Episode 28 is up for download at CLAMP no Kyoto Agaru Sagaru‘s official website.
They started the episode reading a message from a long-time fan (they follow CLAMP since RG Veda was being serialized). The person wrote that right now they like Tsubasa and Kurogane, that they were very sad that Nirai Kanai hen was over and they are looking forward to the next story. Ohkawa then mentioned the tankoubon release coming in July and the Playbutton which she’s going to write the script for. She told the listener to look forward to hearing Kurogane in that audio drama. Ohkawa didn’t mention anything about Tsubasa‘s next story.
Next, another message from a different listener, this one wrote about the April Fool’s prank they did in their twitter account — they transformed their twitter account in a fictitious Detective Agency ran by Watanuki. It seems like they planned everything only a day before, on the night of 03/31.
They spent the rest of the episode talking about how fun and hard it was for them to do this prank and all sort of background information about it. They mention something about giving up days off in order to execute the prank (they drew a special illustration for the occasion and password protected it so that you had to solve a puzzle in order to access it)
At the end of the episode, a surprise! The ending narration requesting questions, which is usually narrated in Japanese, was also narrated in English this time! So cool =) Does this mean is OK for them to receive messages in English? Start sending your messages in English, everyone!
