In the mix of stories that have impacted me so deeply I feel they have instantly affected my perspective on the world, Misumisou is kind of a unique one. And because of a very ordinary reason, actually. It's short.
And so, it has made an interesting decision to not analyze its themes and instead focus on portraying them in the most gut-wrenching way, which I feel results in an almost eye-opening experience.
This essay could wind up being longer than the manga as even my notes for it are already 2.1k words long, which is a funny thought.

Also, as a personal note, this is the first review I've prepared for, so I hope it to be structural. In this essay, I'm going to (try) to break down the themes, the characters, and what I believe could be why the story was written like this. I'll also touch on the art, the motifs and interpretability in it.

BEWARE OF SPOILERS FROM HERE ON!

For starters, the themes. There are three primary: neglect, pent-up feelings and desires, and fear of being stuck in a place where no happiness can be found. These themes are the driving force for the actions and choices of the characters.

Neglect.

Out of the three, this one is probably conveyed in the most upfront way. A visual way how it's shown is the drawing of characters as dark silhouettes, seemingly completely detached from the person perceiving them and unable to be reached.

Yoshie's family situation is a very clear case of neglect. Her parents seem to have no regard for her and are using her as a tool in their destructive life-style. She feels powerless against the two silhouettes sitting in front of the TV light, demanding her to get them something other than sparkling wine. And as she doesn't have control over her life at home, she finds solace in school as part of a class, and to not lose the connection she goes along with everything they do.

In the final chapter, Haruka's grandfather laments not seeing Haruka's suffering and leaving her on her own. Getting back to that later... But this situation is an ambiguous example. Haruka had decided to keep everything happening in school secret before already and she would've probably been evasive if probed. But grandfather should've probably tried to open her up because how could she have been fine. It's possible that he was holding out for her to do so when she would've felt like it, so that's why it's in a gray area I think.

Another example, although wrong, is what Ikegawa feels, sensing that Haruka is neglecting his feeling for her

This theme encompasses basically every character to some extent, but these examples are convenient to talk about here to reserve bigger characters for their own segments. Yoshie is also a very necessary addition into the story in my opinion because the type of abuse she experiences is not uncommon and it's portrayed viscerally.

Bottling emotions.

It's not easy to be open with emotions and let other people in on what's locked in your heart. And I don't think people should feel forced to put themselves out there like that, but it is healthy and relieving.
And that's what the theme is about. The characters seemingly live in an environment which makes them hide their feelings, often with hostility. In turn, the actors causing the suppression might not learn about the existence of the emotions because they're rendered invisible. It's a dangerous and toxic cycle that causes a lot of trauma to people.
But the emotions can be bottled up for only so long before they're released in an explosion.

The characters I'll use as an example here is Ikegawa. Although his character was not fully articulated as he's written with some uncomfortable implications. He was obsessed with Haruka, feeling something similar to love, which had been warped by having to hold it in. He definitely wasn't in a good headspace before either, but due to the class collectively hating Haruka, he played along, and that ended up turning his feelings into a jealous feeling of ownership and entitlement. He wanted to own Haruka. Maybe it could've been genuine love if the environment was better. With how it was, he would've become the enemy of the rest of the class if he tried being sincere and open with Haruka.
Honestly, I could be giving him too much credit with this analysis, but I feel that's the concept behind Ikegawa's character- It's a really deranged mindset that we get to see from him, but as to why he's like that, this is my interpretation. But anyways, this roughly brings me to the next theme.

Feeling stuck.

This theme is built on the setting, the small town of Ootsuma. A barren place with a decreasing population and with little comfort except the beautiful landscape that is infested with Hepatica Nobilis.

This serves as a core factor as to why the characters are constantly on edge and is something the characters iterate; there's nothing to do. Aiba is the only one who has found an avenue for expressing himself and he seemingly is satisfied with the photos he gets to take, although he wants to take pictures of something more beautiful, leading him to take photos of Haruka's burnt dad...

People need something to spend time and energy on because the thirst for fulfillment can also be bottled up.

Most everyone in Class 3-1 appears to feel without dreams or hope. Their time outside of home is spent by finding distorted relief in banding against someone and flaunting pride in being the school's last alumni. it's bleak. Their potential has no way to manifest.

I think this theme goes hand in hand with neglect. It's not like rural areas are bound to have outcomes like this, not at all. There obviously are things to do, but people generally need social interaction and activity and so being shunned by their parents, the classmates of Class 3-1 have broken down.

