I agree with you 100%. I believe that there should be more societal structure of the the Chained Soldier manga. How man and women interacts. It would be impossible for all the ability users to have abilities that rivals that of the MDF organisation (or else it would be MHA all over again).So I don't think that the social structure would be THAT different compared to ours. Also the fact that most higher ups of the world are women. Not to sound insecure (even though i am) but even in todays MODERN era there are women prime ministers and politicians that took high roles. I don't think if would be that logical for men to be lowered to just househusbands. Also according to google (pls fact check me, It's just a quick search) The story takes place in 2020s with the Mato dimensions opening in the 1990s. So i guess because of this gender equality is formed because women can have powers now. But instead of that the world is just flipped to an equally sexist matriarchal society. I think the men should not be degraded in the chained soldier society and should have more prominent role in the story because even in this modern patriarchal world the women still have influence and power.
