For years, shonen anime have adhered to a well-known formula. These series typically feature valiant heroes, emphasize the power of friendship, celebrate hard-fought triumphs, and convey a core message that determination can conquer any hurdle. While classic shonen tales are crafted to inspire hope and positivity, not all stick to this conventional script.
Recently, a wave of darker anime has begun to challenge the fundamental conventions of shonen. These narratives thrust characters into morally ambiguous scenarios, subject them to profound losses, and sometimes dismiss the notion that good inevitably triumphs over evil. While the grim themes in these darker series might seem daunting, their raw realism is precisely why they resonate so deeply with audiences.
In traditional shonen stories, heroes typically grow stronger and more secure as they inch towards victory, often undergoing a training arc that equips them to eventually defeat the antagonist. However, Attack on Titan subverts this expectation by stripping away the comfort of victory, instead shedding light on the relentless cycle of war.
Victory Isn’t Always Worth It in Attack on Titan
A typical narrative trope in shonen is that its heroes steadily become safer and stronger as they work towards a victory, often going through a training arc that allows them to finally secure a hard-earned victory against the villain. What Attack on Titan does to break this rule is take the catharsis of victory away to highlight the cyclical nature of war.
When Eren and the Survey Corps finally secure a small victory against the titans, it often comes at the expense of beloved characters, such as Sasha Braus’ death as revenge for their attack on Liberio. Attack on Titan also subverts the usual positivity that comes with a shonen battle victory by revealing even worse truths after the fact, driving home the point that no good can come from violence.
Almost All of Death Note’s Characters are Morally Grey
Image via MadhouseShonen tends to position its protagonists as morally correct, while its antagonists are indisputably evil. There are plenty of anime that attempt to subvert these expectations, but few do it as well as Death Note. Light Yagami, the series’ protagonist, is also the villain of the story, coldly murdering criminals and anyone who gets in his way in his quest to achieve a new world order.
That makes L, who technically serves as Death Note‘s antagonist as he tries to take down Kira, the “hero” character. However, even he isn’t close to actually being a paragon. L is constantly shown as morally grey as he works with criminals, tortures Misa, and keeps Light chained to him 24/7 to solve the case. It’s up to fans to reckon with their own personal morals as they decide who to side with.
Denji Has No Grand Ambitions in Chainsaw Man
Endless shonen anime show the protagonist having a noble dream that leads them on a journey of self-discovery. Denji is far from an inspirational character in Chainsaw Man, as he’s not motivated by a grand desire to save the world. At the beginning of the story, the only thing that keeps Denji going is his basic need for food, shelter, and human affection.
Denji is not interested in saving humanity from devils like many other Public Safety devil hunters. When pressed for his motivation, it usually always comes down to needing food or wanting to go on a date with Makima. Chainsaw Man is not an aimless story, though, as Denji’s needs are true to his traumatic upbringing, and far more relatable to fans than dreaming of saving the world.
Jujutsu Kaisen’s Mentors Can’t Always Protect Their Students
Image via Studio MAPPAThe mentor, an older, more experienced character who guides the protagonist through their training arc, is a classic shonen anime trope. Often, mentors do eventually die, but usually as a plot device to show that the hero is now strong enough to fight on their own. In Jujutsu Kaisen, mentors try their best to protect their students, but continually fail to shield them from trauma and death.
The Shibuya Incident serves as the clearest example of Jujutsu Kaisen‘s subversion of the mentor trope. Multiple mentors such as Akari Nitta, Kento Nanami, and even Satoru Gojo himself are injured or sealed during the incident, leaving the students of Tokyo Jujutsu High to save them and fight on the battlefield alone. Rather than presenting adulthood as a safety net, Jujutsu Kaisen emphasizes the failure of established systems, making its world feel far more dangerous than a typical shonen anime’s.
Strength Isn’t Won Through Sheer Determination in Hunter x Hunter
Although Hunter x Hunter doesn’t seem like a dark shonen, the realities of its world are more sinister than they appear on the surface. In many shonen anime training arcs, heroes gain power-ups by always believing in themselves and never giving up. Hunter x Hunter‘s Nen system makes it clear that power only comes with severe limitations and consequences, meaning that greater strength usually comes with greater risk.
