Oh boy. The opening to this was hard to watch. Like, I've pulled up another tab so I don't have to watch cause I'm so worried about the Xenos and I don't want them dead or hurt. Oh no, oh no, oh no. I hear Wiene crying out. Please help her someone.
Haven't mentioned it before but Evilus is a bit too on the nose for me personally.
Creepy guy at the beginning, what your deal? And what is this of kids long ago Ikelos? I am officially curious. OOOOOHHHHH! Ok, so, mid-episode. If I remember my mythology correctly, Daedelus was the greek architect who made the labyrinth. So appreciation for that nod to mythology. Also, appreciation for the subtle d on the eye key, however, gross that is. But the fact that the group did all the kidnapping for money to find a thousand-year-old project and then proceeded to sell the Xenos because once again humanity sucks, is just wrong on so many levels.
Now, onto the red eyes at the end. My thoughts are that when a Xenos gets angry enough, they have the ability to go full monster mode. Or, alternatively, if the show's explanation is correct, maybe all monsters have the capability of having a conscious but after years of fighting for their lives, they lost their sanity.
Backstory idea:
The humans and monsters once lived in perfect harmony, then tragedy struck and the races split. After decades of war, the monsters were sealed inside the dungeon to slowly lose their sanity over the centuries while the humans prospered, slowly forgetting about their foes locked underground. When the Gods came down years later, the humans rediscovered the monsters who's minds were now lost and were forced to kill them as they attacked anything in sight. Now, after being exposed to the voices of humanity, they slowly regain their memories and ability to have a conscious.
Ok, this one was way too long. Hope you enjoyed what turned into a mini fanfic at the end. :
