Following the 19th birthday of Vocaloid characters Kagamine Len and Rin, the twins will join Desktop Mate as DLC. Each of them currently have a January 2026 release window, though there’s no exact release date for either one’s release. However, the product pages for Len and Rin and live for wishlisting now. Each one will cost ¥2,200 after launch, which means they should cost around $14.99 each. There’s no word about a bundle with the two together.
Crypton Future Media made the 3D models for both the Kagamine Len and Rin DLC packs. Infiniteloop worked on the animations. If someone owns the add-ons for both characters, they can be linked together for combination animations. Some of the examples included both appearing when an alarm goes off, rather than just one, or them reacting to the other’s animations and behaviors.
Here are the initial screenshots showing Kagamine Len in the app.





And here’s how Kagamine Rin looks in Desktop Mate.





A number of other Crypton Vocaloids, and spin-offs of them, already appeared as DLC for Desktop Mate. Hatsune Miku was the first add-on. The 2025 version of Snow Miku, the Magical Mirai 2025 Miku, Kasane Teto, and Megurine Luka showed up after that.
Desktop Mate is available for PCs, and the Kagamine Len and Rin DLC will debut in January 2026.
