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

Now that he enters his high school career, Satomi Koutaro begins his life living alone in an apartment that only costs him 5000 yen per month, an extremely cheap deal even for this small apartment. There’s a catch: the apartment is apparently haunted by a cute ghost that has driven its prior occupants away.

Next thing he knows, not only is there a ghost trying to drive him out of his new home, but magical girls and other unique female characters turn this small apartment into a battleground of sorts.

When I first started reading this I honestly thought this was going to be some generic Romantic School Comedy and nothing was going to happen each progressive novel. What made me keep on reading was the fact that we had girls from all over the place wanting to take over. We got aliens, mole people, ghosts and magical girls all aiming for the same room. I was like "Why the f**k do they want this room?" This is what hooked me in, the mystery that surrounds the room. As I... more>> keep reading all I got was more and more questions that surround the room and the main protagonist. All of sudden I invested a good portion of my time reading this series. Luckily for me, warren the translator was decently quick and did some quality translations. I had an inkling of what was happening but it was until volumes 7.5 and 8.5 did my eyes finally see what is going. And boy was it a glorious reveal. It made complete sense as to why they wanted the room and what each girls reasons as to why they stay there.

The MC

Satomi Koutaro is a somewhat funny character who likes to joke around with his peers. But when push comes to shove you can bet that he will be determined to what is right. In general we was a likable character to read and not some asshole. He can be dense but I think that's just who he is a character. He is not all that smart but he isn't naive. He knows when a character feels down and will make it personal to an extent. But until the big reveal I thought of him as normal and boy was I wrong in every aspect. And here's the thing, he knows they love him and he has his reasons for not being so close to them which is a major plus in my books. But boy oh Boy when you get past 7.5 and 8.5 he becomes a complete bad ass.

I rate this MC at a 4.5/5.



The Story

As stated before there is a lot of mysteries surrounding this story. Questions keep popping up to give readers a mild interest so they can look forward to it in the next novel because the Author does a good job at foreshadowing. Though my qualms about the story is the fighting parts of the story. The first arc is lack luster, not very detailed and nothing new but this novel isn't where the novel shines. It's about the interactions of the characters in the story. Everyone has a part and this is what makes the novel feel so whole. It's funny and cute with enough drama to keep you satisfied as a reader. Every novel will make you feel that its part of an even bigger story you have yet to see.

Only when we get the big reveals does the action pick up and become interesting. But because the story seems so happy that we don't get much on things that could pull on the heart strings. The one thing that I think it lacks would be those suspenseful moments. But the few we do have was enough to shed maybe a tear or so but nothing that would cause a river.

The story gets a 4/5 for executing the story pretty well but it could be better in some areas.



The Harem

Before the big reveal we get to see the characterization of each girl. All of them had undesirable attitudes which almost made me stop reading but as it progressed they started to become more and more likeable as characters. Each one of them are connected to characters in one way or another. They didn't just fall in love just out of no where but through interaction and realizing what they truly are under the facade they initially put up. The tropes they fill are obvious but they too also grow out those shells to be more characterized as individuals. They too know that the MC knows he likes them yet they don't push no it and wait because they know of the conflicts he is suffering right now. Until the day he is ready to face them will they be able to face one another. Though they do seem a little nonchalant about the fact that everyone likes the MC.

I rate this harem at a 4.5/5


Overall score should be around 4.5 but no option for that so its a 5.
Favorite Quotes: "From an endless time and a countless distance"
"Master, this ship, the Blue Knight, will pray for your fortune and glory in place of the nation of Forthorthe." (Spine tingles every time I read this)



The anime was okay even though it crunched about 4.5 volumes into 12 episodes. What made it so good was the pacing of the anime. It didn't feel so overly rushed nor did it feel like I missed to many details. But the anime is akin to a VERY DETAILED SUMMARY. It is definitely missing details that would have made a big impact on the story and the characterization of the characters. Even if you already watched the anime it is best if you read the series again to get a better understanding of what is going on.

