Japanator: "Just like every anime series apparently has a beach/hot springs episode, this one finds the cast hanging out at an indoor water park. It just so happens that the purple-haired girl I've been asking about for a couple weeks now has a name: Neko. Her parents must really like cats, or maybe that's a nickname. In any case, it appeared she could see Hiyori in the episodes she's turned up in, as well as earlier in the series. I'd also be willing to bet that big sister Yuki can see Hiyori as well, especially if the conversation at the beginning of this episode is any indication."
