Hahaha. I love this~

So unfair that Midnight Blade is the 2nd tallest (if I'm correct) despite being the youngest.

Well, it has to be one of the girls... maybe Breeze Dancer? Cause Azure is much more playful, as you can see with the dialogue in the game (expressions tho.)

I also have a headcanon that Scarlet is the perverted, and mischievous of all of them. C;

O.o Oh wow, I didn't expect Azure to be Midnight's sister, seeing that her facial expressions are more playful and nice (from the dialogue), rather than stoic... :L
