What we know so far about Kamiyashiro: Jikosatsu no Kei
The official description reveals that Kamiyashiro follows Kei, an assassin who engineers “accidental murders” using clever gimmicks. Kishimoto announced the manga via X and confirmed an early launch on LINE Manga on January 25, with serialization to begin on Manga Box at a later date. Beyond the premise and release windows, few plot specifics have been revealed, making this a highly anticipated title for fans of Kishimoto’s previous work.
Early release details and where to read
Kamiyashiro will have an early run on LINE Manga starting January 25, offering readers an advance look before its formal serialization on Manga Box. For official updates and chapter rollouts, follow Kishimoto’s announcements on his X account and Manga Box’s channels—both are the primary sources for release timing and platform availability.

Meet the protagonist: Kei, the accidental assassin
The concept of an assassin who specializes in making killings appear accidental immediately sets Kamiyashiro apart from a typical hitman story. This premise promises tightly plotted setups, inventive contraptions or “gimmicks,” and a moral gray area where intent, blame, and consequence are blurred. Expect suspenseful chapter hooks, investigative elements, and the potential for both dark humor and intense drama as Kei navigates contracts, rival killers, and law enforcement scrutiny.
Seishi Kishimoto: a quick career overview
Seishi Kishimoto has a diverse catalog spanning fighting manga, action fantasy, and inventive one-shots. Notable works include:
- O-Parts Hunter (666 Satan) — Serialized in Shonen Gangan from 2001–2007; a supernatural adventure series that introduced many readers to Kishimoto’s early style. (English publication by Viz Media.)
- Blazer Drive (2008–2010) — A fighting/action manga with high-energy battles and technology-driven powers.
- Kurenai no Ōkami to Ashikase no Hitsuji (The Crimson Wolf and the Trapped Sheep) (2011–2013) — An action fantasy with darker tones and dramatic stakes.
- Sukedachi Nine (Assist Nine) (2014–2016) — A series mixing action with ensemble cast dynamics.
- Mad Chimera World (2017–2018) — A later action title showcasing Kishimoto’s evolving art and worldbuilding.
- Short works and one-shots — Kishimoto contributed the “Yobigami” one-shot to Manga Box in 2021 (credited to a fictional in-show author), and launched Monster Life and the Earth (Monster no Isha) on Manga Box in 2021 to celebrate the app’s anniversary.
Seishi is also widely known for being the younger twin brother of Masashi Kishimoto, creator of Naruto, though Seishi’s storytelling voice and art have always maintained a distinct identity.
What fans can expect in tone and storytelling
Given Kishimoto’s track record, Kamiyashiro will likely blend kinetic action with inventive gadgetry and a strong sense of pacing. The “accidental murder” angle points to carefully constructed plot mechanics—think elaborate setups where small details determine whether a death looks like misfortune or foul play. Readers can expect:
- Inventive, plot-driven mysteries that hinge on clever mechanics.
- A morally ambiguous protagonist whose methods invite debate.
- Action sequences that emphasize technique and situational advantage rather than only brute force.
- Possible investigative or cat-and-mouse dynamics with law enforcement or rival operatives.
Potential comparisons
While Kamiyashiro’s premise is unique, elements of the series may appeal to readers who enjoy suspenseful thrillers with clever twists and assassins who operate with a signature style. Expect more cerebral setups than straight-up shonen tournament arcs, though Kishimoto’s action sensibilities should still deliver satisfying combat beats when they occur.
Why Kamiyashiro matters for Kishimoto’s catalog
This new title gives Kishimoto an opportunity to explore darker, more suspense-driven storytelling while retaining his strengths in choreography and imaginative concepts. For longtime followers, it’s a return to serialized creativity on a digital platform (Manga Box) where Kishimoto has published before. For new readers, Kamiyashiro provides an accessible entry point: a high-concept hook with clear stakes and a memorable lead.
Where to follow official updates
Keep an eye on Kishimoto’s official X post announcing the manga for teasers, character art, and release notes.
