NieR 15th Anniversary Livestream Highlights

Square Enix Announces NieR 15th Anniversary Special Novel

As part of the NieR 15th Anniversary celebrations, Square Enix announced a new online special novel titled [U]ndecided Option. The novel launched during the April 19 livestream and will be released in three parts, with the first update already available. The second and third installments are scheduled for April 25 and May 2, respectively.

The story follows a mysterious narrative thread: “Such a 'servant' meets a boy with an enigmatic presence and is guided.” This unique addition expands the lore of the NieR universe and offers fans a deeper dive into its rich storytelling.

Additionally, Square Enix launched a dedicated NieR 15th Anniversary website, serving as the central hub for accessing the online novel and staying updated on all related events and projects throughout the celebration.

Exhibition, Concerts, Merchandise, and More

A special exhibition event is set to take place at Sunshine City in Ikebukuro, Japan, showcasing exclusive new artwork featuring protagonists from Replicant, Automata, and Re[in]carnation. Further details regarding ticket availability and event specifics will be shared at a later date.

Fans can also look forward to the NieR: Orchestra Concert 12024, with performances scheduled in Osaka (July 25–26) and Tokyo (August 2–3). Tickets are currently available through a lottery system—more information can be found on the concert's official site.

On the merchandise front, several new products were unveiled:

• NieR Dinner Show – Somethin’ or Other 12024: A studio jazz arrangement album set for release in December 2024.
• NieR Weapon Story Book: A comprehensive collection featuring over 650 stories behind the weapons seen across Replicant, Automata, and Re[in]carnation.
• Scale Figures: Highly-detailed collectible figures of key characters from the NieR series.

Re[in]carnation Developer Blog Series Launches April 28

Marking another milestone in the anniversary festivities, NieR Re[in]carnation—the series’ first mobile title—will debut a monthly developer blog starting April 28. These behind-the-scenes updates will continue throughout the year, offering insight into the creative process behind the game.

Originally released in January 2021, Re[in]carnation was shut down in April 2024 due to monetization challenges. Its sudden discontinuation left many fans curious, especially in light of this new blog initiative. Speculation has since grown around the possibility of a sequel or remake, though no official confirmation has been made yet.

The livestream concluded with over 20 minutes of live musical performances featuring iconic soundtracks from across the NieR series. With more events and merchandise still to come, Square Enix continues to deliver unforgettable experiences for NieR fans worldwide.

Stay tuned for future announcements and updates as the celebration unfolds.
