I recently watched the anime Cross Ange and I was curious about the phrase "Lulala lila" which is sung in the song Hikari no Uta. I'm pretty sure that phrase means something, but I still don't know what it is.
The phrase "Lulala lila" is not in Japanese and the word "Lila" means something divine in Hinduism. I just can't find the meaning of "Lulala" to understand the meaning of "Lulala lila" sung in the song.
This is a part of the lyrics of the song:
Hajimari no hikari kirali... kirali Owari no hikari lulala lila Kaesan El Ragna Suna dokei wo Toki wa afuren Lulala lila