I rate it a 3/5 watch it only if you want a feel of the story and decide if you want to watch it or not.

Don't let the synopsis and the premise fool you, it might like your typical Generic Harem Novel that has some To-Love Ru vibe. But in fact you might get disappointed, in a good way.

While it's true its a harem, but Kotarou isn't just your typical wimpy dense lucky pervert or conceited perverted kid. In fact there's not much fanservice in this novel. Its truly a Romance Comedy genre with the addition of Action as expected from a Shounen manga.

While its true the premise is ridiculous, but the Author created a... more>> really good explanation for the reason for the girls in each volume.

The MC also isn't two dimensional, he progressed and matured with each volume, it was a good character development. Don't let the cover fool you, this is not your typical Generic Harem Novel. The fast translation pace is also another plus as well <<less

Just gonna give a summary for each volumes in my OWN OPINION since the other reviews already covered what I wanted to say and to avoid repeating the other reviews.. this does not actually represent how good the story is as I have toned it down as to not give too much spoilers

Volume 1-7 - character introduction & overall prologue to the main storyline without reading the first 1-6 you cannot get the feel of the oncoming volumes or appreciate each of the character growth especially the MC

Volume 7.5 &... more>> 8.5 - just treat it like an OVA in animes though it has a good story so I wouldn't recommend missing it along with Shunkashuutou side story (like a recap episode)

Volume 8-13 - story with a good balance of action & slice of life, just don't expect too much on the action, there is progress in the main storyline

Volume 14 - volume dedicated for slice of life

Volume 15-16 - I guess this one focused more on action with less slice of life I guess its to balance with vol. 14

Volume 17 - another volume dedicated for slice of life, but this time focusing more on the conviction of the heroines, I guess this is to make the harem peaceful & to avoid having a bloodbath over the MC

Rating for: (?/5)
Satomi Koutarou (Male Lead) - I'd five 3.5-4 at vol.1-7 and 4-4.5 on vol. 8-17 with each volume his character growth makes him more badass but still having a likeable personality (rant: unlike SOME MC CN novels with harem where he doesn't treat women right or becomes too arrogant after becoming strong)

1st group of Harem starting volume 1-7 - (3.5-4.5 overall score) the main harem member as what I like to call it (includes the ghost, the two aliens, the underground girl, and the magical girl & knitting girl) with each volumes you will really see how each member grows especially the Theia & Yurika


2nd group of Harem starting volume 7.5-17 - (4.5 overall score) the next group of harem with an addition of another magical & alien girl and the landlord.. though enemy at first except for the landlord obviously, each member has a likeable personality and good story to tell so even though they started out late they are as likeable as the first group or even better.


Antagonist - (3.5-4.5) - in my opinion the early antagonist is somewhat 'lukewarm' they do not really give you the feeling of a last boss, if I had to give an example it would be like a boss in the early level only to find out that its a common enemy in mid-level.. then the antagonist starting 7.5-12 it would be 'warm' the antagonist started to become better.. then vol. 13-17, they are now starting to look more shounen antagonists, who said that only the protagonist can grow?

rant: unlike Team R*ck*t, the antagonist after losing also started to grow on their own way... I even like Maya & Elexis


Plot -
Volume 1-7 - I'd give it a (3-3.5) not bad but also not the best story at the beginning, you'd even wonder where the story will go

Volume 7.5-12 - (3.5-4) after the introductory volumes I could finally get a glimpse of where the story would go, though the problem is the direction is as many as the heroines + maybe a harem route?

Volume 13-17 - (4) I'm 95% sure we will have a harem ending by the end of the series <<less

At first when I read volume 1, I thought to myself "Great, this is another boring novel". But when I read volumes 3-5, it gets pretty interesting as the plot started moving forward after volume 2. I legit read all 18 volumes, 5 days straight! With food + drinks!

