Nijisanji and karaoke chain “Karaoke Manekineko,” operated by Koshidaka Holdings Co., Ltd., have launched their collaboration campaign “Nijisanji x Manekineko Sweet Scoop Sundae” at participating locations nationwide starting July 15, 2026 at 1:00 PM. Newly commissioned visuals themed around an “ice cream parlor” have been revealed.

Ice Cream Parlor-Themed Newly Commissioned Visuals

This collaboration features newly commissioned visuals with a summer-perfect “ice cream parlor” theme, showcasing four Nijisanji Livers: Joe Rikiichi, Hanabatake Chaika, Mashiro Meme, and Ryushen. Against the backdrop of an expected heat wave this summer, the campaign offers a special entertainment experience combining exclusive menu items in the cool, private comfort of karaoke rooms.

This follows the Nijisanji 8th anniversary collaboration with Manekineko in May, continuing the partnership between the two brands.

Collab Drinks, Dessert, and Limited-Edition Merchandise

The collab menu features five original drinks (700 yen each, tax included), each inspired by a participating Liver, plus one dessert — the “Coconut Malasada Ice Cream Sandwich (Chocolate)” (900 yen, tax included). Each drink purchase earns one random limited-edition postcard, while each dessert purchase earns two.

Merchandise includes acrylic stands (1,870 yen), acrylic keychains (880 yen), hologram sticker sets (990 yen), square can badge sets (1,500 yen), square cards (440 yen), and more. Items are also available for online purchase through the official Manekineko online shop.

Collab Rooms at 7 Locations and Singing Campaign

Seven locations nationwide — Sapporo Ekimae, Ikebukuro Sunshine-dori, Yokohama Nishiguchi, Meieki Yonchome, Nankai-dori, Kawaramachi Takoyakushi, and Hakata Ekimae — will feature dedicated collab rooms with standing panels. Reservations can be made through the collab room reservation site.

Additionally, a singing campaign rewards participants with exclusive digital wallpapers — sing a designated song by a participating Liver on a compatible karaoke machine, and receive the wallpaper instantly.

Future Plans

The campaign runs for approximately one month through August 16, 2026. Online merchandise sales are open until August 16 at 11:59 PM. Nijisanji and Karaoke Manekineko have been running collaborations on a regular basis, and further joint events are expected going forward.

Commentary

Nijisanji and Karaoke Manekineko have partnered multiple times this year, demonstrating strong synergy between the two brands. The “ice cream parlor” theme is well-suited for summer foot traffic, and the tie-in with collab drinks and desserts is smartly executed. The addition of a singing campaign that leverages karaoke’s core appeal on top of the seven collab room locations is also noteworthy. As a model for cross-industry VTuber x karaoke chain collaborations, future developments are worth watching.
