Blue Archive is a tactical role-playing game developed by Nexon Games under its MX Studio branch, published in Japan and China by Yostar and worldwide by Nexon. Every fact here comes from the publisher's release record, read on October 4, 2026. It released in Japan on February 4, 2021 and worldwide on November 8, 2021.
Game Facts
Developer, publisher, release dates, platforms and engine read from the game's public release record on October 4, 2026; setting and premise from the same record's own summary.
Background
Blue Archive released in Japan on February 4, 2021, and worldwide on November 8, 2021 under Nexon with English support. The release record shows a Chinese release on August 3, 2023, a HarmonyOS NEXT build in China on November 8, 2024, and a worldwide Windows release via Steam on July 4, 2025 — four and a half years after the mobile launch.
The Windows release carries a regional carve-out worth noting: the release record states it excludes the Benelux countries, Vietnam, Germany, and the territories Yostar manages.
How the Game Works
Blue Archive takes place in Kivotos, an academic city-state established by the union of thousands of academies. Its citizens are divided into three races: humanoids, a category spanning common humans through to beings resembling angels, demons, elves, bioroids and animal-eared humanoids; intelligent werebeasts; and highly advanced robots with human levels of intelligence and individuality.
Humanoid citizens possess Halos, which make them durable enough to survive gunshots and explosions, and which can only be destroyed by certain means. As a result almost every student carries a firearm, and campus shootouts are a routine feature of the setting.
The city is governed by the General Student Council, a federal committee led by a President who operates from the Sanctum Tower with access to every student's register. The three most powerful schools are Millennium Science School, Trinity General School and Gehenna Academy.
The player is Sensei, a teacher summoned from outside Kivotos by the General Student Council President to advise SCHALE, an extrajudicial organisation she established. She then disappears, criminal activity rises, and Sensei is asked by the remaining council members to resolve the resulting problems while helping search for her. Sensei works with a smart tablet called the Shittim Chest and an assistant program within it named Arona.
That is the limit of the sourced premise.
Official Channels

We link the official site without nofollow because we have opened it and we do stand behind it. Third-party code trackers are cited with nofollow on the codes pages, not here.
Cosplay
Our cosplay column covers one female lead from this game as a costume design study. It is an illustrated entry, not a photograph of a real cosplayer, and we say so on the page itself.
Sunaookami Shiroko
Shiroko is a student of Abydos High School and a member of the Abydos Foreclosure Task Force. Abydos High School is in deep debt, and its five remaining students formed the Task Force to deal with the gangs attacking the school; the group later becomes officially recognised as Abydos' student council.

Update Rule
We do not restamp this page just to look fresh. It records what was checked, when it was checked, and where the evidence runs out. If the publisher's own material changes, this page gets corrected; if we simply have nothing new to add, the date stays where it is.
