I ask my friend who buy it and it's true, Regular version doesn't have any pictures from Kara no Kyoukai~
Kalafina has just posting a new blog post from Hikaru, let's discuss this thing then XD
Check their new blog post here... then...
Hikaru said, 3 of us (Kalafina girls of course) has just trying new nail art, and the color and design is based on the personality of each members. So, let's guess it then, we don't have any clue except the pic.
I think the first one is Keiko nail, the second one is Wakana, and the third one is Hikaru.
Perhaps ? XD
