Kill Blue Confirmed for a Second Season After Its Season 1 Finale

What was announced

The Kill Blue anime is getting a second season. The production confirmed it on June 27, posting a Season 2 announcement to the official @KILLBLUE_PR account moments after the first season's finale aired on TV Tokyo. The reveal arrived with a celebratory hand drawn illustration and a comment from original manga author Tadatoshi Fujimaki, who wrote that the next season would once again be a fun, easygoing Kill Blue. Earlier in the day the same account had teased that a major announcement would follow the final episode.

What we know

For now, the confirmation is exactly that: a second season is in production. The announcement did not include a release window, a platform, or staff and cast details, so a premiere date has not been announced. Cast and staff joined the celebration online, with members of the voice cast and the series' chief character designer noting that work on the second season is underway.

Season 1 ran for 12 episodes, premiering on April 11, 2026 in TV Tokyo's late night Saturday block, and streamed internationally on Crunchyroll. The first season closed with its twelfth episode, titled "Course," the broadcast that immediately preceded the renewal news. The production has not said how much of the manga Season 2 will cover, which staff will return, or where it will stream, so those details remain open until a follow up announcement.

Background

Kill Blue is an action comedy based on Tadatoshi Fujimaki's manga. It follows Juzo Ogami, a legendary hitman who has never failed an assignment until a mysterious wasp sting leaves him trapped in the body of a 13 year old boy. Saddled with a bizarre new order to infiltrate a middle school, the once feared assassin has to juggle the chaos of school life with his deadly work while searching for a way back to his adult form.

That premise, a grown professional killer navigating homeroom and after school clubs, gave the first season its blend of deadpan action and slice of life comedy. Tadatoshi Fujimaki's involvement in the announcement, contributing a new illustration to mark the renewal, signals the manga side's continued backing for the adaptation. A second season gives the series room to keep expanding its cast of classmates and rival operatives, though the production has not yet said which part of the story it will adapt next or when fans can expect it.