As a side-note, some members of Class 3-1 cite Haruka's existence as the catalyst of their behaviour in an impressive display of victim-blaming. To say that's what tipped the scales is glaringly wrong when taking into account that Rumi was the victim before Haruka moving in. I see it as a momentary self-rationalization which shows they haven't come to terms with how they've been victimized by their families themselves.

Haruka Nozaki.

She's quite unique as a main character. Despite her being the main perspective the audience follows, her personality is rather open-ended. The story gives a general understanding of her and her values, like the heartwarming love and care she holds for her family, but she's quiet about what she feels at any given moment and we don't see into her mind often either. There are many vague panels which leave her emotions up for interpretation. For an illustration, how exactly does Haruka feel about her revenge? Is she really as cold and unfeeling as she seems or do her actions pain her as is also hinted? What keeps her going?

In terms of which of the themes Haruka falls under, it's bottling emotions. She tries to endure the bullying and hides it from her family to not worry them. It's very wholesome that Shouka sees through Haruka and comforts her, but it's because she used to go through it when they lived in the big city. Haruka's strength is admirable, but it wasn't sustainable.

Haruka is also tied to the motif that is the title of the series, Hepatica Nobilis. A flower that braces snow and blooms in spring. Aiba notes the flower is alike Haruka. He thinks putting up with life and abuse is love, so for him Hepatica Nobilis is a symbol of love. But half way through the series the blanket of snow grows too thick and the flowers are drowned in it.

Mitsuru Aiba.

Yeah, reading chapter 15 for the first time was a shock. On a reread, I spotted multiple sketchy flags surrounding him, like how he kept a copy of Haruka/Shouko photo in his room. It's devastating because Aiba did feel like a ray of hope and his presence was comforting for both Haruka and me as a reader.

Pinpointing Aiba's character under one of the three themes isn't straightforward as his situation is very different from everyone else.

He grew into the person he is by being abandoned by his mother after he tried to protect her. From that point on he appears to have a mindset that she needed to be controlled and abused, he thinks she didn't know what was good for her. To be honest, her mom is on levels of fucked up that are hard to comprehend too, and I've got little clue about defining her without any more context. But that mindset extends to Aiba's own target of obsession, Haruka. And to "protect" her and garner her attention he's willing to go to awful lengths. At one point it becomes so delusional he goes out of his way to separate Haruka so she wouldn't have anyone but him left. And he makes an absolutely disgusting comment about being the only one to not abandon her even if her sister dies, implying her sister would be "abandoning" her.

Anyway, there are tons of interesting panels and details in this manga, but in regards to Aiba, there are two that I want to bring up.

The first is his excuse for taking the picture of Haruka's dad and Shouko in the fire, which he tries to explain as him admiring the father's heroic act. I think this reason might contain a bit of truth, the contrast of his father and Haruka's father could've evoked something like that.

The second thing is the final page of chapter 14 where Aiba steps on a Hepatica Nobilis but looks completely unfazed despite having compared the flower to Haruka. I believe the implication is that he's oblivious to his own actions and that he really doesn't see how he hurts people.

Taeko Oguro.

The third theme is most prominent in Oguro. She has a dream, unlike people around her (from what we see at least). But it can't be fulfilled in Ootsuma. She literally does feel stuck and she pleads to be allowed to chase her wish, but isn't permitted. This once again results in someone bottling up their emotions; ambition and even hatred for the place that holds her down. She starts too view everyone around her as abnormal for being content on the surface, even prideful of their alumni status. She even openly denies her dream. The outcome is that she uses everyone to feel in control and leads everyone against Haruka.

Her relationship with Haruka is probably the most notable thing about her character. She was immediately interested in Haruka as she came from Tokyo, but she quickly becomes disappointed because Haruka doesn't really want to go back unless her family does. She becomes spiteful as she, someone who'd give everything to go there, can't, but the one who could isn't even interested. In her eyes it must be a great injustice, which, well, could be argued. Besides all of that though, she's jealous of Haruka's attention which only inflates her spite.

As a side note, one interesting detail is how she prefers to hurt Rumi's hands. For her hands are important because she'd need them for her dream job. Also, her way of inflicting self-harm is biting her hands.

Rumi Sayama & Kyouko Minami.

I'm bundling them together because they're similar and I'm trying to condense this review.

Both are depictions of someone who is completely cornered, basically a wild animal that can only turn around and attack the hunter. As for Rumi, she's also got the thing with obsession and disillusionment going on.

