I have to agree here. This is not a lighthearted manga. If the thought of "girls = objects = owned", shitty rapist men, female abuse, incredible levels of gender discrimination, any level of NTR (guys can steal "ownership" of girls by beating other guys), an incredibly naive and over idealistic MC that (almost intentionally) remains ignorant in the face of serious shit and terrible tragedy, or anything attached to any of those, LEAVE HERE AND DON'T COME BACK.
But if you make it past the first 7 or so chapters, the story lightens up. Barely. Not really. I have no idea if I want to keep going or not. You've been warned twice.
