Episode 13 is up for download at CLAMP no Kyoto Agaru Sagaru‘s official website.
This episode’s guest was seiyuu and singer Iwao Junko. They basically interviewed her about her career as voice actress and singer (she has such a soothing voice!).
Here’s a picture taken by CLAMP of Iwao Junko in KBS’s radio studio:
