It seems there was at one point a bassist named Shigeki (刺激) and later a bassist named Ayaka (彩嘩), although they both seem to have seceded(?) by the group's disbandment. Further details are unknown; they might be the same person.

There was also a bassist named Shigeki (刺激) in the band Sarieli, but it's unclear if that's the same person as was in this band.
