girls have mechanoids, 5 meter robot costumes for fighting monsters and evil.

but! There is one catch, in this world, all household chores are now handled by men!

That is, in short: now men are required to wash floors, dishes, vacuum, take care of children, wash dishes, tidy the house, work, do homework. And the women go to training in their mechanoids, save the city and do nothing.

A small clarification: not all women have mechanoids, only those women who are 18 years old have permission and agree to use mechanoids to fight monsters and evil.