Hunter x Hunter‘s power philosophy reaches its peak during Gon Freecss’ battle with Neferpitou, where his overwhelming transformation is not a triumphant breakthrough, but a devastating act of self-destruction fueled by grief and rage. Rather than celebrating limitless growth, the anime presents power as a dangerous resource that can permanently alter a person’s life.
Good Does Not Triumph Over Evil in Devilman Crybaby
Image via Science SaruDevilman Crybaby may have a mature rating, but the Devilman manga was originally published in Kodansha’s Weekly Shonen Magazine. It introduced a story that moves towards catastrophe rather than a triumphant ending, something that dark shonen fans have come to love. Akira Fudo begins as a sensitive young teen, but his transformation into the Devilman only brings chaos and destruction.
Throughout Devilman Crybaby, Ryo Asuka convinces Akira that the only way to defeat the demons is by taking on their powers. Akira’s transformation changes his body in ways he cannot control, leading him to take increasingly violent action against demons and humans alike. The anime’s rather nihilistic ending, which culminates in the destruction of Earth, is at complete odds with most shonen narratives.
The Promised Neverland Prioritizes Intelligence Over Strength
Battle-focused shonen anime revolve around powerful fighters overcoming increasingly dangerous enemies. The Promised Neverland breaks that formula by making intelligence, strategy, and information the most powerful tools for survival. From the very beginning, direct confrontation is impossible for Emma, Norman, and Ray, forcing them to rely on careful planning instead.
The demons in The Promised Neverland have complete control over the environment, and are physically stronger than the orphaned children, meaning that major victories are only achieved through observation, deception, and teamwork. For example, to defeat their caretaker Isabella, the orphans do not confront her in battle, but secretly recruit allies and plan an escape route to run away from her instead.
There’s No Such Thing as Plot Armor in Akame ga Kill!
Image via Studio White FoxIt’s easy to fall into a sense of security with shonen when characters can seemingly always get out of the most impossible situations. Fans can usually expect the main cast to make it to the end of an anime’s story, but Akame ga Kill! treats every character as equally expendable. Regardless of importance, popularity, or narrative potential, no character is safe.
By removing the safety net of plot armor, Akame ga Kill! makes every battle feel genuinely dangerous and unpredictable. Throughout the series, members of the Night Raid are killed in brutal battles. Sheele’s death early in the series, despite her appearance as a long-term mentor figure, sets the expectation that fans can never be sure that their favorite character will survive.
The dark shonen genre thrives on teaching fans about hard truths, and Fullmetal Alchemist: Brotherhood does this from the outset. The anime begins with an alchemy experiment going wrong, which results in Edward losing limbs and Alphonse losing his entire body. Their original goal to resurrect their mother is never achieved, despite their long journey to obtain a Philospher’s Stone.
Fullmetal Alchemist: Brotherhood is full of instances where, despite the determination and growing alchemical powers of the Elric brothers, there are some losses that cannot be reversed. Another heartbreaking example is Nina Tucker, a young girl who is turned into a chimera by her father, and who can only be killed by Scar as a mercy afterward.
Hell’s Paradise Forces Fans to Sympathize With Typical Villains
Image via MAPPAGabimaru, Hell’s Paradise‘s protagonist, would be a villain in any other shonen anime. He’s an assassin responsible for countless deaths, yet he remains one of the most sympathetic characters due to his desire to reunite with his wife and leave his violent past behind. Similarly, the executioners sent to supervise the criminals are not purely heroic, as many are driven by personal ambition rather than altruism.
Rather than dividing its cast into heroes and villains, Hell’s Paradise presents a world where survival often requires compromise, where even well-intentioned characters are forced to make ruthless decisions. Threats on the island cannot be understood through simple moral labels, and the series’ moral complexity challenges shonen’s tendency to portray conflicts in black-and-white terms.
