How much demand would there be for a RESCENE concert?

For high-priced offline demand like concerts, the ratio of hardcore fans versus casual listeners is more important than the total number of casuals, and generally, non-fans don't attend idol concerts much (they tend to go to concerts by highly skilled vocalists more often).
However, given this level of buzz, I think they could probably fill about 5,000 seats for two days if they held it right now.
Of course, right now it feels more like "YouTube views > singer RESCENE," so I think having a hit song will be even more important moving forward.
