History YMMV / SekaiOni

** Azuma's mother is a smaller case, given we barely see her. As far as the audience knows, she left Azuma in the hands of her brother's family, and is presumably unaware of how [[AbusiveParents utterly fucked up their abuse is towards her]]. But then when she's finally shown, she either isn't aware of or doesn't seem to care about the fact that [[spoiler:said brother and his entire family are ''dead''.]] Even worse, in the final chapter, [[spoiler:she abandoned Azuma '''again''', without any clarification for why she did it either time; was she [[MarriedToTheJob wrapped up in work]] and unable to see her, or was she as [[LackOfEmpathy self-centered and uncaring]] as Azuma was and ran off without realizing why this was a bad thing?]]

* AlternateCharacterInterpretation: Just how much of a hero is Azuma by the end, or rather how much did she grow as a person? The question is a driving force throughout the entire story, and while we're shown her LackOfEmpathy and her broken, childish understanding of the world around her, the story only ever affirms one thing: [[spoiler: she doesn't even hesitate nor ''comprehend'' why killing off all of Maze to save her world is a bad thing despite everything she's been through.]]

* NightmareFuel: Holy mother of god, it's like if ''VideoGame/SilentHill'' was blended with a battle shonen. From the sheer FanDisservice of Kuroe and the (thankfully off-screened) sexual assault that Azuma's uncle commits to her, to the psychological reflections in mirrored surfaces and the sheer HeroicBSOD to spare for the entire cast, to the World Devils and the brutality a number of characters face in their ongoing battles. There's a reason why the manga is tagged as having psychological horror.

* CompleteMonster: [[BigBad The King of Maze]] is the sadistic mind behind the devils. Initially a baby forced to feel the darkness of the inhabitants of his kingdom, the King embraced the darkness, gaining enjoyment through the suffering of others and even his own, going so far to kill people from a prosperous district after discovering that they were happier than the rest. Continuing with the exploitation of the "Devils", actually ChildSoldiers born to serve, and realizing that the worlds of Maze and Zera were going to crash, the King of Maze ordered the destruction of Zera, sending the devils to destroy it, causing multiple disasters, with the city of Buenos Aires being totally destroyed. Capturing the real bodies of the Cheshire Devils, the King promised to reunite one of them with her mother if she killed her "brothers", and after she did this, the King brought her to watch her mother's dismembered body. In the Last Night, the King created a [[HumanShield shield]] using the lives of his people as fuel before becoming the [[EldritchAbomination World Devil]], admitting that [[NotSoWellIntentionedExtremist despite his initial claims]], he really didn't care about the worlds, before trying to destroy the Earth in the name of darkness itself and [[ForTheEvulz his own entertainment]].
