Spoiler (mouse over to view)
I don't think Viole is Baam. If you read the author's notes, you'll notice he says this sidestory is nearly over and he'll go back to the main storyline with Baam soon. Besides, Baam wouldn't be part of FUG. Yuri Zahard is part of Walhaiksong (Winged Tree organization), and she told Baam to meet her on floor 77, where their HQ is.
And the girl's name is Rachel/Lahel, depending on how it's translated.
"People don't change, they just give in."
Read manga on: batoto | Kubera is the best. (better translation)
