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.
Alternative Character Interpretation: Liana Chavinski only appeared in Chapter 4, but there are a lot of ways to look at her. Perhaps she was everything she said she was, and Eman asked for too much from her. Perhaps she lied about everything she said about herself, which is possible, because Eman has only her word and no way to prove that she was telling the truth. Perhaps she was a Manipulative Bitch who tricked Eman into helping her and getting his hopes up too high. Perhaps she was a demon masquerading as a human, as all part of a convoluted scheme to make Eman feel negative emotions and feed off of them. This character is just that ambiguous.
Mary Sue: The main character is so perfect and spotless, and of course everybody hates him for it, even his parents.
The soldier from the prologue is also a Mary Sue character who was so pure and perfect he even literally rescued kittens from trees. This is to contrast with the cruel and vulgar soldier who gun down an unarmed and subdued Iraqi for fun.
Narm: The heavy-handed writing and Off Model art produces this frequently.
Strawman: Any character who has a viewpoint other than the main character of the time. Even non-denomic bad characters are unnecessarily cruel and vulgar.
The Woobie: If Eman were a regular guy, he'd fit this trope.
