologue. It's not your typical easygoing JP isekai reincarnated. Keep on reading it, become my brother in arms, let's get depressed together. <<less

I read the machine translation and guess what? Horrible!!! The MC who was given a second chance due to her strong wish with literally everything-power, authority, money, wasting her second chance for her brother whom she doen't even know much about apart from the novel, and what's with the plot?! If she wanted she could have created a kingdom for magicians with much authority, but she want to follow a novel plot she read, not taking her second life seiously. The MC is blessed with invincible power but she wastes... more>> it by not training after defeating her father.

the MC is burned to death alive leaving behind a child under her brother's care

This is s*upidly good so far. It's not the typical fluffy, cliche ridden experience one normally gets with the 'reincarnation into a fantasy world' trope. Character development actually happens!! Characters are developed and there are reasons behind characters behaving villainous. The story kind of feels like a more serious Avatar:TLAB. Also, the translation quality is fantastic.

I consider this story as one of the best novels I have read till now,

The first 3 volumes (chapters) are great in my opinion, the MC tries to help her brother on her own way and although the story may seem small it was surprisingly consistent. The plot was good (for the first 3 volumes) and the characters are consistent with novel. Till the third volume the novel was entertaining overall.

for the first 3 volumes the story deserved 4.5, but I have my reservations toward the last volume.

... more>>

Although I did not read it because the translations stopped but I read spoilers from the forum about the ending and it was exaggeratedly dark. I do not know if the author has reservations toward incest or something but the MC SHOULD HAVE ENDED WITH HER BROTHER THE ONE SHE LOVED IN THE FIRST PLACE, instead, her vessel broke and she could not use magic anymore and she ran with Atlas from the country and her brother became the king or something and they had a daughter, adding to the dark element of the story she died a horrible death smiling (burned) in front of her daughter because the magicians were being hunted down by the people because the people saw them as inhuman beings. This kind of ending because either the author against incest or he wanted the end to be heartbreaking, but whatever the reason the ending seems to be forced to the novel, so I am disappointed from the novel because of the last volume and it affected my whole experience by just remembering it.


so at the end, if you do not want a lingering bad taste on your mouth just read the first 3 volumes. <<less

A story of a re-incarnated girl that wants to live a meaningful life, and does so by following the villain route of an otome-ish game she knew in her past life. This is all in order to help her favorite character, the brother of her re-incarnated self.

A heart-wrenching story of self-sacrifice of the re-incarnated girl and her choices, actions, and thoughts. She does it because she believes that it's still a game that she can change with her foreknowledge. Yet is readily becomes apparent that she can't and... more>> she furiously struggles against that fate.

This is done through chapters and parts of chapter that cover segments of her life. It allows for the reader to see the consequences of the choices she makes quickly, and makes you INTENSELY wish she survives through the end. Hopefully she does, but given the tags on this series, not likely. <<less

This is an inevitable tragedy.

It is the direct opposite to the other LN Death Flag Showing No Signs of Ending in which the male lead tries his very best to change his fate of death.

Here, our MC does all she could to make sure that she will become the villain that will eventually be killed by her brother on his journey to save the Kingdom.

Some people are questioning her motive here, but I don't find it hard to understand at all. The complex she has is quite similar to Lelouch's... more>> in Code Geass, as both characters love their sibling so much that they are willing to die a villain.

Moreover, her persistence in being the villain is not only for making her brother a hero, but also to protect him along with the rest of her fellow mages in an extremely unfavorable era to them.


She was born in an era in which mages are dying out. The world was moving in a direction that discards magic and turn to technological development. You could say the MC was the last prodigy of magic that represents the old time that worship magic. Therefore, she is targeted by forces inside and outside the Kingdom. So far, our MC is well known as the princess of inferno on the peak of magic; hence she can single-handely ensure mages' social status. As you can see, her mere existence is intolerable to the new world that is about be born. If she falls, which is expected by her many enemies, then the rest of the magician society will collapse, including her brother that is yet to make a name for himself. Therefore, our MC has to stay strong and kill many until her brother can grow into the destined hero.


It looks like the previous translator has dropped it (or it could be that they caught up, I am just speculating here based on the date of update). However, it recently has been picked up by another translator and so far the story, in my opinion, has yet to come to its peak.

Edit: it is already concluded in raw.

Origa has a daughter with Atlas. They changed names and appearance and live somewhere else. Her brother, Gil, eventually built a kingdom that uses a barrier to separate mages' society from the common society. You could say the story has a happy ending. HOWEVER, the epilogue tells from their daughter's pov that Origa, the MC, is burned to death smiling in a witch hunt ten years later.


