Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the sinister story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class—for the 13,118th time. She majestically announces to “break” him, without paying heed to anyone else around them.

This is but the start of a dark roller coaster ride that turns the two against themselves, the people around them and the one who may be god. Read on as their relationship slowly changes as they go against their most basic values in their struggle against the world itself.

If you could wish for anything, what would you wished for?

The premise of 'wish granting that turn into tragedy' is not something new. It has been used over and over again. What made Hakkomari different from the rest is, probably, the amount of 'concept' it absorbed and that most wish maker actually got what they are wishing for. There's no over the top malice from the being that grant wish. The theme of each volumes are:

First Volume: Groundhog days/repeating days.

... more>> Second volume: taking another's body.

Third and Fourth volume = battle royale.

Fifth and Sixth = revolution

Seventh volume: the closure that ties all loose end. I was kind of disappointed with the ending (I don't really support the main pairing), but overall, it's a nice read. Great character, all important character went through some changes and growth. Most importantly, all character finally find their "happiness" even when it's not the conventional type. <<less

Even the most innocent human have a its own weakness and darkness.
Yeah, that's the feel I get when I read this novel. IF, Remember IF you have a 'power' that can make your dream come true, what will you do? And remember, for your dream, you must get the consequences in exchange. It's either your loved one, your body, your feeling and many more.

Well, this is this novel's superiority in my opinion.
1. The Romance isn't something that grow in single night.
This LN's romance is growing up as... more>> the story line forward. From adoring to loving, it give you a step of loving someone. And he will sacrifice many things to protect his love. A thorny path of romance that require sacrifice to get. I LOVE IT.

2. Character Development
Character Development of Hakomari isn't just for MC and Heroine. It give a chance for other characters to grow in depth. It make this LN isn't bland and instead, give the color for this LN. Not only MC, but another characters too. I could even confidently said it, This LN isn't got just one MC, but instead, almost everyone of this novel is MC in their own right.

3. Decisive Execution
Well, this LN has a very decisive conclusion. Every single loose end is tied by author. Love this kind of novel that give you a decisive conclusion about characters.

4. Not-All-Happy-Story Type.
OK, this is a bit of rant for me. How the hell a MC get ALL things that he want to easily? Why he didn't get some problem that sheke him enough to despair? How the hell MC can do anything he want and anyone obey him? I.T'.S.U.N.R. EA.S.O.N.A.B.L.E!!!!!

Ehem, Well, I'm a sucker for Weak-to-strong MC, but not kind that trained and get strong or use nakama power to overcame everything. What I mean is His Mentality. His mentality is becoming stronger everytime problem come. And It doesn't mean he is becoming more stronger without sacrifice. He will be despairing over it. ANd he would jump and overcame. And this novel get that side. 5/5 Stars from me. <<less

One of the best light novels... And it is one of my all-time favorite novel that I have read. Some of you may think I’m over exaggerating but I can say with out most confidence that this is my all-time favorite...

Utsuro no hako is an occult story where our innocent protagonist finds himself stuck in a series of loops.

The plot is very well made. The characters are very well proportioned. And the back stories of the side characters are pretty well laid. The story is written in a... more>> journal-like description in the first volume. So, sometimes it goes to the 1st loop then time skip then goes 22nd loop.

It is very thrilling to read! <<less

The story and plot are interesting, but I've never hated a main character more then I did while reading this. I'm not saying the main character is poorly written or that the book series is bad. Just that every chapter I read I wished the main character would be killed off.

My rating of the story is based off my own enjoyment of the series. Not of the series itself.

I found the first arc and parts of the last arc to be quite exciting, but the middle portions to be extremely cheesy.

In particular, the MC (and some other characters) are textbook cases of Chuunibyou, first falling dramatically into despair (... repeatedly. It gets Real old), then making grand speeches about his own ideals, and somehow triumphing magnificently at the end by crushing the opponent one way or another (usually in a not-too-convincing manner, sadly). All this time, there's this creepy guy in the background that's absolutely obsessed over the... more>> MC, even when he's being a whiny kid. There's also this face-palming moment where the MC thinks how much better he'd have handled things instead of a another character, except he spent most of said event moping in self-pity.

