The 22/7 idol group performs the anime’s opening theme song “Muzui” (Difficult) and ending theme song “Sora no Emerald” (Emerald of the Sky).
Idol group members Mizuha Kuraoka and Urara Takatsuji are both also taking a hiatus from the group for health reasons.
The “Aniplex 48-hour TV” livestream on the AbemaTV streaming service announced on Sunday a new “rival unit” for the 22/7 idol franchise.
The group based on the concept of “idols who cross dimensions” has eight anime idol characters, with their respective voice actresses performing as idols in the real world.
