Sawai Natsumi (沢井なつ美) was the guest for the 25th broadcast. It was recorded at an okonomiyaki store. The reason Natsumi was a guest was because Natsumi was going to be the guest host this month. (Rieko wouldn't be able to attend the Idol 109 public recording, so Natsumi was going to fill in.)

They just talked while they ate and drank. Rieko did the cooking. (^_^; Noa said she only drank orange juice, but she might have been drinking something else..

At the beginning, they were talking about the Idol 109 event, but after a while the talk just went onto many other topics.
