Lapis Live (a subsidiary of AI, Inc.) has launched a collaboration event titled “Strongest Alliance Campaign” with the mobile game “Doomsday: Last Survivor,” starting August 19, 2026. Nine of its affiliated livers are competing in a points-based battle, and listeners can directly support their favorite liver by joining their in-game alliance.

Event Overview

“Doomsday: Last Survivor” is a mobile game set in a near-future world overrun by zombies, where players build and expand shelters (headquarters) to fight back. In this collaboration, nine Lapis Live livers compete against each other to accumulate the most points by September 19. The liver with the highest score wins and earns the right to have a dream fulfilled.

Since the number of participants in each liver\’s alliance (guild) directly contributes to their points and power, listeners can directly support their favorite liver by joining that liver\’s alliance. The process involves visiting the event page, downloading the game through the preferred liver\’s link, and filling out a dedicated form to join the alliance.

The Nine Competing Livers

The nine participants are Amagami Bibi, Yumehime Yomogi, Haise, Luna Viole, Shunkashuutou Kimera, Kanano Ito, Oozora Hinata, Seikimatsu Rabu, and Rumio Lumina. All of them are active on IRIAM, a V-live communication app, and plan to livestream gameplay commentary during the collaboration period. Listeners can tune into their IRIAM audio streams while playing in the same alliance, creating a truly interactive experience between livers and fans.

About Lapis Live

Lapis Live is a liver management agency that has signed an organizer agreement with IRIAM (operated by DeNA Group company IRIAM, Inc.). Founded in August 2021, it became part of the AI, Inc. (Securities Code: 4388) group in April 2025. With over 400 affiliated livers, the agency operates under the motto “Bringing you brilliance like precious gems.”

Looking Ahead

The collaboration period spans approximately one month (until September 19 at 18:00 JST), long enough to generate interest in ranking shifts and progress updates. Collaborative events linking livers and games are gaining traction across the industry as a new model for revenue generation and fan engagement, making Lapis Live\’s future initiatives worth watching.

Our Take

Having livers lead in-game alliances where listeners can actually play alongside them elevates this beyond a simple promotion into genuine “participatory content.” The design benefits all three parties: the game publisher gains new users, livers gain fresh touchpoints with fans, and listeners get a direct way to support their favorites. With a month-long collaboration period, it will be interesting to see how much momentum this event builds.
