Since Uruka has been mentioned here. I'm not surprised that with her incredibly strict upbringing, overbearing family, and lack of leisure time, she has been seeking outlets in lewd material. The more restrictive your existence is the more chances there are for you to become frustrated with your station in life. I imagine there are very few things in life that make Uruka feel truly liberated. Frankly, I think she deserves a lot more freedom, but to get that, she needs to take the initiative and usher in changes.
