Episode 20 is up for download at CLAMP no Kyoto Agaru Sagaru‘s official website.
They started the show reading a message from a listener talking about the “Syaomatsu-san” drawing that they did for Episode #17.
Then, they celebrated Satsuki Igarashi’s birthday (Feb. 8). (That’s not very fair since they didn’t mention anything for Nekoi’s birthday in January =P)
Some more seiyuu talk… some more “Syaomatsu” talk…
Then, they moved the conversation to detective stories (they played the CLAMP Gakuen Tanteidan TV anime opening theme song, Peony Pink by ALI PROJECT, but that is not included in the podcast, as usual). Ohkawa is a big fan of detective stories as you may know, so she asks the others what and theirs. Mokona answers that she likes the “Mitarai” series, by Soji Shimada. I couldn’t understand the other members’ favorites because it’s all Japanese works.
They spent the rest of the episode talking about detective novels and their movie/drama adaptations.
