i dont know about this one as i cant find much about it other than personal accounts and most of them are repeated, would love to watch the youtube videos but i'm afraid i'm gonna have to wait a few hours till i finish work as my company has banned youtube
also it seems it has a connection with jimmy paige (the guitarist of led zeppelin if you dont know your music history) he is quoted as it being his own personal demon, also it is written on the cover of their 4th (runes) album.
Oh yeah that was MitsuX's thread. She apparently challenged Zozo after getting it on the board only a month after she joined in 2010. She would post every now and then proudly saying that she is still alive. One month after she challenged ZoZo, she vanished from UM. I hope she's ok. To be honest, I wouldn't challenge any demon openly, especially Mr Z.
