Blue Archive has rolled out one of its biggest content drops of the year. NEXON's anime-styled tactical RPG pushed its EX. Decagrammaton Chapter 3 update live on May 27, 2026 across both mobile and Steam, headlined by a meaty new event story and a fresh wave of unique students to recruit.
The centerpiece is the event story "EX. Decagrammaton Chapter 3, The Sky of Unity Part 2" (Episode 10), which keeps pushing one of the game's most ambitious arcs forward. This chapter hands the spotlight to students from Millennium Science School's Game Development Department and the Super Phenomenon Task Force — including Kei, Rio and Aris — as they band together against the forces of Decagrammaton on the Steel Continent in a high-stakes bid to stop the impending doom of Kivotos.
New students take up arms
As is tradition for a major Blue Archive update, the chapter arrives with a batch of new and reimagined students. This wave puts the focus on combat-ready "Armed" variants, with official promotional videos rolling out for Rio (Armed), Himari (Armed) and a 1-star Toki (Armed) — giving commanders new tactical options to chase down across the banners.
Anniversary build-up and livestream rewards
The update also gets a head start on celebrations, opening pre-registration gifts tied to the game's upcoming 4.5th anniversary and dishing out special reward drops for players who tune into the official Blue Archive livestreams. It's a familiar pattern for the long-running title, which keeps a steady drumbeat of story, students and freebies to keep its devoted commander base engaged.
The EX. Decagrammaton Chapter 3 update is available now for Blue Archive on iOS, Android and Steam.
