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.
Idiot Plot: The entire plot is basically one when Fridge Logic kicks in. The story would be probably over after about 8 chapters if Hiyama had basically tried or tested his master plan out first. And if Kuonji and the police weren't holding the Idiot Ball for so long, they probably could have stopped Hiyama before he ever even tried to implement his master plan.
Magnificent Bastard: Hiyama isnít afraid to get his hands dirty, and excels at turning the odds in his favor.