Now the plot and if you don't want to spoil yourself, do not click the spoiler:
... more>>

v1-2 is the introduction of all the main characters arc and the start of the plot
v3-7 is the 'Blue Knight Play, Yurika's 'identity', as well as Kiriha's first love arc
v7.5 and 8.5 is the 'Past' Forthorthe and the Legend of the 'Blue Knight' arc (read volume 7 first as you would be confused if you skip volume 7.5 and 8.5 should you directly read v8. it's pretty good imo).
v8 (yes its in that order 7.5>8.5>8) introduces another main character, Maki
v9 Ruth's fiancee and the invasion of the Rebel army of forthorthe (this is where we know of forthorthe kingdom's situation and Satomi's 'badassness'.)
v10 Travelling back to the present and Kiriha's 'secret' (This is during Past Forthorthe arc and I was actually blown away when I read this as I was like "eh, no way.. that's her?!")
v11 Sanae and her 'still alive' body (This is about Sanae and it's pretty amazing imho. This also introduces a certain 'being' in which you saw in 7.5... which you will see in future volumes, HYPE)
v12 Yurika's role being revealed 'again' and the invasion of Darkness Rainbow (Harumi's power is revealed and you will be in for a surprise~)

Next is where the plot starts moving forward along with Satomi's feelings of the girls and what he's trying to change inside. He's not dense, it's something regarding the past that he can't accept the feelings of the girls 'yet' (if you read v10). This is also where Harumi figured out the Satomi 'that's distant towards others' and why he's in the knitting club.

v13 The second coming of the Blue Knight and the Truth that's revealed to Theia (This is the epic part of this novel.. read it then you will know what I mean~ Also Harumi is now a harem member)
v14 Shizuka's 'mass' (lol) and the events of Forthorthe 20 years ago (You will understand why it was 20 years ago if you read volume 8. Satomi mentions about keeping 'it' a secret).
v15 The Beginning of the Radical Faction's Invasion part 1
v16 End of the Radical Faction's Invasion and Kiriha's 'Invasion' part 2 (This is where we first start seeing the power of the Demonic energy that's being granted to Tayuma and the 'black' hole)
v17 Everyday Life
v18 Yurika's determination, Nana's start of revival and the foreshadowing of Folsaria, the Magical Kingdom
v19 To Folsaria; Darkness Rainbow vs. Rainbow Heart, and the Rise of the Magical Girl, 'Rainbow Nana' (Tried to make the title badass but she's f**king back!! Also, If you still haven't gotten the meaning behind the name Folsaria, then you will know in this volume... probably).


I seriously recommend this, and for those that read past v1-2, props to you because you will see that you would want to know more about the story when the plot progresses forward and you will keep reading it till you won't even realize it.

Each novel focuses on one character for that novel as it's relevant towards the plot.

And you will know how I feel afterwards~ <<less

This story is AWESOME in every sense of the word. Harem? Yeah, but the most illicit romance up-to-date is a kiss. And even if you're a harem hater, this should not bother you. Character depth and development is outstanding.


Watch out for time paradox feels after volume 7


Defenetly a must read for all those romance and shounen fans out there. One tip:
Get someone with a crowbar by your side for if you need to get going soon, because you will not be able to stop reading if started. Enjoy!

After reading v22:
The author keeps on continuing the story while keeping the connection to v7.5 and v8.5 strong. It's a very well packaged story. Repeatedly I question whether the author did plan every detail for the rest of thee stories when he wrote 7.5 and 8.5. Compared to my other favorite novels such as To Aru Majutsu no Index series, Kyousen Horizon and the series, and Hyouketsu Kyoukai no Eden, this series has its own unmistakable charm and definitely is another of my favorite.


Up to v14:

I'm surprised there's quite... more>> a number of people who likes this novel. I found this novel through the anime (which is interesting but pales in comparison to the novel in terms of delivery, but detail is good), and ignored it for like 12 volumes until I started. It reminds me of Index - where the author throws random 'short' stories only to reveal it's all connected.

