It is confirmed that the guitarist of the band was previously in OCTPASS, but it is unclear which. Based on the timeline, it makes the most sense that it's MASA from OCTPASS, but this is unconfirmed.

Additionally, the support bassist is listed only as “mysterious super-talented bassist” (謎の激ウマベーシスト).

The entire reason for the band's existence, as confirmed by SSKANON, was to spite the other members of OCTPASS, who continued on in the band while he was in the hospital.
