Related with Clockwork Lullaby 1 (sharing part of the lyric and apparently having the same singer in both songs), and later confirmed by the official English title of "Clockwork Lullaby 0", this song seems to be a prequel to the series. The song talks how the singer begun to understand the meaning behind the words. The singer starts singing word with positive meanings such as 'Mother', 'Father', 'Wind', 'Water', 'Dreams' and finally 'Love'. Then the singer declares that with that last word she finally understood the shape of the world, but that she still can't find the word for her feelings. After that, the song changes the background music to a dissonant and darker melody and the singer begins to mention words with negative meanings such as 'Lies', 'Pain', 'Crime', 'Punishment' and finally 'Evil'. Then the singer declares with that last word she becomes aware of the world's darkness and asks which word will be required when she will be cast aside. Despite wishing to never had known the meaning of such dark words, the singer affirms that will continue playing with words. Finally the singer says that she will always continue to be at the side of the person to which the song is dedicated to, teaching them new words.
