Previous Life was Sword Emperor. This Life is Trash Prince.


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

Once upon a time, there was a swordsman who wielded the sword, lived by the sword, and died by the sword.

After days and months of battle, the swordsman chose death by his own free will, but was reborn as Fay Hanse Diestburg, the third prince of the kingdom of Diestburg.

Wanting to distance himself from his past life where he lived as if possessed by the sword, Fay decided to just lead a life of a wastrel, earning the nickname: “tr*sh Prince”.

However, one day, because of a pact with the neighboring kingdom’s Afillis royal house, Fay is sent to war, leading reinforcement troops. On the battlefield, Fay witnesses a scene of despair, as the “Hero”, an existence possessing power rivaling tens of thousands, ravaged the battlefield.

Fay considered returning to the kingdom, but a certain knight’s death manages to shake his heart, thus he decided to wield the sword once again — the legend of the strongest lazy prince begins!

This is unreal. How come such a garbage of a light novel got 4.5? I ve made an account at 5:00 am just because of this story. I ve been reading this reincarnation genre for 4 years and I ve read every book about reincarnation in this website but holy $%#@ was it difficult to read this one

First of all, make no mistake I know what this "kind" of novel tries to do usually. It presents an MC who was the best at this or that in his world. He... more>> reincarnates in this or that world and starts flexing his power while trying to hide it. Thi is the important part cause it pushes the reader to recognize himself in the character or I d say to recognize himself in the " normal " side of the MC. I call this kind of novel a self-masturbation novel. It s my guilty pleasure, I know and I ain t gonna lie. This kind of novel doesn t need to be a master piece you can ignore its flaws but it has one job and it s to immerse you in the story but... this garbage of an author can t even do this one thing right. Come on man you had one job.

1. The MC is realllllllllly the embodiment of the word edgy. You know there is a fine line between being cool and just freaking edge lord. Try to guess in which category this MC falls. He starts off being interesting, but he ends up acting like a teenager with a chuunibyou syndrome. I ended up skiping some parts while reading cause I just can t believe the sh*t he is spitting

After saving the kingdom he is allied with, the princess asks him how to get as strong as him and guess what he says? "Do you want to become a beast like me"... I mean for real man why can t you give a normal answer. The best part is how he died in his forner life. Apparently he reached the top in swordmanship and guess what happened? Did he die of old age or all the martial artists go after gis life. Nope, He freaking killed himself cause yeah loneliness. He was killed by his own edginess


2. The story is way too rushed. And makes no sense. The MC goes from not wanting to interefere in the war to participating to wondering why he took part in that war.

he says he wants to lead a peaceful life and taking the sword will lead him to death and be held down by his desire to get stronger (f***** cringe, right ?) but guess what ? 3 chapters later, he meets someone who is dying on the battlefield. he decides to fight cause he wanna die with a smile in his face like that guy...2 chapters later he is like why did I fight that war...


3. The characters don t have a personnality. Seems like their thinking process is that of a 6 years old and they are only there to help the MC to be more cringy than he already is. Not gonna lie the moment I think the MC can t be more cringy, there comes a character to help him to reach another level of cringe.

I can keep going on and on but I gotta sleep. Just don t read this story please have some respect for yourself and your time

If you wanna read something go
read solo leveling, second comimg of gluttony or the novel s extra. Any of these is was better than this shitty story. <<less

Some novel best read as a whole volume than a chapter, this also applies to this novel. I don't agree with the top reviewer by the name Canadabererut, maybe he can't see the potential of this novel, he only read for 4 years after all. Firstly most of his review shows how lacking his perception of the novel's character and the plot is. He doesn't know the meaning of the plot and how it varies to bring good storytelling. Let me tell you something first, this is not a web... more>> novel like Solo Leveling or Novel Extra, its a light novel, so it should be more than a normal web novel. What that means is this novel has an editor who makes sure the plot, the character, even the interaction is good and not a waste of time. And if everyone keeps saying edgy this edgy that I just don't understand how edgy are you? You need to show how unedgy you are by saying this is so edgy and shit, I mean is that some kind of hating a mental person? Because the character is definitely a mental person, so by saying thing like "this is so edgy" is so amateurish, and show how much lack of knowledge you have. Basically Canadabererut is saying "you are edgy" to a mental patient, try imagining that. A lot of critical acclaim literature based on a mental person, and this also true for this novel, so always saying edgy shows how low your literature knowledge is.

