Great episode. It made like Cryska a lot more; I'm quite fond of her calm demeanor. Yuuya's dense, but I still can't help but like him as the protagonist.
And Yui proves to be as adorable as ever with all her blushing. The ending was spectacular in that regard. And pretty hilarious, too. Seeing her get all hot and bothered by being seen by Yuuya in her bikini is just too much!
