I did a little fist pump at the NIN mention and immediately deflated that the kid wasn't allowed to watch... Closer? I guess that one would come up on autoplay or as recommended. And I don't think any of the others could be that objectionable? Aside from the whole Broken film. But it's not like that one is fun to watch casually anyway.
And honestly? Given how Joe and Kanna worked things out, I cannot believe Mitsuki gave him that response. While "everything" may be a broad spectrum, there are still better ways to phrase it.
