This is probably really stupid on my part but I thought of it as a reference to Dragonball when I first saw the title, I mean there are 7 Dragonball right? Though its odd to call the 7 Dragonball pieces so its probably not actually referencing to that, still it was the first thing that popped into my head, which is probably due to the fact that I'm a big fan of the anime, I used to watch it all the time when I was younger.

I can't remember where but I'm sure there a thread on here about it. But on the track list it comes after Love 'n' Hate which if you listen to it it counts up to 7 and then goes to 0, which someone speculated that it refer to her relationship with Tomoya Nagase whom she was in a relationship with for 7 years and it ended with nothing. So the Pieces of Seven would be the pieces of the seven years they were together? Which links well to Day if what people speculate about the song and PV being about her past relationship is true.
