Kurei Yukito made a wish on the verge of dying. In his next life, he would like to become someone who can understand other people.

However, the next time Yukito woke up, he had been reincarnated to a different world in the midst of war. Moreover, he was granted a cheat skill as a result of misunderstanding his last wish.

He was picked up by the rebel Prince, worked as the go-between of messengers from other countries and did his best to talk to them despite his poor social skills. Yukito desperately lived in this different world in order to accomplish his dying wish.


In this world where wars are common, hints of war gradually crept up to Yukito…

The start is really weird. The MC is sent to another world and meets a noble. Suddenly the MC is swearing eternal loyalty to the guy he just met and becomes his advisory. It is really weird for the MC to suddenly be a nobleman's adviser, and even weirder he is so freaking loyal to a person he just met. The author just ignored any realism with this and just forced the story. Which is not a pleasant reading experience.

I am not sure what to think right now. The relationships and kingdoms are alright. But, there are a lot of unanswered questions, and the author seems to just skip and suddenly all the relationships are progressed, the prince appoints the MC as adviser for no reason and so on. First mini-arc is focused on maiden and her dilemmas and the smooth talking MC makes it all better. The second mini-arc is the prince wants to overthrow the king to protect his sister, the sister:princess also hates the king, she... more>> became an enemy. But now due to their positions the prince and the princess are waging war against each other, and by the look of things the victor will be the prince and most probably the they will come to a compromise and clear everything and all will be well. But, I simply cannot stand that, they simply throwing away the lives of the soldiers because of their pettiness, the people besides the ones the author elaborates on hold no value. I simply cannot stand that, and because of that I hate the characters. And using people like fodder for character building is something I simply refuse to accept. Its a matter of principle. Also, I quite sick of 16 and 17 year old's everywhere (both females are around the same age and both are super OP apparently and super famous, and then there is one more minor female around the same age).

Also, if you want a novel that's well written, characters make logical sense, mature in its execution and people's lives are not fodder read: Rakuin no Monshou

Edit: I was a bit harsh, and the entirety of this review is my subjective feelings. Unless you are of similar mentality, go ahead and give it a try. So don't let my words discourage you, give it a read. You may like it more than I. <<less

Being the current translator (as of 220516), so I might be biased in my review. So just take it with a pinch of salt. It's a not so much of an action-based other-world-teleportation novel. Yep, you have war, but your character uses his brain more and information that he can acquire (his cheat basically.) Actions will be mainly on his partners than him. Next, the web novel doesn't clarifies most of the gaps in between the stories but only in the LN, which I do not plan to translate as... more>> I don't see why I should start doing something when I am already having trouble keeping up with the main web novel. I don't usually dig too deep into the story, so I have no problems with this too.
Another thing, this is without doubt a harem tag, so those people who dislikes them, yeah please refrain too.

Other than that, you should like this story. I mean it's one of the few story where your usual char is a non-combat personnel but he still gets the girls. So Yeah! That's enough to get a 5 out of 5 for me. <<less

The protagonist loves to read history books, a loner, and is killed (stabby stabby stab in the kokoro) by his best friend for some unknown reason. He dies and wished to have the ability to understand people more in his next life. Miraculously, he is safely transported to another world with the almighty appraisal skill. A rebel prince found him and accepts him as his aide just after a few seconds in the novel without having known his personal background nor his abilities, just for plot's sake. He is then made a strategist just because he managed to befriend an OP mahou bishoujo from a neighboring country. He then confronts the spineless bishoujo commander of the enemy army which also happens to be the rebel prince's sister who's father wants to f**k her so badly but instead of resisting, she even wants to capture her brother who wants to help her. I cannot fathom any briliant strategy orchestrated by the MC, I can't even call what he does as strategy. Everything just seems so wrong... Maybe the title should've just been "the MC knows stuff"...

This is a really good novel to read especially for those who likes smart MC which utilized his head rather than brute force.
Spoiler for kids:

1. Don't read it if you see missing details regarding relationship or whatnot.
2. If you dissatisfied with those details, go ahead and write a story yourself.

The story is a bit progressed which skip the relationship between the MC and his lord, also why did he swore loyalty to him, why did he reincarnated and for what purposed, also suddenly we see our MC in a civil war sided with the rebellion Prince - only chapters will tell.

Regarding the story I have read, the lord or his retainers saved him thus he returned the favor by serving the lord. This is somehow understandable but lots people don't have brain.


The hyped of this story is that our MC always entangle with danger situation and find solution in those time while his combat capability is very low - untrained, no combat cheat - and his only ability is in analysis which put the right people at the right spot and time, utilizing their potential to the utmost.

