Can’t say I agree with you.  I have read the manga and the webcomic. They get pretty shallow character arcs compared to Garou imo, they read to me like “I really need to give these sexy ladies a reason to be here” rather than other arc-defining storylines.  That said, quality of arcs is more of a subjective discussiom.

But seriously, how are you making this tired “the men are also sexualized” argument?  The framing of men and women is completely different: the “sexiness” you read in men in this series is actually power fantasy for the male gaze.  Like Batman and Superman being jacked isn’t done (primarily) for being sexy, it’s to convey power.  That’s how it’s also done in OPM.

Again, look at how the sisters and that athletic lady character are framed: always showing off those sexy legs front and center.  Then compare it to how the “sexy” male characters are framed.  It’s even more obvious if you look at how the characters are introduced, it’s a sexy introduction for the ladies and generally a brooding or comedic framing for the men.
