KILL BLUE is officially returning for a second season, continuing the unusual school life and dangerous missions of legendary assassin Juzo Ogami.
The sequel was confirmed on June 27, 2026, immediately after the Japanese broadcast of the first season’s 12th and final episode.
Original manga creator Tadatoshi Fujimaki celebrated the announcement with a newly drawn illustration showing Juzo holding a school textbook while firing a handgun, perfectly representing the series’ combination of middle-school comedy and professional assassin action.
Season 2 is officially in production, but the initial announcement did not reveal a premiere date, episode count, trailer, returning production team or international streaming platform.
KILL BLUE Season 2 Is Officially in Production
The second season was announced only moments after the conclusion of Episode 12, titled “Course.”
The timing confirms that the anime will continue beyond Juzo’s first major group of missions as a middle-school student. However, the production committee has not stated how far work on the sequel has progressed.
- Season 2 status: Officially confirmed
- Announcement date: June 27, 2026
- Release date: Not yet announced
- Episode count: Not yet announced
- Animation studio: Not yet reconfirmed
- Returning cast: Not yet formally announced
- International streaming: Not yet confirmed
No animated teaser or Season 2 key visual was released. The celebratory image was drawn by Fujimaki rather than presented as footage or character artwork from the continuation.
Tadatoshi Fujimaki Celebrates the Sequel
Fujimaki thanked the anime’s staff, everyone involved with the production and the viewers who supported the first season.
The creator admitted that he still does not know precisely when Season 2 will arrive or what form its content will take. He nevertheless expressed hope that the continuation will preserve the relaxed and entertaining atmosphere of the first season.
His new illustration captures the central contradiction that defines Juzo’s new life. He is still a highly trained killer capable of handling firearms and dangerous opponents, but he must now carry textbooks, attend classes and behave like an ordinary teenager.
Season 1 Concluded After 12 Episodes
The first season premiered in Japan on April 11, 2026, and completed its run on June 27.
Its 12 episodes introduced Juzo’s transformation, his assignment at a middle school and the classmates who gradually become involved in the mysteries surrounding his new body.
The anime was broadcast through TV Tokyo and streamed internationally on multiple platforms, including Crunchyroll in supported regions.
The complete first season is also scheduled to receive a Japanese Blu-ray box release on November 11, 2026.
What Is KILL BLUE About?
KILL BLUE follows Juzo Ogami, a 39-year-old professional assassin famous for completing even the most difficult assignments.
Juzo has spent most of his adult life working as a killer. He understands weapons, surveillance and combat, but knows almost nothing about ordinary school life.
During one mission, he is stung by a mysterious wasp and loses consciousness. When Juzo awakens, his adult body has been transformed into that of a 13-year-old boy.
Before he can properly investigate the condition, his employer gives him another assignment. Juzo must use his younger appearance to infiltrate a middle school connected to the research that may have caused his transformation.
The mission forces the legendary assassin to attend lessons, interact with teenagers and experience the youth he never had.
At the same time, rival killers and criminal organizations continue appearing, ensuring that his school life never becomes completely peaceful.
Juzo Ogami Receives an Unexpected Second Youth
Juzo initially views his new body as an inconvenience that must be reversed as quickly as possible.
His physical appearance may have changed, but he still possesses the memories, instincts and experience of an elite adult assassin.
This creates a considerable advantage when criminals underestimate him. A small student carrying a school bag does not immediately appear as dangerous as a veteran hitman.
The transformation also creates limitations. Juzo’s body does not always possess the strength, reach and endurance he had as an adult, forcing him to adjust established techniques and make more creative use of the environment.
His greatest challenge may be social rather than physical. Homework, friendships, school clubs and adolescent misunderstandings are unfamiliar territory for someone raised around professional violence.
Yuko Sanpei Voices the Younger Juzo
Yuko Sanpei voices Juzo after his transformation into a middle-school student.
The performance must communicate that the young character seen on screen is mentally an experienced 39-year-old man.
Juzo frequently responds to school situations with the seriousness of someone evaluating an assassination mission, even when his classmates are discussing homework or club activities.
Sanpei balances that adult mentality with the physical reactions and comedic situations created by Juzo’s younger body.
Shunsuke Takeuchi Voices Adult Juzo
Shunsuke Takeuchi portrays Juzo in his original adult form.
The adult version establishes the assassin’s intimidating reputation before the transformation changes how everyone perceives him.
Flashbacks and other scenes involving his former body reinforce the contrast between the feared professional killer and the student attempting to blend into a classroom.
Noren Mitsuoka Is Connected to Juzo’s Transformation
Noren Mitsuoka is one of Juzo’s most important classmates and a central figure in the mystery surrounding the wasp that changed his body.
She is connected to Mitsuoka Pharmaceuticals, making her family potentially relevant to the research Juzo was ordered to investigate.
Noren is intelligent and capable, but she also becomes involved in the increasingly strange events surrounding her new classmate.
Her relationship with Juzo develops through school activities, danger and his attempts to hide the truth about his identity.
Fuka Izumi voices Noren in the Japanese version.
Kotatsu Nekota Brings Juzo Into the Home Economics Club
Kotatsu Nekota is another important classmate introduced during the first season.
His involvement with the Home Economics Club gives Juzo another opportunity to experience ordinary school activities that have nothing to do with assassination.