This is the plot of the novel (for now)


As shown in the synopsis the MC is a sword emperor who is very strong, his mind is scarred because of his previous life so he chooses to become tr*sh. But he is a prince and forced by situation he must show his power once again. The only motivation of MC is to protect, he doesn't want to kill or even carry a sword, he hate the sword. But the sword is his lifelong partner, his only way to protect someone, so he always using it. Because of the Afillis's war, his power become known, he somehow minimizes his popularity by making a treaty that Afillis should not tell anyone of what happened. But we can safely assume almost every high ranking people in the world know his power (as he kill thousands of people).
The protagonist is not some kind of crazy maniac killing hero, or even a hero at all, no, he is a normal human. He is brave but cowardly, as he kills to protect, but scared of losing. He is strong but weak, as he may be the strongest hero but never overcome his mental burden of killing. Ultimately he is a kind person who forced by the situation becoming what he should not be.

The plot goes around his story and how he got forced to face battle after battle because while he is tr*sh, he also a human, he can't abandon his humanity. He doesn't want to fight, but only by fighting and killing, he can save those around him. Cliche but a strong plot if go right.


Below is the real review of the novel, not the bias plot of some kid who doesn't understand a story.


The story focused on a mental person who is the MC, he is a person who lives in the previous life as a sword emperor. The MC is a kind person, but become a mass-murdering beast because forced by the situation. His previous world looks life the sengoku era or warring era as shown how everybody around MC died even though they are strong. MC basically forced to kill to live, even though he didn't want it, he is talented in swordsmanship, and in killings. This scarred the MC's mind and heart, he becomes mental or crazy, because of that sometimes he can't do things rationally and changing his decision by heart.

We should not think the MC as a rational, great, supreme hero like the normal protagonist in JP story, but as a mental person with disturbed mind who does things irrationally. He changes his mind quickly like a kid, but sometimes he shows a great commitment like an adult, this show of attitude can only be explained by the MC's disturbed mind because remember he is not a logical person, he is mental!

As the story focused on the MC, many character show a lack of development (for now), maybe in the future it will show more, but for now, it doesn't, and that's OK because many great novels don't show every one of its characters, you just need the protagonist. While this may seem a downside, but the all the characters show a high degree of logical and sound mind. They have goal, they have personality (albeit little showed), and doesn't act like a s*upid puppet.

For now, I see a lot of potential of this novel, hence the 5 stars, the MC show a complex but also simple mindset and action supported by the relevant world-building and plot. There is no such thing as tr*sh writing like mob-villain who bullied/tr*sh talk the MC like most novel, there is no power trip of showing power just for the sake of showing strength like in the most novel, and there is no s*upid character interaction like the most novel, and that shows good writing!

The only downside of the story may be how the plot goes, as many good novels out there, protagonists who show so much character and story tend to gradually become stale and lack of development. And seeing how the story goes, MC's only way to show development is by interacting with other characters. This usually starts great but end s*upid, either too absurd, too simple, too over the top, or too cliche. Because of that, I pray for the author's talent in writing. Because this kind of story will lose its focus the longer the story goes, if this light novel have 10 volumes then it will be stale and maybe become shit. So maybe I will update the stories as it goes.

This is one of the edgiest novels I have ever read. It's a teenage edgelord's wet dream.

Every single dialogue, the main character will force the words "I'm tr*sh" in it. Usually in other novels, we learn through various other characters or actions that yea this guy is tr*sh, but here? The author just shoves it in our face, he just tells and tells and tells without much showing it.

To me, it seems like the author doesn't know how to introduce a character's settings to the audience. We just know too... more>> much too early about the MC. It doesn't keep you wanting to know more about the MC, instead it leaves you wanting to skip parts about the MC's inner thinking because it is all the same thing repeated again and again.

This novel probably will not get any better without some serious improvements in the writing <<less

Story seems interesting but MC really irritate me with his constant 'tr*sh prince' dialogue. We get it already. You have no ambition. Don't need to say it every few sentence like it's a prayer. Is almost like he is a ret*rd that has to keep saying it. He keep telling others that he doesn't mind what they think of him or how much they badmouth him. Just shut up already. If you really don't care what others think then stop saying it so obvious like you are begging for some... more>> pity.

