It might seem early, but I think it's a good time to start planning a Vocaloid gathering. Black Rock Shooter, UTAUloid, and Kagerou Project cosplayers are also welcome since they have a close connection to Vocaloid.

I'm also looking for a Senbonzakura Luka, and Meiko for a Senbonzakura group. So, if you're interested in doing a Senbonzakura group, let me know also!
Day of Gathering:
Day 2 (6/8) [There will be another gathering on Day 1 for those who cannot make Day 2]
: Red Dock
