In another world called Aletia, the boy who had saved the Lost Kingdom, conquered their neighbouring countries, and led to the rise of a grand empire decided to throw everything away, returning to the modern era at the cost of his memories.

As three years passed, the boy who was happily enjoying his daily life was once again called back to the other world.

I really like this novel. It fulfills all my fantasies and wild imagination thought it might be a little bit childish but that's fine. I don't want the translator to drop this novel, the light novel version in english has not come out yet.

Hope that the translation of this novel continues

Looking good so far, the characters are fleshed-out even more so for the MC. I'm a sucker for schemes, psychological battles, and war-type novels, and the author executed all of them really well.

The MC's past is still a mystery as to what happened because there are some bits of monologue that hints the dark and tragic events that lead to the MC being who he is. Hiro will not hesitate to kill anyone if they get in his way even if they're high ranking in the hierarchy... more>>

Hell he will even kill a duchess if he needed to and the duchess is the main love interest's sister


The plot is interesting too since we are slowly learning more and more about the MC, whilst simultaneously reading about the perspective of the side characters and the antagonists. The antagonists have their own realistic reasons for declaring war, not just battling for the heck of it. Each of the sids characters are unique in their own way

I need more interactions between Altius and our boy Hiro


Please note that the novel is not for the faint of heart, it is a serious novel without much comedy. This focuses on the lives of generals, commanders, and other leaders and strategies used in war, and I'm warning you, it gets bloody. The romance is there but it isn't shown much at all because most of the time, the characters (including the MC) are either currently in war, or interacting with other characters and scheming behind the scenes. Also translation is very good

Edit: it has come to my attention that someone reviewed the MC as "dense", or "beta" without even reading 3 volumes at least. These types of reviews infuriate me the most; they're like Journalists, they don't finish even 3 volumes of the novel to see who the MC becomes. 5 volumes in, the protagonist isn't dense nor is he a "beta" where did he even get that assumption from? Please read the first 3 volumes of this novel then review because these volumes are what shapes the MC and turns him into the badass we know <<less

I can't. I just can't. Why do all these Japanese author have to take out the practicality and reasoning out of the equation??

... more>>

The princess sleeps with a random stranger (who is our mc) the very first night they meet. She hugs him to sleep and no one in the army thinks that it's weird. She changes her clothes in front of him as if he is air.

But there is this one guy who keeps on complaining whenever he meets the MC and sees him with the princess for no reason.

prince wants to go against the emperor and murder his 6th daughter despite knowing that once it's done he will be executed... the reason he wants to kill is cos he is afraid that the princess might become the successor to the throne.

Children barely 15 years old are given important positions in army and they are portrayed as the most prefect beings in existence.

King orders to execute all the ministers cos he was loosing the war...

This is full of such dumb logic... I don't know what goes through he author's mind when he uses these kind of logic....

dumb writing.

Should I have read more chapters before commenting ?

Maybe.... but I can't read a novel where the starting itself is flawed and illogical.... maybe I am being biased but this sh*t is not for me.

Novel is probably one of the better jp Isekai novels. This isn't really a harem nor a romance. Romance is more of a subplot if anything. The focus would be between the redhead and MC. So far enemies faced have their own agendas and reasoning for what they do. Characters have their own personalities.

MC is op in military strategy and ability. There hasn't been any real difficulty for the MC, opponents move to his plan every volume. But it was enjoyable to read. He's not dense and is aware of... more>> his surroundings but he focuses on his objective rather than the women around him. He does not spare his enemies unless they can be useful pawns and doesn't shy away from killing then either. <<less

The first chapter really hooked me and I kept reading. (this was back in 2017)

At first I read the web novel version but after it got discontinued I started over the light novel.

The war aspects are fun to read and the time difference between the MC's first time being sent to the world and going back 1000 years later is interesting as I'm wondering how the time axis works between them.

... more>> There are some flaws which can be overlooked and it doesn't really detract from the story.

It is one of the more sensible isekai as the MC has killed in wars in the first time he was transferred to the world and he is not a f*cking dumbass. He's actually a sensible leader.

The war and strategies are really fun to read and is highly entertaining. The side characters as well don't feel completely bland. I think this series has a lot of potential.

