Kalma Rock Star Stream Gets First Drama CD With Mafia Drama Twilight Gangsters
The release packages Kalma Rock Star's existing short-form voice content with a new mafia storyline and ties the rollout to an event-only limited edition, which is how the MonSon! music spin-off is being extended past its audio releases, with a promotional video already on the project's YouTube channel.

MIXI announced on October 1, 2026 that Kalma Rock Star Stream Drama CD vol.1 will release for the MonSon! project. It collects seven short voice drama episodes and seven episodes of the new drama Twilight Gangsters, in which the band's four members play members of two rival mafia groups. Advance sales run at Animate Girls Festival 2026 on November 7 and 8 at Ikebukuro Sunshine City.
The project is a spin-off of MonSon!, itself themed on the music of the Monster Strike game app, and is set in MonSon! City. The drama CD carries two editions. The AGF limited edition costs 16,000 yen and pairs the disc with a tote bag, a B2 item picked per member, a newly drawn mini colored paper, and an acrylic stand. The regular edition costs 2,900 yen and adds a replacement jacket-style postcard. Both share the same recorded content.
