Definitely Ichigo, followed closely by Aoi. I always love Yurika's performances, also Seira and Juri. I had a soft spot for Hikari from the first season too - she had barely any screentime but I liked what we did see of her. And of course Splash are wonderful <3

I'm currently watching the second season of AikaStars, it's not as good as original Aikatsu but it's still enjoyable. I like that the writers actually tried to introduce romance into the show, although still not very well lol. *still wishes something had happened between Ichigo/Naoto, or at least Akari/Sena*