This story is also connected like webs. When you think you figured out what the puzzle/connection is, the author later reveal there's an additional connection. Then you start to realize the little details have their roles. I shiver at times due to how well the connection are revealed. The connections aren't 'critical' to the story but it adds a layer of meaning to the existing stories. And I did cry after reading v7.5/8.5, especially while figuring out how it connects to the previous stories.

The author gives a lot of single-line foreshadowing which can be easily ignored, but you have to remember that there's a reason the author put them.

Also actually the author injects a lot of genres, so this is one of those fantasy stories which mishmash a lot of ideas together. The delivery may not be as liked by some, but I appreciate how the author meld them together.

Like.. Outer space mecha fight in the later volumes.. Wut..

One of my top novel read, at one glance this looks like your daily slice of life harem, well you are not wrong, but this is delivered so good you wont regret reading it. As the story goes on, turns out the plot is better than I ever expected, even including time travel, and dragon! Every girls written good, even the most pitiful magical girl can make you smiling inside and watch her warmly.

10 volumes (ongoing) of no regret.

One of the reasons I registered here is to give this a review. This is definitely my #1 favorite novel.

First of all, anyone reading this book should first survive until the end of seventh volume. Everything until then is just a prologue.

This book is a perfect harem, despite keeping things platonic. But that doesn't mean it lacks in anything else. The story is great, the characters feel alive and are all interesting (even those like Yurika, who initially feel annoying). Even antagonists... there are two kinds of them in this... more>> book. Expendable ones, which noone cares about. And recurring ones, which are almost as interesting as protagonist party. But all in all, this story has everything. Magic, politics, science, space combat... and feels. Lots and lots of feels. And it doesn't mean it's slacking on any of those, they're all interesting and well-written.

The only thing that worries me a bit is that author doesn't seem to be entirely sure what he has in mind for them yet. Regardless, I don't think any of the characters will be left out. Unlike the usual, protagonist has earned his harem. And he's so reliable that I'd entrust my daughter (if I had any) to him without a second thought, even knowing that she'd be like 10th wife at most. <<less

Best Japanese LN I've ever read and the fact that it's a harem doesn't detract from the quality of the story. I usually hate harems but this novel gives all nine girls proper character development and introduced them all really early in the story unlike others that introduce a new girl each volume only to forget about them when the next one comes. Highly recommend you read this.

This story was pretty entertaining. It had surprisingly good romance although it was quite slow-paced when it comes to that. And although it does not have an action tag it has a decent amount. The story isn’t about battles or powering up, it’s about the relationships between him and his friends/potential romantic interests.

This is yet another of my "didn't grab me" novel reviews. I tried to give this novel benefit of the doubt. Lots of people gave it good reviews. But as of the end of the first book I was sitting there going "sure, it's occasionally funny... but would I be reading this if not for the reviews?" And my answer was "No, not really." So I dropped it.

Normally, this wouldn't warrant a review, but I saw that the only reviews were 5 star, so I figured it would be good... more>> to throw in my opinion so that people don't have unrealistically high expectations, like I did.

It could have a great plot later on, and maybe the characters get better. But the first book was cookie cutter harem romantic comedy with nothing new and cardboard cutout single aspect characters, and it had no plot whatsoever.

I like harem, but the first book would be an example of "harem done wrong". It introduces all the girls in about 1 chapter each, and throws them at eachother. 5 girls in 8 chapters. It doesn't allow enough time to learn to like or care about them, and it doesn't give the author enough time to even have a plot in the first book.

All in all, it just came off as generic and stale. Maybe it gets better. But I can't recommend anything that I didn't find interesting. <<less

Light slice of life, lighthearted comedy, and action for the later parts. This story changes as it goes, explaining things and placing them within the storyline to fit in. Each book adds more to every character (although sometimes one book one character) and the series has a certain feeling of warmth to it to keep you thinking about each character and their situations. Another addition is that this series actually sticks with the apartment through the whole series while relating new locations (and of course, new characters) with it to... more>> never get you bored of the scenery.

