Yeah seem like in AiFure maybe we will see more couple performance other than solo performance. And for coords in key visual, the coords that Aine and Mio wore is Friends Coord, and the school coords is the coord that Aine wore on idol card because it looks similar to Maika and Ema's Coord. For Karen and Mirai, they wore Best Friends Coord, if I can say Friends Coord has same rarity as Rare Coord and Best Friends Coors has same rarity as Premium Rare Coord but Friend Coord supposed to be used for couple (Aine and Mio, Karen and Mirai).

Yeah in AiFure they add cosmetic on accessory, it can be used during performance, it seems the cosmetic help to maximize the appeal.
