skinny-fit Japanese girl who trains a lot in boxing and goes for a low bodyfat percentage, so she's lean muscular in place and really thin in others. super lean lower spine if you like the extreme type where you can see every bump even when she's not bending over.
starting off with a pic where she covers her lower back and shows off her shoulder blades:
