From Heroes to Horrors: Kohei Horikoshi’s "Quit Laughing, Shijima" and the Evolution of a Shonen Titan

After a decade of defining the landscape of modern manga with the global phenomenon My Hero Academia, Kohei Horikoshi has finally stepped back into the spotlight. Two years after concluding the sprawling saga of Izuku Midoriya and his peers, Horikoshi has returned with a new one-shot, Quit Laughing, Shijima, published in the latest issue of Weekly Shonen Jump. While the manga industry and its international fandom had been buzzing with speculation about the author’s next move—often fueled by lighthearted memes regarding his "unemployment"—the release marks a significant, albeit divisive, transition for the mangaka.

Billed as a foray into the horror genre, the one-shot has left critics and readers alike with a complex question: Can a master of action-packed shonen spectacle successfully pivot to the intimate, skin-crawling dread of psychological horror?

The Premise: A Seaside Mystery

Set in the bustling coastal locale of Konoshiro City, a town boasting a surprisingly specific population of three million, the story follows Azumi, a high school student navigating the mundane anxieties of his second year. Azumi is characterized by his desire to drift through life without the burden of long-term planning, a stark contrast to the driven, goal-oriented protagonists of Horikoshi’s previous work.

His life is centered around his infatuation with Shijima, a bubbly, loud-laughing girl who serves as the social anchor of their school. However, Azumi harbors a terrifying secret: he possesses the ability to perceive grotesque, humanoid entities lurking in the bay. When one of these creatures begins to encroach upon dry land—and specifically, when it begins to stalk Shijima—the narrative shifts from a slice-of-life romance into a race against a sinister, long-standing tradition. Shijima’s sudden disappearance from school triggers a revelation: the town has been maintaining a dark, occult pact with a godlike entity residing in the water, and Shijima has been chosen as the next human sacrifice to ensure the city’s continued prosperity.

Chronology of a Transition

The road to Quit Laughing, Shijima has been one of anticipation and artistic evolution.

• 2022: As My Hero Academia moved toward its final arcs, Horikoshi openly expressed his desire to experiment with the horror genre. He cited a fascination with the unsettling and the macabre, surprising fans who had only ever seen his mastery of superhero action.
• August 2024: My Hero Academia concludes its ten-year run. The "unemployed Horikoshi" meme becomes a staple of social media, as fans track his transition from a grueling weekly deadline to a period of creative recuperation.
• Mid-2025: During this period, Horikoshi releases a series of high-fidelity illustrations on social media, showcasing a shift in his artistic style—moving away from clean, heroic lines toward more textured, shadowed, and eerie compositions.
• August 12, 2026: Quit Laughing, Shijima is officially published in Weekly Shonen Jump, marking Horikoshi’s first major narrative contribution since the end of My Hero Academia.

Analyzing the Horror Deficit

Despite the marketing push framing the one-shot as a horror piece, the consensus among readers is that the work functions more as a "supernatural action" story. The true hallmarks of Japanese horror—psychological decay, the erosion of the mundane, and the slow, inevitable creep of dread—are present only in flashes.

In the tradition of masters like Junji Ito or the unsettling social critiques found in The Summer Hikaru Died, true horror relies on the subversion of comfort. Quit Laughing, Shijima establishes a setting that feels ripe for such subversion but ultimately chooses the path of hero-led resolution. The monsters, while visually striking and grotesque, serve primarily as obstacles to be defeated by the protagonist rather than as existential threats that reshape the fabric of reality for the characters.

The narrative structure follows a familiar "sacrifice" trope—a plot device seen in works like Wicker Man or Higurashi: When They Cry. While these stories use the sacrifice as a vehicle for uncovering deep-seated communal trauma, Horikoshi’s version moves quickly toward an action-oriented confrontation. When Azumi rushes to save Shijima, he doesn’t just face the horror; he fights it, effectively "killing the monster" while professing his love. This dynamic, while satisfying in a shonen context, deflates the tension required for true horror.

Supporting Data: The Art of the Unsettling

Where the one-shot excels is in its character design and the specific, grounded details of its horror elements. The flashback sequence involving Shijima is perhaps the most effective part of the narrative. By revealing that Shijima was once bullied for her appearance—specifically her teeth—and that her current "popularity" is a manufactured byproduct of her selection as a sacrifice, Horikoshi taps into a genuine, disturbing social commentary.

This is where the story hints at the potential for greatness. The idea that a community would systematically manipulate a young girl into accepting her own death under the guise of "honor" is far more terrifying than the monster in the bay. It mirrors the psychological abuse found in works like A Questionnaire on the Mouth, where the horror is not the supernatural element itself, but the human complicity required to sustain it.

Implications for the Future

The ending of the one-shot offers the strongest clue about Horikoshi’s trajectory. Azumi, standing on a rooftop in a pose that consciously mirrors Deku’s iconic imagery from My Hero Academia, essentially evolves into a supernatural vigilante. He is no longer a student, but a protector taking on the mantle of challenging dark traditions.

This suggests that Quit Laughing, Shijima is not intended to be a standalone horror masterpiece, but rather the pilot for a potential series. If the goal was to test the waters of a new genre, the implications are clear: Horikoshi is not abandoning the emotional, high-stakes storytelling that made him a household name. He is simply expanding his palette.

Official and Fan Reception

The reception has been a blend of admiration for his technical artistic growth and a mild disappointment regarding the generic nature of the plot. Critics note that for a writer of Horikoshi’s caliber, the reliance on standard shonen tropes is a safe bet, but perhaps a missed opportunity to truly innovate within the horror space.

However, fans have largely embraced the one-shot for what it is: a fun, supernatural romp that showcases the author’s continued ability to craft compelling characters. The emotional core—the bond between Azumi and Shijima—remains the driving force. Even in a horror setting, Horikoshi cannot help but lean into the themes of sacrifice, companionship, and the courage to fight against impossible odds.

Conclusion: A New Chapter

Quit Laughing, Shijima is a fascinating case study in artistic transition. It highlights the difficulty of moving from a genre defined by hope, growth, and victory (shonen) to one defined by helplessness, dread, and loss (horror).

While it may not stand as a pillar of the horror genre, it serves as a bridge. Horikoshi is clearly experimenting with darker, more textured themes, and the artistic prowess on display suggests that he is far from finished. Whether this leads to a full-blown series or serves as a brief detour before his next grand project, one thing is certain: the world is watching, and the "unemployed" era of Kohei Horikoshi has officially come to an end. The monsters in the bay may have been defeated, but the potential for the darkness he is crafting is only just beginning to surface.
