* FoeYay[=/=]HoYay: Many people interpret the Bokor's obsession with Maeda this way, [[spoiler: which is only exacerbated by a cryptic dream sequence he has about it which implies that they knew each other when it was human, and the fact that it knows his name]], even though in-universe it's explained that Maeda is simply the first person it's encountered who also meets the conditions--whatever they may be--to also become one, and it's just spreading the infection. Also lampshaded by Yoshioka:
-->'''Yoshioka:''' In other words, "Maeda-kyun is the only one for me <3" in a way.
* FridgeBrilliance: Why is no one aware of how the Bokor [[spoiler: knows Maeda's name?]] Every time it revealed this fact, it had just used its sound blast attack, so whenever it said anything, everyone probably only heard ringing.
* TheyPlottedAPerfectlyGoodWaste: [[spoiler: Many people thought Shinpei was doomed as soon as it turned out that he refused to kill his zombified son, and instead chose to keep him restrained.]] However, a good amount of character development and a clear loyalty to his friends has kept him alive.