Maria? A bland robot who needs some sense slapped into her.

Characters: 4/5 for the first arc, 2/5 for the rest because of regression and chuunibyou.
Mystery: 2/5. The mysteries in the series aren't particularly good. Half of the time the culprit is quite easy to guess, and even when you don't guess it, the answer doesn't feel particularly clever and is within guessable ranges.
Concept: 4/5. In the first arc in particular, the way the time loop is used is quite impressive, and the ensuing arcs at least gain points for originality and complexity of setup.

Overall, I rather wish I'd read the first arc and left it at that. <<less

My favourite LN so far. The description may not seem that appealing but trust me and just read it.

There are 5 different arcs and every ones of them link perfectly to each other. You might be wondering some questions but as the story progress, the questions are revealed one by one. Characters are unique and not your common LN troupes. Their backstory is well proportioned and they developed through the series and doesn't get "forgotten" by the author.
For example

... more>>

We got to know more about Daiya past. Then, we learn more about Aya Otonashi and "O". The conclusion is well made and leave us with an happy ever after kind of ending.

Man, that was pure ass.

The plot was alright, but the characters? You got a squadron of manic pixie dream girls who can't pass the Bechdel test, and a protagonist with so little personality, it's gotta be a ploy to allow readers to project themselves onto him.

Everyone tries so hard to be edgy, preaching some sort of philosophy while trying to sound profound but it just falls flat on its face. Like wow! Kazuki you're so quirky but deep with your obsession with every-day life!

*review regarding each arc ahead*
... more>>

Arc 1 (Vol 1) : This arc was pretty interesting. But I don't know why the author had to make it so that Maria repeats this timeline 27k times. Completely sobers up my suspension of disbelief because I doubt anyone can psychologically survive that, and could've got the point across by saying a more believable number that's at least under 3k or something.

Arc 2 (Vol 2) : Personally, I just found it so boring that I skimmed most of it so I can't say much.

Arc 3 (Vol 3-4) : I thought the idea of a death game here was so cool, but this whole time I'm wondering, is Maria ever going to give us more character complexity? Sure, she's a "box", her entire gimmick is to not have any human attachments except to Kazuki. But forreal? We're really rolling with an extremely beautiful human doll as a female protagonist instead of a girl with an actual personality? This story just screams it was written by a man. And I got another bone to pick with the depiction of Nana Yanagi, Kazuki's oh-so-beautifully-tragic first love. She clearly has some form of bpd or bipolar disorder, chronically self-harms and has manic episodes, and invested her whole being into her boyfriend, who she emotionally cheats on with Kazuki. And Kazuki just licks her tears off and is addicted to it? But then he blows up at her so she runs off with her boyfriend never to be heard from again, w/ the possible theory she killed him? That is so corny, I'm seriously wondering if the author's ever had a girlfriend.

Arc 4 (Vol 5-6) : So this was supposed to be the golden part of the whole story but idk, it was aight. Kazuki finally grows some back bone, but that's about it. I couldn't invest myself in Daiya/Kokone/Miyuki's backstory. Like if the whole point of the arc is to depict human trauma, then it should've done it more eloquently instead of a sequence of melodramatic scenes that rely on female infatuation with men. And I could not feel any empathy for Daiya who is a personification of the madonna-who*e complex based on how he either idolizes women he respect or dismisses the ones he doesn't as sluts. That, and he just came off as a Light Yagami wannabe.

Arc 5 (Vol 7) : I guess it's a nice resolution to everything. But again, my suspense of disbelief was killed by the expectation I should believe Kazuki relives the same day 400k times, commits mass genocide, then regains his sanity in only 3 years? And Nana Yanagi and her boyfriend just hops back all happily and re-integrates into their school life like nothing happened? Can anyone tell me what's one personality trait Mogi had other than a "sweet smile" and an obsession with Kazuki? Like I know this whole story was supposed to romanticize yandere romance, which I get, I love that sh*t too, but when the female characters are so flat it doesn't work. Kokone was the only character that felt complex to me.

