As part of the 20th-anniversary project for the Sister Princess franchise, three sisters have made their virtual YouTuber debut since last September.
Also, the 20th-anniversary project plans to launch a crowdfunding campaign to collect funds for a virtual live concert by the five sisters – Karen, Sakuya, Kaho, Mamoru, and Aria.
The schedule for Mamoru and Aria’s virtual YouTuber debut has not yet been finalized.
