Well, according to the 45 facts list that naoki13 posted the link to, Yana does support the DJ's, but because she has so many aliases, it's possible that she came up with a new one that we don't know about yet. But yeah, it's true those are some of her aliases.
I also remembered, Yana Toboso is also an alias of hers' too. Or so I heard. She doesn't like to use her real name.
@katty,
I heard the same thing as well. Yana Toboso isn't her real name. What I did hear was that Yana is her real first her and Toboso is play-of-word for her first name.
Really, I didn't know Toboso was a play on her first name. I really need to check in more with Baka Updates for more info on my favorite mangakas.. I miss some interesting details.
Hello! I have heard that sensei also write under names such as Yanao Rock and Tahagari Yana, but I couldn't find any Kuroshitsuji doujinshi. Can someone please tell me if Toboso sensei had a Kuroshitsuji doujin hiding somewhere under her belt or it is just in my fantasy? Thank you in advance. :)