Tldr; I am reading forum threads of people begging for anime adaptations of this series and bemoaning how this novel isn't popular in Japan in comparison to its oversea audiences, and that's just about the most satisfying thing I've gotten from reading this. I hope this novel dies in obscurity. <<less

First off Hats off to u author Eiji Mikage-sensei. I really did have a whole lot of fun reading this whole series. It was dark, it was thrilling, it was enlightening, it was really a piece which was an epiphany to me. The story moves forward in a way that ties up all the loose ends in a very satisfactory manner save for one or 2 points which aren't really points to be considered on a whole truly speaking. Humans truly are a mass of emotions as is depicted perfectly... more>> in this novel. Fueled by our egos we even deny that common sense of ours and justify our selfish/inhumane acts by spouting petty words such as justice, welfare, for the sake of the world etc etc.

I believe this novel was for the sake of enjoying a good time while broadening our horizons above our own petty views (at least I think so). Well I did have fun so I can justify my defense for this novel. A must-read!!! <<less

A story about wishes, desires, and boxes.

A "Box", an strange system that grants wishes, has appeared in possession of a certain person. Our protagonist Kazuki Hoshino meets a mysterious girl named Aya Otonashi, who asks him to help her find the person who activated the "Box". In a cyclic world where everyday is the same day, this pair must find the one in charge and take them down.

Volume one: Day repeats again and again. The story goes back and forth, telling things that happened before the story started in order... more>> to explain what is going on (not that it helps). Confusing.

Volume two: Body stealing... Very confusing if you focus on the details or the culprit's motive.

Volume three/four: The protagonists get caught in a deadly battle royale arcade video game. A simple story arc with a ominous ending.

Volume five: People start behaving like dogs because of some unknown phenomena. Megalomania at its finest. Revolution.

Volume six: The megalomaniac gets trapped in a cinema. Someone gets stabbed in order to stop the revolution. Novel's Title finally makes sense.

Volume seven: The darker version of volume one. Is there a better place to end everything than the place were it al started? Every missing information is given. Everyone is going crazy. Spoilers:

A dog is murdered!


Loved the ending. Enjoyed the story. Felt a desire to punch the author more than once. <<less

The story is incredible. There might be some parts that do not make sense, but the plot is 10/10. Characters' emotions and development are clear and interesting. Some mysteries of the stories are not perfect at some part of the story, but they are still thrilling for the readers.

Totally Recommend HakoMari

Yeah, like Shio said I also don't like the main pairing, but I also don't dislike it to the marrow of my bones, but I'd rather prefer the pair of Kazuki Hoshino and Kasumi Mogi that's all I want from this story= ((

Amazing series, my absolute favorite. I saw someone posting 'new' chapters, so I comment. This is already a completed series done by bakatsuki, it was later licensed so... bakatsuki took the translation down. I'm not sure if the person posting these is simply hosting or retranslating the series. Either way, it is fully translated and you could probably find a download somewhere online.

Again, amazing series! 11/10

To make sure we don't have a wrong impression, this is a romance light novel with a heavy emphasis on mystery. Not a mystery LN with a sprinkle of romance. With this, the overall goal of this work can be understood. Of course, there are other end points or lessons that can be learned.

Well, now that I look back. What made me feel attracted to this novel? Looking here, many reviews made me rediscover why I fell in love in this novel. Obviously from other reviews, there are also flaws... more>> that are true. Glaring flaws even. Let me say it in my own words.I love boy meets girl stories. It is my favourite type of plot. It is fun, but sometimes it's just boring, even unrealistic. Strange. How can you wish for a piece of fiction to bring you realism with this genre? Isn't the purpose of this type of stories the opposite, something that will never happen? A look back and I finally got it, a sense of realism produces this spark of life that makes me feel as if these stories happened somewhere in another world. A real experience. This novel managed to intertwine various genre that adds a breath of life to it. Of course, the novel sacrifice parts of its 'essence' in exchange for the change in direction, but this 'change' managed to entrance me in its story.

