@estherchan: Gazatte's first drummer was called Yune (ユネ)
Ruki's had many names in his past, he still uses one of them for crediting himself for lyrics (on the Disorder, NIL and STACKED RUBBISH lyrics credits you'll see 流鬼 instead of Ruki.)
In the past he was known as Kaede (楓)...I think that was back when he was the drummer in Mikoto.
He was called Seizen (切茜) back when he was part of Kar+te=zyAnose (and that was when he first became a vocalist~)
He's had some odd names o_o;; ...
Aoi used to go by the name Natsume (棗) back when he was in Artia
