The CD Hunting lists five members: V. Nana (なな), G. Shuu (朱羽), G. Bouka (業火), B. Aki (あき), and an unknown drummer (his name is obscured in the only image we have of the release).

According to the vocalist of Nihon Kinodoku Uta Gekidan (日本気の毒歌劇団), the guitarist of that band, Masato (雅兎), was also in Yamineko (闇猫). However, it's unclear if he is the same person as guitarist Shuu (朱羽) or Bouka (業火), or if he was an earlier/later member. Details are unclear.
