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.
Esoteric Happy Ending Ė The True endís attitude seems to imply that itís supposed to be considered at least bittersweet like True Ends usually are, but think about it. Mizuhara, Tojiko, Orihime and Toko are all dead and Reiji is alone. With closure, yes, but alone.
And Shinji got away.
Pinball Protagonist: Some of it is justified due to the Villains Act, Heroes React nature of the detective novel. Even so, considering how many choices and paths there are, it's still a little grating that no matter what you do, almost all major characters die anyway and despite all the posturing about stopping the villains to avoid more victims, Reiji generally fails to save anyone. On top of that, most of the villains work out their issues amongst each other (with fatal results) or achieve their goals before getting caught or disappearing, making you wonder just what use he is, other than being a narrator.
