Kizuna AI Desktop Mate DLC Launches on Her Birthday
The release on Kizuna AI's birthday and the involvement of her own company in motion production signal a deeper integration of the virtual talent's brand into the desktop mascot market, rather than a simple licensing deal.
Reporting from 3 sources: Denfaminicogamer, GIGAZINE, PANORA.
Infinite Loop Co., Ltd. released the Desktop Mate Kizuna AI DLC on June 30, 2026, which is also Kizuna AI's birthday. The paid DLC, priced at 2,200 yen, is available on Steam for Windows and macOS. It includes the largest number of motions of any Desktop Mate DLC to date, with all animations produced by Kizuna AI Inc. The DLC reproduces Kizuna AI's signature greeting "Hai Doumo!" and features different reactions for standing and sitting poses, along with emotional expressions for interactions like petting, poking, and the alarm function. The alarm notifies the user with a pop-up and a spoken time announcement in a casual format rather than a strict clock reading. The base Desktop Mate app is free, and the DLC requires it. The macOS version entered open beta on June 24, 2026, and supports Apple Silicon chips.
GIGAZINE tested the DLC on a PC and described the setup process. After launching the free Desktop Mate base app, the default character Aierutan appears. Right-clicking Aierutan and selecting "Change Character" lets the user switch to Kizuna AI if the DLC is purchased. The size can be adjusted in 100 steps from 1 to 100. At size 1 the character is a small figure in the bottom-right corner; at size 100 it becomes quite large.
The review noted specific behaviors. Kizuna AI follows the mouse pointer with her eyes, sits on the taskbar or windows, and reacts happily when petted. She responds with voice when clicked. The alarm function triggers a pop-up with an electronic "popopon" sound and announces the time in a casual format such as "It's time~" rather than a strict clock reading. Multiple alarm motions and voice lines are prepared and switch randomly.
Denfaminicogamer and PANORA both reported that the DLC includes the largest number of motions of any Desktop Mate DLC to date. All motions were produced by Kizuna AI Inc. The emotional expressions switch among states including "joy," "panic," and "pride" during interactions like petting, poking, and the alarm.
The macOS open beta began on June 24, 2026, and supports Apple Silicon chips only. Desktop Mate reached 2 million total downloads as of that date, and voice support was added to the default character Aierutan, meaning all characters now have voice.
