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: Due to the grim setting and backstory of the game. Is Akira a brooding anti-hero or dark and apathetic due to his upbringing as a child soldier? Is Keisuke a spineless wimp or does he have reason to act like he does? Is Arbirtro simply doing what he can to survive in a Crapsack World?
Shiki. He may not be an outright villain, but even in his best paths, he's still a raping murder machine. That doesn't stop the fangirls from creaming over him. He does literally have leather pants, though. With zippers.
Admit it, you thought that when Keisuke accidentally got Akira's blood on him, you thought he died.
Keisuke's death. If that wasn't anymore heartbreaking, Akira finally sheds tears for him.
In the game, the majority of the routes typically has at least one of Akira's potential love interests die. Keisuke dies in every route but his, Rin and Nano dies in Shiki's route,Shiki dies in Rin's and Nano's route, etc.
The Woobie: Everyone in the cast-with the exceptions of Emma , Gwen, the Vischio, and Shiki-counts somewhat as this.
