A Strange Takeover on Global Servers
Blue Archive players across the world recently witnessed a strange and unexpected event inside the game. Many players logged in expecting the usual smooth experience but found that one character, Koyuki, had taken over the game. The community now calls this odd situation the “Koyukification.”
During this time, the global servers behaved in unusual ways. Recruitment banners that normally display different characters suddenly showed only Koyuki’s 3D model. Groups of Koyuki filled the cafés, which usually host a mix of students in the game.
Later, the hack replaced them with multiple versions of other students and even Hatsune Miku. Adding to the mischief, it renamed the game’s information page to “nihahaha,” a catchphrase connected with Koyuki’s playful personality.
The situation quickly drew attention because the scale of the odd changes suggested an outside interference. Nexon, the publisher behind Blue Archive, quickly placed the game into emergency maintenance. The servers were taken down for around six hours while the abnormalities were reviewed and corrected.
Investigation Shows No Data Was Stolen
After maintenance was completed, Nexon shared an official notice about the incident. According to the company, the hack was traced to an IP address based in the Netherlands. The unusual nature of the breach suggested that the hacker might also be a Blue Archive fan rather than someone looking to cause serious damage.
A full investigation into the global servers was carried out. Nexon confirmed that no important or sensitive data was touched during the “Koyukification.” This meant that player accounts, game data, and payment information were safe. All of these details are stored in separate databases that are routinely checked by the servers, which prevented them from being affected during the incident.

The hack caused only visual and cosmetic disruptions inside the game. Players saw Koyuki appearing everywhere, but it did not harm accounts, purchases, or gameplay records.
To ensure further protection, Nexon has introduced additional countermeasures that restrict access to the internal workings of the Blue Archive servers. The company also reported the matter to the Korea Internet & Security Agency (KISA). The two are now working closely on another investigation to better understand the source of the breach and strengthen defenses.
Compensation Offered to Players
Because the incident caused an unexpected break in the game, Nexon announced compensation for all global Blue Archive players. Anyone who logs in between September 1 and September 8 at 2:59 pm UTC will receive a special package of rewards.
The package includes one 10-Recruitment Ticket, 500 AP, 150 Tactical Challenge Coins, 3,000 Expert Permits, 300,000 Credit Points, 7 Lesson Tickets, 7 Bounty Tickets, 840 Pyroxenes, and 7 Scrimmage Tickets. These items are meant to make up for the downtime and give players a boost in their progress.

It is also worth noting that while the global version of Blue Archive experienced the Koyukification, the Japanese version of the game was not affected. That version is handled by a different publisher and continued running as normal during the incident.
The strange hack has quickly become a memorable moment within the Blue Archive community. While it disrupted gameplay for a short period, the fact that no private or financial data was touched has come as a relief to many. The unusual takeover has also sparked a wave of conversation among players, who are referring to the event with a mix of humor and curiosity.
