Stargazing: Kuchibue Jet - Hanazawa Kana
Day 5 arrives with my favourite seiyu of all time. Don't give me that look, it's most unlikely that this fact will ever change. With that said, let's move on to the song of the day!
Kami Nomi zo Shiru Sekai was a strange series filled with some good romance, comedy and character development. One of its best strengths however, was its ability to meld amazing seiyu with even more amazing music. Such is the case with Hanazawa Kana and 'Kuchibue Jet', the character song for her character.
I stumbled across this song much later, and it was actually one of the factors that played into me picking up the series to begin with. It's got a wonderful melody backed by one of the cutest voices you will ever hear in anime, and I just can't get enough of it.
