Kohei Horikoshi, the author of My Hero Academia, released a one‑shot manga titled Quit Laughing, Shijima in the latest issue of Weekly Shonen Jump on August 12, 2026. The work is presented as a supernatural adventure set in Konoshiro City and centers on high school student Azumi and his classmate Shijima.

The story follows Azumi, who can see grotesque humanoid figures, and Shijima, a popular student whose involvement in a town tradition leads to her being designated as a sacrifice to a deity that protects the community. The narrative combines elements of supernatural action with a horror premise.

The manga includes a premise in which a select group of families maintains a tradition of human sacrifice to ensure the town’s prosperity. Azumi discovers the tradition, confronts a monster, and declares his love before killing the creature. A flashback explains that Shijima’s popularity originates from bullying over her teeth and her forced acceptance of the sacrificial role. The story’s tone remains primarily action‑oriented, with limited exploration of psychological aspects. The artwork and monster designs have been noted for their distinct visual style. The piece concludes with Azumi assuming a vigilante stance reminiscent of his role in My Hero Academia, suggesting potential for a full series.

While the one‑shot does not fulfill the expectations of a horror narrative, it provides a supernatural storyline and leaves the prospect of a full manga open.
