I just finished making the page of the mysterious producer, XYXYZ. Researching about this producer is something and led me into a rabbit hole of mysteries.
When I was writing the description about this producer, I was wondering if I should include the mysteries. But I realized this is Vocaloid Wiki, and anything about the mysteries becomes off-topic so I did my best to write a description that is only Vocaloid-specific.
I wanted to talk about this mysterious producer more, but I have to rest first since I'm going to be a bit busy in real life. I'm planning to continue discussing this on my next blog if I have time.