Plus this MC is contradicting himself constantly with every action he took. First he say he don't care then suddenly he seems to care. Make up your damn mind already. <<less

"Previous Life was Sword Emperor. This Life is tr*sh Prince" resembles quite well with "The Lazy Swordmaster".

I would be reviewing it based on genres first because I couldn't feel the novel that well, to do it exactly.
    • Action: It is not action biased story from what I have currently read. The action scenes are just passable and I don't feel like it being ameliorated anytime soon. And I couldn't estimate MC's current prowess at all because he keeps underestimating himself while thrashing his opponents into hell like a cold-blooded being (it could be because the story isn't purely based on fighting I think).
    • Psychological: I am quite dissatisfied with the author's approach to this one. The author keeps changing his writing style in both a good and bad way. The story keeps getting unsynchronized due to this.
    • Comedy: There are quite a bit of funny moments here and there that can make you laugh although a few. But it may be another selling point of the novel.
    • Characters (being an exception as it is not a genre) : The characters are likable, just the right amount you need in this kind of story and I don't think character development is being focused on much though.
The story being mainly dark isn't as uncomfortable as you would feel it at the start. The potential was not used as it should have been, as I said earlier that the story doesn't pour out necessary feelings. The MC being unambitious known as 'tr*sh Prince' was a good idea but again the necessary elements just couldn't feel quite right. The flow of the novel has been good knowing the author's approach to the story to not make it boring for us readers. I sincerely hope, it turns good after a few more chapters otherwise its doom is inevitable.

In the end, I wanna say that the Translations and content quality have been great for the most part.

Honestly it's a great story about a reincarnated man regaining his humanity. Definitely one of the best "underestimated protagonist" stories I've read, as the MC has a genuine reason (past trauma) not to use his strength. The writing itself is quite smooth and all his interactions with various side characters are also enjoyable to read, there's no real romance as of yet and no nonsense about the MC building an unwanted harem, which is always a good thing.

just give it a try. It is worthy of your time. The author really knows how to create a proper MC with past and present. He knows how to create a proper character with the mindset that he was created with. This world is created properly and the story progress properly and even the side characters have personality unlike most novel being some random for the MC to go on along the storyline

Waiting for his meeting with the hero to really give a proper rating. But I gotta say, it's the first one in a while that I have high expectations of. The pacing might seem slow for some people but I don't mind it. The description is misleading (or I have trouble reading), the scene of despair has no impact on him picking up the sword again

Edit: This novel is quite something else.

The world building is interesting. Battle mostly revolved around "Heroes", extremely powerful existences that can literally kill armies by... more>> themselves. So far it seem like most of them are drunk with power and act just like barbaric mercenaries. I highly doubt there will be any genius display of strategy but more of the intense 1 v 1 scenario. Which is fine for me but some might not like it. Come to the core of this novel, the protagonist. This guy, from what I've read, represent the feel of the novel. He's an edgy, emo protagonist. But not like the all the other isekai, revenge, emo, my life is bad, I'll kill everyone emo cause they hit my knee once. He has quite a clear reason for how he act and why he act that way.


He wants to die while smiling. Quite comical but the story does a good job explaining it.


His mind and value is twisted, as it should be given his past and circumstances. But not to an inhuman degree like many other that lead them to forgot about common sense. He is still human, albeit a bit insane. Is he relatable? Not really, but you can see and understand his action. Is he a walking contradiction and a hypocrite? Maybe? But who doesn't, it's quite humanlike to believe in something then does something opposite to it cause you have feelings. Is there romance in this novel? It's hinted but not explored.


basically yes, but not confirmed


Normally I hate multiple POV cause a lot of authors just use it to retold stories you already read. But this novel actually did it correctly for once and give you interesting view on our protagonist. Right now the side characters are limited to name, profession and thoughts about the protagonist but the potential is there. I just hope that the author pay attention to the big hole that is "too many side characters you don't care about" when writing. Especially since this novel has quite a slow pacing, meaning that for a lot of the novel, it will be about the side character (and their interactions with the protagonist). About the actual plot of the novel. There is none currently. There is no foreseeable ending for the novel except the protagonist wishes. It would not be false to put this novel under slice of life. And that is not a bad thing, the protagonist and the way the author tell his story is interesting enough for me not to mind it. <<less

Wtf this is good. It's pretty deep even if the MC is annoying. It got me curious about the backstory/past. The past life is interesting and shrouded in mystery, especially his mentor who's apparently the only one who could kill him. MC was apparently weak and there were others who were strong that protected him. I'm thinking he only became the strongest because everyone else died.