The club becomes one of the places where the series most clearly embraces its school comedy, allowing the characters to cook, interact and form friendships between dangerous missions.
Shuichiro Umeda voices Kotatsu.
Shin Kohazame Adds Another Assassin to the Story
Shin Kohazame is an assassin whose presence complicates Juzo’s attempts to maintain an ordinary student identity.
Characters connected to the criminal world can recognize abilities and behavior that Juzo’s classmates may overlook.
His arrival reinforces that Juzo cannot completely escape his former profession simply by wearing a school uniform.
Daisuke Sakuma voices Shin.
Tenma Tendo Becomes a Powerful School Rival
Tenma Tendo is another major character introduced during the first season.
He possesses exceptional physical talent and a strong personality capable of challenging Juzo inside the school environment.
Juzo may have decades of combat experience, but he cannot resolve every disagreement by behaving like a professional killer.
Tenma’s involvement creates competition, comedy and situations where Juzo must balance his abilities against the need to preserve his cover.
Takeo Otsuka voices Tenma.
The Rindo Brothers Bring Professional Danger to the School Story
Kazuma Rindo and Eiji Rindo are a highly dangerous pair of assassin brothers.
Their combat experience makes them credible threats to Juzo despite his legendary reputation.
Kazuma is voiced by Shoya Chiba, while Yoshiki Nakajima portrays Eiji.
The brothers represent the more violent side of KILL BLUE, contrasting with the increasingly comfortable school life Juzo begins building.
Main Japanese Cast From Season 1

These performers have not yet been individually reconfirmed for Season 2. The continuation’s official cast list will be released through a future update.
CUE Produced the First Season
CUE handled animation production for the first season.
The anime required the studio to move between firearm action, hand-to-hand combat and quieter school comedy without making the two sides of the story feel disconnected.
The contrast is fundamental to KILL BLUE. Juzo can be fighting a professional assassin in one scene and attempting to understand a classroom assignment in the next.
CUE has not yet been formally reconfirmed for Season 2.
Hiro Kaburagi Supervised the First Season
Hiro Kaburagi served as animation supervisor and handled series composition for the first season.
Yasunori Ide worked as animation director, while Miho Daidoji designed the characters.
Their work established the television adaptation’s balance of deadpan comedy, youthful character acting and sudden professional violence.
The Season 2 announcement did not include a returning staff list, so their continued participation has not yet been confirmed.

aespa and RIIZE Performed the First-Season Themes
The opening theme for the first season was “ATTITUDE”, performed by aespa.
RIIZE performed the ending theme “KILL SHOT.”
The two globally recognized groups gave the anime a strong musical identity during its first television run.
Season 2 has not yet announced whether either performer will return or whether the continuation will introduce completely new opening and ending songs.
What Could Season 2 Explore?
The second season can continue Juzo’s investigation into the mysterious wasp and the technology responsible for changing his body.
His mission is becoming increasingly complicated because the people he originally viewed only as sources of information have become genuine friends.
Returning to his adult body remains an important objective, but doing so may eventually require him to abandon the school life he has started to value.
New assassins and organizations can also pursue the secrets held by Mitsuoka Pharmaceuticals, placing Noren and the other students in greater danger.
The production has not officially identified the manga chapters or story arcs planned for Season 2, so detailed adaptation predictions remain speculative.
Juzo’s School Life Is More Than a Disguise
Juzo initially enters school because it is part of an assignment.
Over time, however, the experience becomes something more personal. He receives opportunities to make friends, join activities and participate in a form of youth that his violent career never allowed him to enjoy.
This emotional development gives the story more depth than a simple comedy about an adult trapped in a younger body.
Juzo may still describe himself as a professional completing a mission, but his decisions increasingly reveal how much he cares about the students around him.
Based on the Manga by Tadatoshi Fujimaki
KILL BLUE is based on the manga written and illustrated by Tadatoshi Fujimaki, the creator of Kuroko’s Basketball.
The series began serialization in Weekly Shonen Jump in April 2023.
Its combination of assassin action, school comedy and an adult protagonist experiencing adolescence for a second time gave the manga a distinctive identity within the magazine.
The original manga has concluded, meaning the anime has a complete story available for future adaptation.
What Remains Unknown About Season 2?
KILL BLUE Season 2 currently has no announced release date or premiere window.
The episode count and Japanese television schedule remain unknown.
CUE and the first-season staff have not yet been formally reconfirmed.
The returning Japanese and international voice casts have also not been announced.
No trailer, official Season 2 key visual, synopsis or theme-song information has been released.
International streaming plans remain unconfirmed, even though Crunchyroll and several other services carried the first season in supported territories.
Final Thoughts
KILL BLUE Season 2 is officially in production following the conclusion of the anime’s 12-episode first season.
The sequel was announced on June 27, 2026, immediately after the broadcast of Episode 12 in Japan.
Tadatoshi Fujimaki celebrated the news with an original illustration showing Juzo firing a handgun while holding a textbook, capturing the combination of assassin action and school comedy at the center of the series.
The continuation currently has no premiere date, episode count, trailer or confirmed streaming platform.
The returning studio, staff and cast also remain unannounced.
With Juzo becoming increasingly attached to the school life that began as nothing more than another mission, Season 2 can continue exploring whether the legendary assassin truly wants to return completely to the man he was before the mysterious wasp gave him an unexpected second youth.