The circumstances of these characters are tragic. When it's shown how casually Rumi is bullied despite being one of the Ootsuma people and her perpetual state of hear, it's terrifying to think what she's been through. Her design often looks monstrous and she was indeed molded into one. She's been broken through sheer abuse by her classmates. Totally cornered between Oguro and Haruka. She's at a stage where she thinks it's better if she dies liberated than to continue being abused. And the layer of her admiration for Oguro just muddies this into something so indescribably disgusting.

Kyouko is in a quite a similar position, but perhaps even more tragic. She tried to redo her school life and get a new start, for it to end up exactly the same, being bullied by her own students. Even an adult isn't invincible, the scars she's gotten are nigh irreparable. She falls into the two latter themes.

Grandpa.

Usually a grandfather character in a story is a relatively straightforward character. That rings true for Misumisou too. At least on the surface. He's simply a character who supports Haruka. But, there is something more to him, the fact that he is quite likely aware of Haruka's actions.

Firstly, assuming he actually does believe Haruka and thinks she's attending school, if that's the case, I'm still worried because he shouldn't let her. Haruka absolutely shouldn't be going to school in her situation. But I don't think this is it. There's a scene where he is looking through Haruka's clothes and in a very cryptic panel we see him find what appear to be bloodstains on her jacket. It's hard to believe he's oblivious to what it could indicate.
Also, at one point Haruka questions him about why he hasn't asked anything, and grandpa also very enigmatically states that Haruka can tell him when she's ready to do so.
Although the final chapter would suggest that he actually didn't knew anything, it might be that his mind isn't clear at that point and that his sentiments aren't to be taken as facts. Well, he does see an illusion of Haruka after all.
But if the possibility that he knew what Haruka was doing is true, that's a disconcerting prospect. It's true neglect. Also it would actually parallel one of the parents who was glad about their child being a perpetrator instead of a victim because it'd mean there "wouldn't be anything to worry about".

Okay, these are all of the main characters. I don't think I need to bring the minor ones up. Maybe the breakdown isn't as complete and thorough as I imagined, but this covers it about anyway. The review is getting lengthy and I still have other subjects to go over.

The story's intent.

Short stories are fascinating. When a story is so short, assuming it's not because of being axed or anything, it indicates that it's written for a more defined purpose, maybe even for a goal. The author has something they want to say or share or put out in the open, whatever. And so, with this in mind, what might be the purpose of Misumisou?

Well, the answer is quite obvious, isn't it? In a broad sense, it's a message about what neglect leads to. But I feel it's a very particularly crafted story and it isn't just trying to explore a concept. I feel it's actually trying to gut punch the reader to wake up about the topic and make them feel strong feelings towards it. Trying to hammer in how ugly the consequences can be. The grotesque manner of depicting the bullying is like it is for that purpose, I think that it is, at least.

The atmosphere and the interpretability.

One of the standout aspects of Misumisou for me is the art, particularly the style. It's both unique and fitting. Cutesy round characters that have whiplashing contrast with the carnage and horror. And the backdrops are slim and beautiful, although bleak of course. I really like the atmosphere, it's lonely and isolate, but also fresh because of the touch of winter and cold. But the ever-increasing amount of snow feels like a representation of things escalating. At the start of the manga, it's all quiet, only light snowfalls, but as the revenge story begins, it drastically intensifies.

But as for what I appreciate the most, it's the ambiguity. So many panels leave a lot of room to interpretation. Despite having read the story a couple of times and taken notes of it as well as having discussed it, there are still many moments where I don't understand the full depth behind an expression or a line of dialogue.

The conclusion.

I think Misumisou is a very well executed and important manga. It depicts themes that are really prevalent and is a wake up call, not a study. The people I've talked about the manga with usually consider its lack of exploration of the themes an issue, but I don't see it that way. Well, I get it, but I think the way Misumisou does it is also needed. What's uncanny is that this story doesn't feel that unreal. That's certainly a thought.

Well, this review is long. I think Misumisou deserves a lot of effort because it's so obscure and I'd like for there to be at least something about it on the internet, at least in English anyway, I'm not sure how the situation is in Japanese. Also, it's a short enough story that a full breakdown is plausible. Also, my first serious review was of this, but that was a terrible attempt and it was practically just praise without any analysis or substance to speak of.

I haven't even recommended the manga yet. But then again, it's not really about that. I'm attempting to counter the more negative opinions which I've seen circling around. Although if you haven't read Misumisou, then most importantly, how did you even scroll all the way down here? But do go and read Misumisou, lol
