The studio really did splurged on this episode, they have gone beyond in art and animation. The scene at 15:21 reminded me of the style used in My Dress up Darling S2, where real world scenery is combined with drawn characters. However, upon closer inspection the scene was incredibly well drawn and almost realistic 😯. Oreki blue-balled us at the end there, I really thought that he did it so naturally unlike with Fukube. I hate it when a show ends this way, and the worst part is that there is no chance of a season 2 for this exceptional anime. 😭
