YEAH! Episode #60 for Chanchaka Charmy!! And still going strong
Rika mentioned Nono's and Yu-chan's birthdays at the end of the show. So maybe they're her guests!!!
There's Ishishiba and Rikamiki stuff in this ep. Rika says that the members gave her grad presents and Miki's was a pair of socks with her own drawing on them. (Miki's drawing :| ) Don't know what else she says but she's laughing her ass off when talking about this.
(OT, but I also heard that Miki went to see vi-yu-den concerts both days!!) And about Ishishiba... Rika says that she was
very nervous before vi-yu-den concert started, so she called Shiba-chan. And she cried just when she heard Shiba-chan's voice.

That's all I can remember. Correct me if I'm wrong coz I only listened to the show once and haven't d/l-ed it yet.