Edgy or not, what I see is a depressed broken man who literally killed himself. The only fault about the MC was his humane heart... more>> which is a "weakness" especially in the previous world where only the strong survived. His mental state is still very unstable though. Still, at least he's not naive and got things done, thanks to his experiences. <<less

So far so cool. MC is totally bonkers but his craziness is... logical? I mean, readers can understand how and why he is like this. In previous life he went too far in the path of sword. He laughs as crazy when he kills, but in the end, it's just an act that he learned to cover his weakness and then it's just became a very unsettling habit. MC basically Wuxia Sword Emperor in Fantasy world. This world totally not ready for him, but... imagine if somebody like Chu Yang... more>> was summoned as Sword Hero in Rise of the Shied Hero, it feels both right and wrong at the same time, in result giving somethat exotic feel.

Despite being japanese light novel it's not very light with how thousands of humans already died. If not his shenanigans with elf maid, I will say that it's feels more like good chinese novel than japanese one.

Also, there is "Lazy Swordsmaster" in "recomendation" list, but MC here isn't such an unresponsible ass, no he just have different value set. More akin to tr*sh of Counts family, althought I don't think there is going to be as much lying to himself. With a bit of Chu Yang from Transcending the Nine Heavens, or whatever is the name of protagonist from Human Emperor.

It's a bit too early for final judgement, but so far I have a high expectation for this story. <<less

The other reviews ring true. This is a really good read and the flow of the story is so smooth that it would make you beg for more. I really want to know what's next and I'm excited to know what the MC would do after.

Sadly, not much chapter is available for reading so I will patiently wait until the next chapters have piled up for me to continue reading.

It's a story that you can say as "worth the wait" (atleast based on the current chapters, that's what I can... more>> say). <<less

Absolutely beautiful, I always look forward to the new chapter of this story because it is just that damn good!

I like the potential romance, but even if that doesn't come into fruition it is still a nice little subplot.

His past life is very mysterious and cool with a heavy tie to his current one due to what he saw what wielding a sword meant. This is one great MC and probably will be a badass one (I think he is badass even before his fighting).

I can see that this novel... more>> has a monstrous amount of potential and am hyped to see what comes up next. <<less

The underlying story is somewhat interesting but the author needs to grow up a little.

This novel has a legendary level of suicidal angst. I mean every chapter is dripping with the MC's self loathing, over and over and over again. But unfortunately, the sentiment is one dimensional. It has zero subtly or depth beyond what the first few chapters had established, but continues to consume 70% of the word count in almost every chapter. It quickly becomes repetitive and overbearing. I guarantee there's nothing out there right now that can... more>> reach this MC's level of melancholy, even in modern anime. But at some point, the author needs to get on with whatever actual plot he's trying to get to. I'm afraid by then, I will have lost all interest in reading. <<less

MC had a good reason to hide his strength more than just avoiding attention. MC is a reincarnated person who had been through plenty battles and bloodshed. Added with flashbacks, it makes a complex character that you want to root/care for.

A downside is that the MC is just too self-deprecating. I'm the tr*sh-prince over and over. In his inner monologue and dialogue. I half get it, he didn't want anybody to have expectations on him, but he says it all the time that it almost comes out attention seeking and... more>> disingenuous.

No harem or any romance (as of now). I don't know if the LN marketplace is just satiated with harems or I just reading a lot of it. It felt like a fresh breathe of air that there's a japanese isekai LN when girls are not flocking, hearts in their eyes over the MC. This gave the opposite effect where I hoped the MC finds a love interest.

As of now, I rated highly. <<less

I really enjoy this series. The translation is great, as well as the pacing, which makes it even more enjoyable. All the characters I've seen so far seem reasonable in their actions and thought processes.

But the thing that I enjoy most are the sad undertones. I love how his past life actually affects his personality and character, making him the way he is now.

On the website, I saw some comments on how they think that the story is rushed, or the characters seem to trusting of MC being strong and... more>> other such things, but I think that's because they don't show much of his life before. I mean, he could have given small hints or something about his real power? <<less

Nice story with some fresh plot.

Dropping because of monologues and because human can't change from cold blooded murderer to classic Jap MC. If you train simply good martial arts for a year your thinking process will change a bit. MC spend his live while killing and now he is a lazy guy? That's pathetic
