I don't understand why people are getting angry at others for finding the last couple chapters uncomfortable/ feeling bad for Lucy. Even for an adult work, this is some heavy stuff. I mean, c'mon, the plot is literally: "some dude's teenage wife gets raped by the president and impregnated by Jesus' corpse", of fucking course it's meant to be uncomfortable. No one's getting really "triggered" by it, because it's obviously not being presented as something good. They're mostly just shocked, not genuinely angry at Araki (and that's clearly the idea).
TL;DR: The chapter is conveying the emotions it's meant to. There's no reason to be angry at someone for feeling the way they're meant to feel about it. You're not supposed to brush it off like it's nothing.
