I don't know why but Cure Wink's Wink Crescendo just tickles my brain. No joke, I listened to it for like 20 minutes on loop.
haven't watched them all yet so i've a limited roster to choose from (finished 2004, 2005, 2010, and everything from 2016 to 2024 (minus Kibou no Chikara which was the first adult Precures series), and currently watching 2006 (splash star) and 2015 (go! princess)
