I'm really glad they finally got to all hang out together. They also get along really well. I find the tsunderes endearing, too. I just really can't get past the episode for its overly borderline explicit scenes. I get it; it's cute, they're all girls, too. But yeah, it doesn't sit comfortably with me since they're middle schoolers. Ignoring that part, I think the episode is really good. They had so much fun, and I also had fun watching them enjoy themselves like normal kids and all that.
