@MFauli, the Testament gif is definitely the most pervy, but in comparison to the rest of the series...is quite tame.

Shinta is right (and her character design is indeed apparently in support of this particular niche fetish, why else would she raise her arms like that constantly?), despite me not really being concerned about that particular detail. Her hair and Ayame's still looked great this episode. SidePonytail-chan's too.

It was the storytelling (and apparently the armpit detail) that was lacking.
