Special recording features Hanazawa Kana. This is the lady who lost(?) Ogura Yui('s love?) to Hidaka Rina, and the two are doing the radio together. In a way, I'm glad Ogura Yui isn't also there, but then, it could get even more interesting if she was there. Volume 2 maybe?
Honestly, I didn't really care for Hidaka Rina at first. I think I got to know her first through dot-i radio. She was the 47th personality (2011-07-05 to 2011-09-27). Lately, though, I'm quite drawn to her. I actually re-listened to most of the dot-i radio recently. You know what? She's really quite cute in her own way. I hope she continues to protect Ogura Yui from Hanazawa Kana and others. w
I never cared for this anime. I think I saw one or two episodes. However, it doesn't matter. This radio CD is highly recommended.
