The Visualize West omnibus gives a five-member lineup for the band, but shows only two members. This lines up with online sources that list only vocalist Shota (将太) [or Shou (将)] and guitarist Ken (喧).
I would consider the five-member lineup completely erroneous except for the fact that it mentions a bassist Sho~ta, which is consistent with the two-member lineup. It seems that perhaps all members except Sho~ta seceded, and that he changed his name and position, and then recruited guitarist Ken (喧).
Details are unclear/unconfirmed.
V. AKI (アキ) / G. Yuuki (悠稀) / G. Reika (麗茄) / B. Sho~ta / D. Kyoura (狂螺)
