  • The group was originally supposed to feature 8 characters but was expanded to 11 shortly before the group debuted. Due to this, early activities of the group only included the eight characters that were voiced. The 11 member character line-up fully debuted in their fourth single. The Seiyuu who didn't have characters that were voiced still participated in activities alongside the group and released the same promotional material as the other members and are considered to have participated in the first three releases.
  • The group was originally formed with 12 members, however the twelfth member did not end up debuting with the group for reasons unknown.
