Bungo Stray Dogs: Tales of the Lost Ends Service on July 31 After 8 Years, Company Closure

Bungo Stray Dogs: Tales of the Lost will end service on July 31, 2026, one day after the announcement was made. Ambition Co., Ltd., the company operating the game, is closing down, leaving no option to continue the service. The game has been available for nearly 8 years since its global launch on July 4, 2018.

"We regret to announce that service for 'Bungo Stray Dogs: Tales of the Lost' will end on Friday, July 31, 2026. Unfortunately, we have decided to end the service, due to the closure of Ambition Co., Ltd., the company operating this app." (Official website notice, July 30, 2026)

Official Announcement

The official English X account for the game posted the End of Service notice on July 30 at 04:06 UTC, with a thread detailing the terms. The announcement states that no refunds will be issued for unused Ability Stones, citing Article 14, Paragraph 1 of the Terms of Service. The account also noted that rights holders and affiliated companies are not responsible for the operation of the app, directing users to refrain from contacting them.

The one-day notice effectively leaves current players with less than 24 hours to spend any remaining premium currency, complete unfinished content, or say goodbye to their accounts.

Background: What Was Bungo Stray Dogs: Tales of the Lost?

Bungo Stray Dogs: Tales of the Lost (also known as Bungo Mayoi in Japan, from the Japanese title Bungo Stray Dogs: Mayoi Inu Kaikitan) was the first mobile game based on the hit anime and manga series Bungo Stray Dogs by Kafka Asagiri and Sango Harukawa. Developed and operated by Ambition Co., Ltd., the game was released in Japan on December 14, 2017, followed by a global English launch on July 4, 2018.

The game featured an "Ability Fling" puzzle mechanic where players pulled and released to launch attacks, combined with a gacha system for collecting characters from the Armed Detective Agency, Port Mafia, and other factions. It included game-original scenarios and side stories not told in the anime, alongside the main canonical storyline. Original voice acting from the anime cast (including Yuto Uemura as Atsushi, Mamoru Miyano as Dazai, and Kensho Ono as Akutagawa) was a core feature.

Key Milestones

What This Means for Players

The one-day notice is extremely short by industry standards. Most gacha games announce service termination 30 to 90 days in advance, giving players time to use up premium currency and enjoy final events. A single-day warning is more typical of emergency shutdowns or company closures where no wind-down period is possible.

Players who have spent money on Ability Stones (the game's premium currency) will not receive refunds for unused balances, per the Terms of Service. The game had a 4.6-star rating on Google Play with over 36,400 reviews, indicating a dedicated player base that now faces a sudden loss of access.

The closure of Ambition Co., Ltd. itself suggests the company is ceasing all operations entirely, not just this game. No successor company or transfer of operations has been announced. The rights holders (KADOKAWA, the Bungo Stray Dogs Partners) are explicitly not responsible for the app's operation.

Context: A Pattern of Sudden Shutdowns

July 2026 has seen multiple gacha game closures announced with minimal notice. Ash Echoes SEA shut down on July 24 with approximately two days' notice. Looney Tunes World of Mayhem announced an October 15 closure but gave players two months of warning. Jump + Jumble Rush ends on September 17 with nearly two months of notice.

The one-day announcement for Bungo Stray Dogs: Tales of the Lost is the shortest notice period of any gacha game closure this year. The company closure context explains the compressed timeline: Ambition Co., Ltd. is shutting down entirely, leaving no operational capacity to maintain the game servers past July 31.

What Comes Next

The game will be delisted from the App Store and Google Play after service ends on July 31, 2026. No offline version, companion server, or data migration option has been announced. Players who want to save screenshots, account records, or memories of their in-game teams have until the end of July 31 to do so.

For fans of the Bungo Stray Dogs IP, the anime continues to run with new seasons, and several other mobile games based on the franchise have existed in the past. No new Bungo Stray Dogs game title has been announced as of this writing.
