based on weiss schwarz collector AGR rares (personally signed, not stamed, limited amount) prices, the cheapest cards and therefore the least popular idols are mao, sumika, and china at 128k yen. sumika's the 3rd no image one because おいしい顔、いただきー!is her card.

nah I don't want that much more idols to produce. if we start going off the rails producing 50+ idols I'ma lose interest. we have 13 right now, keep it at a tight 15 with rinha and tsubame or jump to like 20 max.