The only down side for this story is that the time skip is a bit too much. I don't know if it is the translation, but I feel like sometimes all pieces of information are jumbled together in a few chapters that cover a huge time gap. It does cause a little confusion for me, but it does not affect its overall quality. <<less

There's a girl. She reincarnated after she died. She, who died because of illness, thought how she cannot make anybody happy. So, after been reincarnated, she wanted to give a happiness to a person that she know would get hardships in future..... even if it means her destruction.
That's the premise of this story. Well, it's an antihero protag that use every thing she have to save her beloved person from dark experience. 'It doesn't matter if I become villain... 'she said. Her supposedly ideal ideology become crooked midway, because... more>> of some experience and conviction that she must do. So, prepare your heart. This story isn't about wish fulfillment, instead it's all about hardships and despair. <<less

Reading this story left my emotions in disarray. It's a twist to the usual reincarnation to an atome game. The MC reincarnated as the villainess who is the sister of the Protagonist of the game she reincarnated to. Coincidently her brother - the protagonist of the game - is also her favorite character, so after reincarnating her goal was to help her brother. However that made her mistreat him and cause a bad impression of herself. With that, angst and drama happen. T__ T

It's heart-wrenching yet addicting. Unfortunately, the... more>> updates are slow and irregular. Definitely Five-star <<less

I'm reading up to ch.4 and skipped straight to the ending/prologue. What's with this heart wrenching narratives and dialogues? I'll edit this when I'm more coherent, but... I totally didn't expect my emotion to be this mess. So many things I don't understand because my lack of Japanese comprehension skill, but I'm determined to read the chapters in between when I have time.

I'm mixed honestly. At one point the emotional side kicks in and it's very heartwarming and gut wrenching all at once. But I can't help to think that all the mc's problems would be solved if she wasn't acting like a dumb*ss.

... more>>

If she stopped to think maybe, she could have found an easier and more effective ways to save the beloved protagonist without screwing herself over. Although it explains the want of her destruction, I still don't get it at all. It seriously makes no sense to me because it just sounds like she's doing it because that's what her role is supposed to be. But logically speaking no one wants to die and if she questioned the good of playing the villain role in the off chance it helps her brother develop, then why couldn't she stop to think to play a good person?


It seriously is s*upid, but well written and tugs the heart strings in a weird way as well. <<less

Love it! Frequently we see rebirth/reincarnation used as a crutch. (Is it really necessary to make a female MC from the 21st century so that she can be believably strong in a historical setting? Can a guy not think outside the box magically if he doesn't have high school physics and chemistry?)

In this case, not only is the rebirth intrinsic to the story, but the MC encounters actual *conflict* and *anguish* as she has to continually stay true to her villainess role. And then there's what happens... more>> when things don't go according to plan! I feel like I can see traces of the epic fantasy novel the original MC fell in love with as she's drowning in the tragedy of her new circumstances, from playing the role of a monster to living it, and I wonder how she will react as her original beloved story is warped beyond recognition.

Oh squee! <<less

My review may or may not change the further I progress especially since we're only 3 (long) chapters in. Furthermore, it's best recommended if you skim through my review if you want to dive into this without any hints of spoilers. As of 1/5/17, I've upped it to 5 stars.

Reincarnation has been a trending theme for the past few years, and this novel manages to get something that's been so often repeated and turn it into an enjoyable read. It's like seeing character tropes and seemingly generic characters written well,... more>> except this applies to the plot. The writing and translations are especially good, and the story moves at a very likable pace- neither too fast nor too slow.

The characters are, as far as I can see, likable from a writing point of view. The 'villains' of the first few chapters are written in a way that makes you dislike them in the way they're meant to be seen as a contrast to the villains I often find myself disliking because there's nothing to them. The heroine has a brothers complex that isn't cute-fied and the story is surprisingly dark with plenty hints of internal political and social class drama (which I have a long standing affection for.) There are references to her knowledge and the change-the-future! (For the better) trope which happens in nearly all reincarnation novels- whether the MC intends to change things or not- isn't occurring here. EDIT: In the recent chapters, it's apparent that there are now too many changes. If I had to chose between better and worse then it'd be the latter. Now that there are more important characters introduced, it's easier to picture the world as well as the twisted characters' relations to one another.

And yet, you can't help but wish this will end happily. The author seems to have a way with words that suggest some things may have change but make it just obscure enough for readers to be unsure of the future events. I personally think it won't, but I'm putting my bets on a satisfying ending, happy or not. All in all, definitely try it out when or if you have the time. <<less

Just two words.

Code Geass.

Had the same effect as this novel. To make me cry very uglily. There are just some anti-hero novels that I just can't help but read it even if I know that I will just end up in a sad puddle of my own salty tears.

It's amazing how the author wrote it in a steady tragic way. You can't even see a single ray of a happy end. It starts of with a neutral leaning on happy vibe then it just gets more and more depressing as the story progresses.

For those who came here looking for a generic reincarnated into otome game plot (coz honestly I chanced upon this when I was looking for said stories), you might as well steel your heart before reading this.

This is a novel that is not really fun to read... It will force you to embrace masochism. The MC's life is so tragic and heartbreaking because she's basically throwing herself (and this novel's readers) to a bottomless abyss of despair. The only thing motivating me to continue reading this story is that glimpse of romance between her and the ML (not really sure, but I assume the guy with wood magic is the main lead).

Plot-wise it's good, but really challenging to the heart. You'll surely need many bags of... more>> tissue. <<less

After reading the reviews, I was so surprised by how much it's being praised because I know a lot of good and bad web novels that are being bashed. This is probably the only web novel that has tons of praises in the top reviews.

One thing though, just from the premise and the comments of the people, I doubt my heart could take in the story of this novel, I could already feel the cracks just from staring at chapter 1 (mind you I'm still not reading it). That's why... more>> even though it seems I have found a very good novel after a long time, I have to passed on this one.
