Oh come ON!
Her figure is weak.
She has a bit on the thighs, and the "gap" on the chest is the place where breasts aren't because she barely has any. There is no "ample bosom" there. Not an absolute washboard like Mami, but barely above the mosquito-bite level.
If you liked that sort of thing, fine. Some guys like stick-insects... but don't pretend she is curvy when she is blatantly and overtly NOT.
The mangaka sorely needs a reality check.
This is like those JK manga where a girl cries over "putting on weight" because she is imperceptibly less anorexic than her friends. As if not looking like you're starving to death somehow equates to morbid obesity.