I gave this novel 5 stars caused of good story telling, quick pace progressing, fun conservation among characters, and mostly the anticipating of further chapters.

I recommended this novel for everyone who want a good smart MC, strategy theme, and war related topic.

Usually, I don't make reviews when I barely read just 3 chapters, but I couldn't stop myself from writing this.

There are 2 reasons for my 1star review.

1. Skipping over any of the minor stuff: basically all of a sudden this magic girl (some woman that's amazingly beautiful incomparable to any woman on Earth apparently) is in the castle and she is basically one of the most powerful people on the continent... and the MC is just chilling with her alone.

2. wtf is the logic???: nothing makes sense that's going on,... more>> like this one line from the MC

After acquiring permission, I take a deep breath. Seeing those wind bullets, what I am about to do is most likely su*cide. She was also trying to tell me that the next one would hit, having missed her first shot. Even so, I still wish to release her from her anxiety.

... why? Like the MC doesn't have any encounter with her before this conversation (btw they barely even started having a conversation) so why is he risking his life just so he can 'release' her from her anxiety?

Maybe this is pretty minor, but it's annoying to me since it shows that the author isn't making an attempt to make things seem real (logical) instead of going with the thought process of

"It happens because it just does" <<less

Listen, ignore all of the reviews that say stuff like "Why does the prince immediately trust this random guy" and "why is sister princess even on the kings side?" because those issues are sorted out by the end of volume 1. And for anyone angry about deaths of thousands of people being treated lightly, make sure to read all the way through volume 2.

This series is a good bit of strategy, entertaining writing and an MC who is interesting to follow. Highly recommended.

It might be to early to judge, but I'd just state my opinion for now.


You found a guy laying in front of your door or anywhere, you helped him and gave him water/food. BUT would you let him roam around your home? And let him entertain your let's say... Boss' daughter? Without knowing his full background? And only talking to him for a few hours at best?

... more>>

ME: HECK NO. You're insane if you'd do that. I don't want to lose my job or my life.

Prince in the story: YES, because I'm SO KIND! I'm not sure why I'm still alive and haven't been assassinated but I would still accept him by my side. And maybe let him talk with some important guest I mean why not? It's not like he might kill her or something right?

I understand that the MC want to repay his debt of him being saved, but I don't understand how the heck can the Prince trust someone who is half dead on the street? What if it's an act?

I don't like how the author shoved the MC to a good position just to progress with the story. A single day can't make you so close to someone of high position. He should have took his time to build up some trust between the two characters. And why would a prince let a stranger entertain some high nobel of another country which can cause a conflict if something goes wrong? So basically the prince can either be a complete idiot or have some powerful divine clairvoyance, other than that the author just don't know how to start the story. I would have preferred it if the prince summoned him or something like that at least there is some connection but even then there should still be some trust building not just some random shoving of character.

Also I honestly don't know if the problem is with the author or the translation. For example:


When Sophia said "You... are really gentle." then he suddenly introduce himself. I was like "WTF?" so basically the pause for "You..." means she was hesitating to state his name or something?.


What the heck is wrong with this nobles? How trusting can they be?


A prince who trusted a stray guy, just because he have black hair and black eyes. The author needs to work with this stuff, where is the building of trust? He is a prince, why would he pick up a guy who might be an assassin?

As for Sophia what the heck as well.. she is so easy to open up. I mean I don't think a psychologist can make someone open up that fast. She's a noble and a strong one at that, she breaks that easily because of kindness and gentleness there is a limit to how close to breaking point she is.

The worse part is this happened in a SINGLE DAY.

2 idiotic nobles actually believed a stray guy who have no background whatsoever and TRUSTED HIM.

As of chapter 6, the story is still building up, but it is interesting. The MC's cheat is more like a having high charisma points, because I still have not read the MC using a lot of strategy. It would be nice if there were more than two updates a month, but beggars can not be choosers.

This light novel is quite old, so maybe this review no longer matters, but I'll write it anyway.

I found the novel interesting, so I read it in the original Japanese. I have reached chapter four and enjoyed it so far.

I felt surprised to see the rating on Novel Update so low, so I checked the translated works. People have worked hard to translate it into English; however, I found the translation very lacking: it was hard to read, and there were clear mistakes (if my knowledge of Japanese is correct,... more>> some words are translated with wrong connotations and/or meanings).

Due to these mistakes, people might have mistaken impression of the story progression, leading to the complaints about the logic of the plot. It's understandable. I will not blame the translators, though. They did it for us to read for FREE.

Still, I will rate this based on what you will get if you read the English translation, so ONE STAR.

But if you can read Japanese, I recommend it. <<less
