Bridal Bigsuri's getting decent traction, probably about as popular as Bridal Nano now, who's probably only the second most popular of the brides due to close NanoShizu proximity. It feels like Hakari and Karane are last in popularity, how the mighty have fallen, maybe when they can be pulled they might make a comeback.
Say what you will about the gacha, but anything that gives the kanojos fun outfits and inspires more fanart can't be all bad.
