I actually thought it was easy to understand. This is another "Girls Power" PV.
- Ayu walking in shiny pink and blue with the stuffed toys represents how girls loves to catch people's attention with their looks. She's curious and she has control over the situation (she's got a key in her hand she proudly exposes).
-The commander thing has nothing to do with Hitler, it's just showing how a woman can can be strong enough to command a "troop of guys" (not referring to army but their power in society, how they can actually have jobs such as being presidents and stuff).
-The maid is NOT whipping a GIRL but a GUY. Again it's nothing more than girls power. While the maid is in a lower social position than her boss, she's still able to get him under her skin.
-The black lady with cat face is turning that guys life into a hell because girls can do that.
-The girl in white with the butterflies shows women can live fine without a man by their side.
-Ayu's afraid of facing her true self (the 2 ayu's) specially because she doesn't want to lose her identity (faceless ayu) but she gets crushed by her own insecurities (the elevator). [This part shows that even though women can be determined as showed before, inside they still have a lot of insecurities to deal with]
-However, in the end, because of the insecurities, as much as women want to show how strong they have become, the men still have the ladies under their skin
Women can't just live without men.
