The Flowers of Evil Review: The Manga That Made Me Uncomfortable in the Best Way

This is not a manga about flowers. It's about the specific shame of adolescence — how we become capable of things we can't take back.

Quick Take

• A slow-burn psychological horror that operates entirely through social discomfort and shame
• Nakamura is one of the most compelling antagonist-protagonists in contemporary manga
• The final arc completely reframes everything you thought the story was about

Who Is This Manga For?

• Readers who want manga that actually disturbs them — not with gore, but with psychological truth
• Fans of Oshimi's other work (Inside Mari, Blood on the Tracks)
• People who remember middle school as something survivable but not pleasant
• Adults who want to understand a certain kind of teenage self-destruction from the inside

Story Overview

Takao Kasuga is an eighth grader obsessed with Baudelaire. He considers himself different from his classmates — more sensitive, more literary, destined for something larger than the small town he lives in. This is the kind of self-image that middle schoolers are very good at constructing and very bad at testing.

Then he steals his classmate Saeki's gym clothes. On impulse. Without understanding why.

Nanako Nakamura sees him do it. Instead of telling anyone, she blackmails him: wear the gym clothes under your own clothes, and do whatever I say. Kasuga, terrified of being exposed, agrees.

What follows is a slow, nauseating descent into humiliation, connection, and something that might be love — or might be two lonely people destroying each other because they don't know another way to reach out.

Oshimi's genius is that Nakamura is not simply a villain. She's someone who has decided that conventional life is a lie, that "normies" (her word) are frauds, and that the only honest thing is to break everything open. She sees in Kasuga's theft evidence that he secretly agrees with her. She might be right. He might not be able to live with what that means.

The story is divided roughly in half. The first half is middle school: intimate, claustrophobic, almost unbearably tense. The second half jumps years ahead and recontextualizes everything. The adult Kasuga looking back at his eighth-grade self is a completely different kind of horror.

Characters

Takao Kasuga — Thinks he's exceptional. Is, in fact, ordinary — which is both his tragedy and eventually his salvation. His arc is about the distance between who we tell ourselves we are and who we actually become.

Nanako Nakamura — Cruel, perceptive, genuinely strange. She's the most interesting character Oshimi has ever written. Her worldview is coherent, even when her actions are destructive. You can understand her without agreeing with her, which is the most disturbing thing about her.

Nanako Saeki — The girl whose clothes were stolen. Sweet, earnest, genuinely kind — everything Nakamura hates about conventional goodness. Her relationship with Kasuga is a mirror to the Nakamura relationship: what genuine connection might look like versus what Kasuga actually has with Nakamura.

Art Style

Oshimi's early work has a deliberately ugly quality. The faces are distorted when emotion peaks — stretched, gaping, wrong in the way that raw feeling is wrong when you see it on someone's face. This is intentional. He's drawing shame and obsession, and shame doesn't look pretty.

As the story moves into its second half and adult years, the art softens slightly. The control becomes more visible. You get the sense that Kasuga has learned to contain himself — and the art reflects that.

The famous sequence where Kasuga and Nakamura run through town, screaming, tearing things apart — it's one of the most visually intense sequences I've ever read in a manga that contains no violence.

Cultural Context

Japanese middle school culture has specific social pressures that the manga uses: the homeroom classroom as a contained social ecosystem, the way individual transgression becomes community scandal, the particular loneliness of someone who decides they don't belong to the group and then discovers that not belonging is its own kind of prison.

The Baudelaire obsession is important. Les Fleurs du Mal (The Flowers of Evil) is Baudelaire's collection of poems about beauty found in decay, transcendence found in transgression. Kasuga reads it without quite understanding it. Nakamura understands it better than he does. Part of the tragedy is figuring out which one is right.

What I Love About It

I've thought about this manga for years since I finished it.

Not because it's comfortable to think about. Because Nakamura said something that I couldn't unhear. There's a moment where she essentially describes the social performance of being a "good person" as a form of cowardice — choosing comfort and approval over honesty about what you actually want and feel. And she's partly right. The part of me that agreed with her was unsettling.

Oshimi doesn't vindicate Nakamura's methods. He doesn't punish them either, not simply. What he does is show you what it costs to choose her path and what it costs to choose the other one. The final volumes are about a man in his twenties trying to understand what he did and didn't do at age fourteen. That reckoning feels honest in a way that made me deeply uncomfortable.

That's what great horror is supposed to do.

What English-Speaking Fans Say

This is a divisive manga on Reddit and Goodreads. Some readers find Nakamura's behavior impossible to sympathize with, and find the experience of watching Kasuga enable her unpleasant without sufficient payoff. Others — myself included — think the discomfort is the point.

The 2013 anime adaptation (using rotoscoping, which gave it a deeply unsettling visual quality) is also discussed alongside the manga. Most agree the manga ending is far more complete.

Memorable Scene ⚠️ Spoiler Warning

The scene where Kasuga, as an adult, finally meets Nakamura again — and she doesn't remember him the way he remembers her — is the quiet gutpunch the whole story was building toward. Not dramatic. Not violent. Just the specific horror of discovering that the relationship that defined your adolescence didn't define the other person's the same way. She was doing something to him. He was doing something entirely different.

Pros & Cons

Pros

• One of the most psychologically honest manga about adolescence ever written
• Nakamura is a genuinely compelling, original character
• Art perfectly calibrated to the story's emotional register
• The second half rewards everything you endured in the first

Cons

• Genuinely uncomfortable reading experience — intentionally so, but not for everyone
• Kasuga can be frustrating as a protagonist if you need your leads to make good choices
• The middle volumes can feel repetitive — the same loop of shame and transgression
• If you need catharsis, this may not deliver it cleanly
• Some readers find the ending unsatisfying — healing is quiet here, not triumphant

Is The Flowers of Evil Worth Reading?

Yes — if you can stomach discomfort. It's one of the most psychologically honest manga I've read, and the kind of story that keeps working on you after you've finished it. The discomfort is the point. That's either a feature or a deal-breaker, depending on who you are.
