This is an AMV, a song made by CHiAKi KURiYAMA.
An interesting "vaguely darkish" electro pop song by a female vocalist.
The lyrics is quite symbolic and can be interpreted in different for me. The visuals are good, maybe sometimes too simple. The music video itself is just as if not even more symbolic with few hints, therefore it was for quite hard to really understand what it was all about.
If I should interpreted it, I would describe it as being somewhat a cry "seize the moment" and let go of the past. The whole lyric is about the symbol of zero, resetting, be reborn, get
rid of your chains.
But again the music video itself is very vague in its symbolism, it is the lyrics which carries this song :)
