-For girl groups, I'd say 4 members. For boy groups, I'd say 7 members.
-7! It'd make a beautiful stage formation, plus you can play mafia game~~
-5 to 7 members
-The ideal number is 7. But I personally like it when an idol group consists of 5 members.
-7 to 9 members, I think??
-7 to 9 members. But the more members they have, the more I like it. It'd be really fun at concerts!
-For girl groups, I think it's 4 to 6 members
-5. I think 5 members is the best for idol groups.
-5 members are the most ideal, but the absence of one member will really be noticeable. So I'd say 6 or 7 members
-9 members or more. It'd be fun to see them performing...
-23 members<3 But if we're talking about idol groups in general, I think it's 7 to 9 members
-5, I think...? I don't really like groups with large numbers of members...
