These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The Ash (Ryugyu Shelter) arc is full of these as well- Miho's death, Mark's realization that exposing the shelter's Dark Secret will only make things worse and that all he can do is keep on doing his job as an entertainer as people die around him, Player Hino and Mr. Director with the dying patients, the deaths of every named character in the end.... Also considered as such in-universe, as several characters are shown crying as they finish reading the Apocalyptic Log.
