* CompleteMonster:
** [[BigBad Apos]], with his golden hair, [[RedEyesTakeWarning crimson eyes,]] and beautiful features, resembles an angel. The truth is [[FaceOfAnAngelMindOfADemon markedly different]]. Apos is an immortal who [[{{Sadist}} finds amusement in suffering and agony]]. Apos hunts down female immortals and rapes and tortures them [[ColdBloodedTorture physically]] and [[MindRape mentally]] to consume their "core" of immortality; [[EvilTastesGood the suffering improves the taste]]. Apos obsesses over the heroine Rin Asogi and has his female subordinate Laura disguise herself as Rin to ruin Rin's name with a series of murders, and also satisfy his lust by raping her. At one point, he brutally crucifies and rapes Rin's best friend and lover Mimi simply because he was bored waiting for Rin's arrival. Apos is behind nearly every evil plot in the series and [[TheChessmaster engineers a plot to turn the world against immortals]] and turn on itself by causing a nuclear explosion with an immortal seen as a survivor. He then reveals the world tree Yggdrasil to the world to have humanity infected with the time fruits and become immortal so he can harvest them at leisure. Apos betrays Laura and forces Rin to kill her old lover, who Apos had turned into a carnivorous angel, in self defense, before personally executing her current lover--Apos's own father--and attempting to sacrifice Rin to Yggdrasil. When asked what he wants with the world, Apos's response is simple: "I want to taste it!"
** [[MadScientist Sayara Yamanobe]] is a repulsive, callous scientist, who masterminded the cloning program that killed the original Koki Maeno. She keeps the failed test subjects as ravenous, flesh-eating zombies that suffer every moment they're alive. When she has Rin in her care, Sayara proceeds to molest and then torture her to death while it's more than just implied that she molested and raped Koki as well, also being hinted this is "routine" for her. Sayara later just attempts to [[OmnicidalManiac wipe out all human life]].
* CrossesTheLineTwice:
** Episodes 1 and 2 seem to be made to test just ''how'' far you can push the network executives before they bring the censors crashing down on you. And quite frankly, it seems to have succeeded, as the violence and sexuality of Episodes 3 and 4 are practically ''benign'' in comparison to their portrayals in Episodes 1 & 2.
** Though almost as if flicking a giant middle finger at the networks for suppressing them for 2 Episodes, the Director crosses the line '''thrice''' with the nightmarish Episode 5.
* {{Narm}}: Apos. Sometimes he gets so...over the top (for lack of a better word) he comes off as less of an EvilGenius and more of just an annoying {{Bishonen}}.
* TearJerker: [[spoiler: Maeno Kouki's Wife's reaction to his death in episode 3, as well as Ihika's death in episode 6.]]
* TheWoobie: Yuki [[spoiler: who first loses her brother Shogo, then years later loses her husband Kouki, leaving her to raise their son Teruki alone. Add to that she never finds out what happened to them, is basically LockedOutOfTheLoop and seldom seen smiling.]]
