Makoto and Rose are conservatively dressed, but people will try to argue that Rose has large breasts...and apparently, having large breasts is a no-no...even IRL.
And, during Makoto's dizzy animation in 3S, you can temporarily see her bra under her gi. So, you could argue that that is male gaze.
Karin is protected by two different layers of clothing under her skirt, one of which extending to the level of shorts, so you'd think she'd qualify. But, some people might argue that a skirt in and of itself is designed for "male gaze".
Ingrid is actually showing very little skin. But, she's just "weaboo loli fanservice". So...shrug.
I dunno...the term "Male gaze" can be interpreted to mean anything and everything even remotely attractive.
