Square Enix recently hosted its NieR 15th Anniversary Livestream, unveiling a series of upcoming events and updates to honor the beloved franchise. Discover what’s in store for fans across multiple mediums, including the latest from Re[in]carnation’s monthly developer blog.

To mark the 15th anniversary of the NieR series, Square Enix rolled out a range of exciting announcements during its livestream event on April 19. Among the highlights was the reveal of [U]ndecided Option, a special online novel created exclusively for the anniversary celebration.
The online novel will be released in three parts, with the first update already live. The second and third installments are scheduled for release on April 25 and May 2, respectively. A brief synopsis teases: “Such a 'servant' meets a mysterious boy with a mysterious air and is guided.”
In addition, Square Enix launched an official NieR 15th Anniversary website, which serves as the central hub for accessing the online novel and other upcoming anniversary-related projects and events.
As part of the anniversary festivities, Square Enix is planning a special exhibition at Sunshine City in Ikebukuro, Japan. This event will showcase exclusive new artwork featuring protagonists from Replicant, Automata, and Re[in]carnation. Further details regarding tickets and event dates will be shared at a later time.
Fans can also look forward to additional performances at the NieR: Orchestra Concert 12024. New dates have been confirmed for Osaka (July 25–26) and Tokyo (August 2–3). Tickets are now available through a lottery system—visit the concert’s official site for more information.
On the merchandise front, several exciting products are in the works, including:

Marking another milestone in the anniversary lineup, NieR Re[in]carnation—the franchise’s first mobile title—will debut a monthly developer blog series starting April 28. These behind-the-scenes updates will continue throughout the year, offering fans an inside look into the game’s development process.
Originally launched in January 2021, Re[in]carnation concluded service in April 2024 due to monetization challenges. The sudden announcement of a developer blog for a now-closed title has sparked curiosity among fans. Speculation is growing that this could hint at a potential sequel or remake, although no official statement has been made yet.
The livestream wrapped up with a 20+ minute live performance showcasing memorable soundtracks from across the NieR series. With even more events, content, and merchandise on the horizon, Square Enix continues to deliver unforgettable experiences for NieR fans worldwide.
Stay tuned for future updates as the celebration unfolds across games, music, literature, and beyond.
