The resolution is low and it's not a photo from the main live performance, so I'm posting it here instead of on Twitter.
Even in desktop mode, seeing them moving right in front of me gave a great sense of presence...
I couldn't hear the three of them speak, but I wonder if they were talking about Mururu (the avatar used by B-Stederuminas) that I was using.
Rui's performance and the particles spreading in the space were truly beautiful. The effects that interfered with my field of view were amazing!
I'm glad I was able to watch it even on a low-spec PC.
