I couldn't find any official track titles, so I made them up.
Haruna Raika is a "super" (as in perfect) grade school student, but in the end, I don't think that fact is all that important. It's more-or-less about everyday lives of grade school kids and some grown ups around them. Perhaps the sugar coating is a bit unrealistically thick, but hey, we can all use some sweet breaks, along with some hot cocoa, from the real world.
I learned about this drama CD on Raika Days internet radio (Hibiki-Radio.jp). I've been focusing too much on radio CDs lately that I forgot how much I love audio dramas. Although the Raika Days radio only lasted 6 broadcasts, they're promising new THREE ARROWS radio, so I look forward to supporting them with additional drama CD purchases.
