about Kanariya and HANABI

[Yukitora]

Well, every other song title has been english... maybe she didn't want kanariya and hanabi to be odd ones out.

However I heard that the song would lose meaning if it was translated into english (fireworks) or kept in Japanese characters. That hanabi rather was a word that was something beautiful for a very short time, but died almost instantly. Not the literal 'fireworks' which kinda of give off the feeling of joy instead.