I'm just waiting when the people will find out that MC is the War God Emperor himself lololol.

Overall 3.9 stars

Edit on 1 Dec 2021: well I read the final chapter of volume 6 and sh*t just got real man. Man this is so cool. I don't care whatever someone says Hiro is f*cking cool. The ending of vol 6 made me totally enjoy this story and now my rating is a solid 4.3 stars ✨

I started vol 7 immediately cause I couldn't wait and now the plot thickens and I NEED to know wtf actually happened in MC's backstory man. I need the deets. (If someone has read the entire LN series spoil me in the dm's) (I need the info man...)

There are definitely some flaws but man author really managed to reel me in through MC's sheer mystery and badassary.

I really loved this novel. This novel is one of best in war genres I have ever read filled with schemes and Conspiracies, constant cool fighting scenes with overpowered MC having a high IQ for detecting potential threats and scheming. In short reason, I really love this novel is because here though MC is Hero, he doesn't hesitate to "Kill" unlike our most of Japenese light Novels where our MC is goody two shoes who can't kill being born in peace filled world which irritates me to no end as... more>> how is it possible to live in a world of constant killing from Monsters and Bandits without loosing people or killing back at all? I mean it obviously sounds s*upid right? So my friends this novel here is an extremely realistic fantasy setting according to me as it allows you to feel anxiety, pain, love and sadness all these raw emotions hit you like a storm since it is a novel where your life is constantly on edge as again this is a proper "War Novel."It also employs lots of war strategies and tactics and makes an effort to sound MC's overpowered strength and intelligence reasonable. Although as usual, our MC being overpowered will overcome through all these hurdles a little more easily than acceptable.

This novel also belongs to genre where MC has tragic past which is overshadowed for a long time (till now I mean, it is not brought in open to other characters) and he is fighting that pain alone but is slowly getting filled by love of main female lead and other people around. Although this is a Harem novel, till now MC's strong bond has been shown with only one main female lead and other 3-4 potential Harem members seem to have appeared but frankly overall romance has been on a little weak side till now especially with other potential Harem members. I hope it will get better in this aspect. As for female main lead and others, they have their unique personalities which are very attractive With some being innocent, other scheming, ruthless or brave warrior and ofcourse one being our openly seducing girl which is quite fun to watch. So female characters are all fleshed really well till now and hope in future all of them will give us a proper picture of Harem romance. In other words, it can be said it has been a slow burn turn till now. But here thankfully, female characters have not been shown all as idiots throwing themselves at MC's foot and atleast author is attempting to form slowly closer bond with some girls. <<less

This is one of the few good Japanese Novels out there. The MC is not dense, not trying to turn this world in to Japan, he has the mentality of a warrior not a Japanese like other JP novels (I mean killing is not allowed in Japan so I will not do it in this world sort of sh*t)...

give it a try atleast wait till the MC recovers his memory then you will see how awesome this novel is.

I don't agree with the author the characters he like I don't like. The MC's plan is dumb and really the world is full of unlikable characters. The author doesn't want the MC to be the typical black hair character who is the focus unfortunately I found the other characters boring.

Dense, Beta MC. Thus 2 stars. These types of MCs make me f*cking squirm in disgust.

However, lore, plot, girls, are decent for a read with lunch and tea. Would recommend if one can handle beta pieces of shit. Thankfully he isn't always like that. Yes I know it's early on. It's still disgusting.

This one is to you Antithetic.

At first, I thought this would be a amnesia novel like those old animes where protag remembers his past and power only when he's in trouble and then forgets it afterwards. But as soon as I reached the end of the first volume. I was speechless. The Protags behaviour did a 180. I was hooked.

I know he acts like a Beta in the first volume. But it's only limited till the chapter 4. His behaviour does a total 180 and stays that way.

Antithetic, I highly... more>> encourage you to read the volume 1 atleast. I also thought it was boring and was almost giving it up. But I was surprised.

Novel is very real. And incidents that happen have a real depth to them.


There was once a situation where someone wrote on a parchment but didn't roll it up immediately because it wasn't dry


The attention to detail given is outstanding. Though it doesn't compare to legendary works like GOT or the Witcher.

But this is definitely the best realistic "light novel" I have ever read.

(Yes, it's not the realist hero)
