This episode is the start of the Kanya Fest arc. It isn’t a puzzle this time but a challenge for the Classics Club. It's hard to believe that this is a 14 year old anime, the OP animation and some of the scenes in the episode has more frames than a certain modern anime 😏. Oreki’s sister’s face isn’t fully revealed which is quite intriguing and the pen she gave Oreki seems to have started a chain similar to the Straw Millionaire. I’m really looking forward to seeing what the final trade will be 🤩
