ヒナちゃんとかのんちゃんおたんじょうびおめでとう!!

...or Happy Birthday Hina and Kanon!

Hina is Hinagiku Katsura. A character in the fictional world of Hayate no Gotoku.

Kanon is Kanon Nakagawa. A character in the fictional world of The World God Only Knows.

A uniquely fun thing about Japan, when particular manga, anime or light novels get popular is the eventual creation of drama CDs or more particularly radio broadcasts run by the voice actors and actresses (when the series is an anime). Sure, part of it is marketing and advertising to sell the brand, music and dvd/blu-rays. But they really do like to have fun with it.

Both characters birthdays happen to fall on March 3rd. (I believe that Hina's is intentionally meant to fall on this day, which is also Hina Matsuri) So they decided to put on a live "Happy Birthday" internet radio broadcast, which I was able to enjoy, thanks to Ustream.

It's pretty fun, since you get to hear a little bit more of the personalities that are behind the voices of your favorite characters. They also played music snippets from the series, and had one or two other voice actors/actresses stop by to say hello. (Of course, since my listening comprehension is still a bit limited. I only understand about 10-15% of what's going on. Haha!)
