Koshidaka Corporation has launched a collaboration campaign with VTuber Kurageu Roa at “Karaoke Manekineko,” which operates 719 locations nationwide, starting August 20, 2026 (Thursday). The campaign features limited original goods and collaboration drinks under the “ROA’S DINER” theme.

Limited Goods with the “ROA’S DINER” Theme

The collaboration features original merchandise showcasing limited illustrations of Kurageu Roa dressed in diner attire. The lineup includes acrylic stands (2 types, 1,800 yen each), acrylic keychains (2 types, 1,000 yen each), pin badge sets (2 types, 1,200 yen each), random die-cut stickers (6 types, 660 yen each), a case with photo-style card set (1,600 yen), and record coasters (4 types, 1,500 yen each) — 8 types in total.

Additionally, EC-exclusive items including a plate (3,500 yen) and glass (3,000 yen) are available. After the collaboration period, goods are also scheduled for sale at the Karel Online Store.

Three Summer-Perfect Collaboration Drinks

Three colorful non-alcoholic drinks inspired by Kurageu Roa are also being offered: “Summer Sea Cider with Roa,” “Deep Sea Grape Soda,” and “Absolutely Angelic Roa-chan!” — each priced at 700 yen (tax included). A limited-edition coaster (6 random types) is included as a gift with each drink order.

Participating Locations and Special Website

The campaign is being held at Karaoke Manekineko locations nationwide, with participating store details available on the special campaign website. The campaign runs from August 20, 2026 (Thursday) at 1:00 PM through September 23 (Wednesday).

Future Plans

Karaoke Manekineko has been building a track record of VTuber collaborations, leveraging its nationwide network of 719 stores to create real-world touchpoints between VTubers and fans. Operating under the concept of “Entertainment as Infrastructure” with locations in four countries overseas, Manekineko is expected to continue VTuber collaborations as part of this broader vision.

Commentary

While karaoke chain and VTuber collaborations are becoming a staple, the “ROA’S DINER” theme is a clever fit for Kurageu Roa’s aesthetic. The cohesive concept — from diner-outfit illustrations to record coasters — creates a unified visual experience with strong collector appeal. The nationwide reach of a major karaoke chain is also poised to help expand the VTuber fan base to broader audiences.
