I don't know when it happened, but at some point JJK became one of those manga where I just stopped caring about characters, because they kept getting unceremoniously killed off for shock value or to drive home how powerful someone is. But the shock value only works so many times before you start seeing everyone as expendable and stop getting invested. So honestly, even Gojo dying did nothing for me. I think the last character I cared about was Nobara, and I think it was her super pointless death that was the final, ironic nail in the coffin for my giving a shit.
