There’s no actual triggering events, but Midori is Midori so he will repeat his catchphrase of wanting to unalive himself and there is a short comedic moment regarding this that could be uncomfortable?

And there’s the running ‘gag’ of Midori commenting on Chiaki’s physical affection as ‘sexual harassment’. Basic era Enstars stories are really of their time sometimes.

Those are the only things I can think of that might be uncomfortable.