Ah, I'm sure you noticed or maybe I'm too self-conscious. My wordings present me as someone who is a little grown-up but is still too childish and idealistic (I don't deny it). This does reflect my taste in novels unfortunately. I'm often torn between web novels aimed at teenagers and another at adults. For teenagers, I actually quite like its wish fulfillment. What I don't like is it actively 'ignores' 'too much' aspects of life. For adults, it actively 'acknowledges' 'too much' parts of life and seems pessimistic or too pragmatic. I love 'both parts' of it but I don't want just the other only. It's hard to find a novel that manages to srike a balance between the two. Yet this novel indeed hit the spot on the mark.

Let me rephrase what I've read from a certain Amaz#n review.

My first impression of Kazuki Hoshino is your average jp MC who is indecisive about everything. A typical MC in your romcom or harem novel. He places an extreme importance on his "everyday life"as seen throughout the story. That is until a certain incident in which he meets someone... What I find fascinating is Kazuto Hoshino's decision to discard his "everyday life" to save someone that is important him. He disregard his peaceful life because that person had become a part of his life everyday life. To force through and change when faced with problems, even if some of his ways does not strike me as a proper way to solve problems, I find him admirable.

One thing I learn is that you will never be free of sins. But that is not the end. I believe you have to bear it and live through life until the end. while redeeming yourself of course. With that mindset, I started to enjoy flawed characters go through this journey and also just flawed characters. What made them become like this?How to fix their problem?What do I do to not repeat the same mistake? (Of course, I'll still dislike a character if his level realization does hit the coordinate I'm looking for, this is where that balance I'm talking about comes in) Before you say it, to apply it in real life is of course difficult.... I'm just a so called netizen philosophist....

I think that wraps up my thoughts for now. I didn't talk much about the story as other review have already expressed enough. I feel like this review is lackng just a little bit. Might edit in the near future if I remember it. I really feel the chuunibyo in this review.... whatever <<less

I've read and then re-read this series multiple times years ago. First, when only 4 volumes were released. Then, when only 5. Then, when only 6. I still have not re-read it for the last time, now that the whole story got completed. Because the latter few volumes are rather dark and emotionally hard-hitting. And because I don't want this story to end in my mind. I want it to stay incomplete. And I'm afraid that the ending would be bitter-sweet at best, but even more likely it would be... more>> tragic. I'd rather pretend that everything was solved in the end and that everyone achieved their happy end. Maybe, if one day it would be adapted into an anime, not just a general half-assed adaptation, but a masterpiece level adaptation, then I'll watch the anime. And maybe, just maybe, I'll complete this story in the end. And accept the true ending, whatever it is. But for now... This story will just continue to exist somewhere in my heart. Never completed. <<less

My very first Novel and I absolutely love it... Kazuki, he is the MC here but trust me he will give you show you different emotions from happiness to madness. The journey from the beginning (when Maria enters his daily life) to the ending (when it feels like everything is going apart), I loved every arc there. Except the 2 and 3rd novel. but later it got interesting.. and I really loved the last volume. An abnormal madness, just to protect his daily life.. just to save his daily life..... more>> wow.

Daily life? It really sounds too much interesting (atleast to me).

And it is my heartfelt wish for this novel to get an anime adaptation.

P.S don't mind my english here, because it sucks! Jut give it a try. <<less

One of the best supernatural horror/mystery novels out there. If you could wish for anything, what would it be?

This novel is in essence, a cautionary tale about the twisted outcomes that might happen when one isn't careful of what they're wishing for.

The plot of this novel, especially volume 1, was very well thought out and delivered in a manner which immediately drew the readers' attention. The characters were well developed and the writing itself was especially good. Definitely a novel that I would recommend for those looking for something that... more>> is a bit different to the other novels on NU. <<less

Disclaimer: I was searching for 'dark' novels, not mystery novels so personally feels like a 3 but I feel I should give at least a 4.
Was really hyped to read this after seeing the reviews. While the first few volumes were mind-blowingly interesting and I wouldn't hesitate recommending it with a 5/5 review. It just felt dragged out with same old mystery solving stuff by around halfway in and then things got weird in the final volume, as in weirder than usual. At the very least the conclusion wrapped... more>> things up nicely though. <<less