If you don't like how characters are portrayed, wait a couple of books, because more details will be added for reasons of personality, history, ect. <<less

A very entertaining LN! The plot is well written and will leave you with a lot of questions which will get answered later on. This isn't your typical harem series where everything is predictable and corny. It's true it starts off a bit typical (if you leave out how weird the girl's are) but as it goes on the author display their storytelling skills with good like foreshadowing. The harem is also very unique: there isn't a single normal person in it and that's what makes it fun. Everyone can... more>> fight so no annoying damsel in distress. Although they all have problems they can't solve on their own, but they gladly help each other out so it's all good.

My favorite harem members are:

I love all of them but these five are my fav


Story: 5/5
MC: 5/5
Harem: 5/5
Characters 5/5

It may not be perfect as they would have less trouble if they actually kill some of their enemies but you really can't complain since the enemies are tolerable. <<less

Rating: 4.5

Reason for a half point taking off is the one problem I have with the story. To much of the exposition by the author is repeating things we already know. Instead of letting the reader infer the reason the characters are acting like X its spelled out for us. Doing so for things that happened books ago would make sense, but things that happened a chapter ago do not. Its unnecessary and bloats the story.

Its more of a problem I have with all Japanese works since its a common... more>> trope among all Light Novels. That doesn't excuse it though.

As for the rest of the story.

The harem in this is probably the best done one of any Light Novel harems out there. All the girls have a reason for wanting to be with the main character and the main character has a reason for not advancing a romance with any of them. The cast of characters are all flawed with their own back story and motivations. The romance isn't their raison d'être like in most stories. Rather a byproduct of circumstance.

To get more in depth with how the harem aspects works in the later novels would spoiler a large part of what this series is. At first glance you see a fluff story about a group of strangers fighting over a pointless thing. By normal standards its nothing of noteworthy to mention. It would be forgotten or thought of as a nice read when there is nothing else to pass time with. Yet that's not the case.

Without spoiling to much there is a shift in story telling that takes place a few novels in. Once it happens you realize the series has more depth and layers then what you can see at first glance. In that regard this series is definitely an outlier amongst its Light Novel brothern. Each story builds on the last and each one gets better. <<less

Not going to give review since the one below already give GJ review for this. One thing for sure is:
-don't avoid this novel because harem (the harem is the one element that make this story good)
-don't rant if MC act dense (he have proper reason why he act like that)
-don't be fooled by first impression (some of you at first might be dislike some of the character but they growth and they chara become more better)

I don't know why someone will rate this only... more>> 1 star (only one person thought) well every person have they own taste <<less

This is one of my favourite novels due mostly too how light hearted it is.

The romance is pretty good but its slow and the main character is a bit dense like usual in JP novels.

It has its fair share of action but its mostly about the interaction and the growing relationship between the people living in room 106.

Its a fun light hearted story also pretty intriguing.

If you like slice of life and romance I am sure you will enjoy this novel

So frankly I love this ln. I love the characters. I love the story. My only problem with it on as a whole in somewhat predictable and not enough pictures :) and both those points are fairly manageable. I will agree with everyone else on the story really picks up in 7.5 and 8.5. They answer a look of questions and are some of my favorite volumes. I also like even the side characters aren't ever fully forgotten like the cosclub sometimes makes an appearance here and there even tho... more>> they have little to no impact on the story.

5 Star! This is my first review.

I'm really enjoying this series. The characters are funny, there is action, sci-fi, magic, paranormal, well there are too many girls and sometimes it feels cliché but the banters are good that I find myself continue reading.

At first I felt like the author forces so many roles to the MC too much but by the end of v7, everything connects. But it got hyped good when it got me thinking 'so the author written this for this purpose', 'so thats why that character said... more>> this'. Author is genius! If not, he must spent time thinking and planning this from the very beginning.

Edit. After the hero side story arc, character development feels so forced to me. Very cringy. Dropped it. How do I change my rating? I want to rate it 3 star now. <<less
