''Angel Sanctuary'' is a 20 volume epic manga by KaoriYuki, which spawned a series of Drama {{CD}}s and a 3 episode {{OVA}}.

[[FallenAngel Angel]] Alexiel rebelled against God. As punishment, her body and [[OurSoulsAreDifferent soul]] were separated, and her soul was [[{{Curse}} cursed]] to [[{{Reincarnation}} rebirth]] into an endless loop of human incarnations. This is the story of her latest incarnation...

1999 in Tokyo. Setsuna Mudo, a [[TroubledButCute high school boy,]] finds his life interrupted by [[OurAngelsAreDifferent angels]] and [[OurDemonsAreDifferent demons]]. Both Heaven and Hell seek Alexiel's soul, housed within him, but Setsuna has his own life, with his own problems. Not the least of which is the internal conflict of being in love with his [[BrotherSisterIncest biological sister]], Sara.

In the struggle to awaken Alexiel's soul, Setsuna's life is threatened and Sara [[HeroicSacrifice dies]] protecting him. The bulk of this story follows Setsuna's journey to [[OrpheanRescue find and rescue]] his sister's soul; travelling through the [[TheUnderworld afterlife]], through {{Hell}} and {{Heaven}}, with the help and hindrance of [[LightIsNotGood angels]], [[DarkIsNotEvil demons]] and other mythical beings. Through this journey, Setsuna learns important lessons that help him become the hero and saviour that Alexiel wished she could have been.

This series delves into issues such as morality, destiny and social conformity, told through beautiful art and themes inspired by multiple religions and mythologies.

!!Tropes used in ''Angel Sanctuary'':

* AIIsACrapshoot: ''Angel Sanctuary -Digital Angels-'' is a computer game gaining popularity at both Setsuna's and Sara's schools. There have been reports of mysterious deaths and strange behaviour, possibly related to the game, but it's not until Sara's friend Ruri gets a copy that they find out the truth: What at first appears to be an interactive A.I. turns out to be [[spoiler:a way to communicate with the Inorganic Angel, and a key component in Katan's plan to break the curse that's holding Rosiel prisoner.]]
* ApocalypseMaiden: Many high ranking angels have the [[PersonOfMassDestruction power]] or [[WeaponOfMassDestruction technology]] to destroy the world. [[spoiler: This is part of God's experiment - He's waiting to see who will actually do it.]]
* AxCrazy: Being murderous and unstable is culturally acceptable in Hell.
* BigBad: Rosiel - He wants his sister back. His theory is that if he can make Setsuna's life miserable enough, Alexiel will stop wanting to be this human boy and wake up as her original self.
* BigBadWannabe:
** Sevothtarte - He's a cruel dictator feared by all of Heaven. He's pulling the strings behind puppet king Metatron's back, but the high-ranking angels don't respect him (they don't even bother gracing council meetings with their presence), while rebels are plotting his downfall. Since she openly opposed his policies, he disposed of Jibril [[spoiler:by causing her incarnation as Sara]]. Ultimately, Sevothtarte [[spoiler:is revealed to be Lailah (an angel scientist branded as fallen after she had been gang-raped) and becomes a pawn to Sandalphon and Rosiel]].
** Sandalphon - He does pose a serious threat to almost everyone. [[spoiler:He has the ability to manipulate his twin brother, Metatron, but he is essentially a child, and he overestimates himself. Because God has nicknamed him "Little YHWH" (basically ''God Junior'') Sandalphon believes himself to be superior to the angels from previous sets of twins, particularly Rosiel. Although Rosiel is not as powerful as Sandalphon, he outsmarts Sandalphon, then absorbs and assimilates him.]]
* BigGood: Alexiel - She once promised Rosiel she would kill him before his insanity made him dangerous, but when the time came to do it, she couldn't. She tries to keep Setsuna safe, in the hopes that he will fulfil the promise for her[[spoiler:, but only Alexiel is a match for Rosiel.]]
* BlackAndGreyMorality: As products of a Creator [[spoiler:with no morals]], all anyone does is try to make the best of the hand they're dealt. From angels trying or failing to live up to their holy image, to demons fulfilling or rejecting adversarial roles, and with humankind in the middle, the importance, the quality and even the definitions of morality vary greatly.
* BlindIdiotTranslation: For the most part, this series has very reliable translations, however there are a few weird moments:
** Moonlil is called [[JapaneseRanguage "Riru"]], instead of Lil, for a chapter or so (VIZ).
** Sandalphon's hair colour is originally described as "like peacock feathers". In English (VIZ), this is translated as "rainbow coloured".
** At one point, the German translation refers to Setsuna and Sara as twins instead of siblings (their ages are stated as 16 & 15, respectively.)
* BrotherSisterIncest:
** Setsuna worries that this relationship will make Sara's life difficult, but their feelings are mutual. Even though both of them are consistently faced with opposition (whether from human society or from Heaven),[[spoiler: their love never falters.]] They do, through the course of their separate adventures, mature and become aware of the sacrifices their allies are making to help them, and the impact their actions have on the people around them. In the end,[[spoiler: they are reunited in Assiah (Earth.) When Kurai points out that they will go back to their human lives and still be siblings, Setsuna is convinced they'll find a way to make it work.]]
** In Heaven, all close relationships are taboo, and all angels are related. But, with the exception of twins, they don't tend to think of each other as siblings. Though the dynamic is different, it still applies because if any of them have children together, genetic mutations are a valid concern.
* CouncilOfAngels: The Angelic Hierarchy is God's military, run by a specially created Monarchy. Their job is to keep peace on Earth, but since the latest divinely ordained Ruler is a perpetual toddler, power falls into the hands of his Prime Minister -a tyrannical dictator. Without a competent leader, the angels succumb to class division, and many turn to crime. This also inspires an organised rebellion. Truly holy angels are the noteworthy exception.
* CrapsackWorld: Earth? [[YouCantFightFate Doomed]]. Hell? [[DeathWorld Dangerous for most]]. But hey, it could be [[FromBadToWorse worse]]. You could go to [[{{Dystopia}} Heaven]]...
* CruelAndUnusualDeath: Wing clipping punishment for angels. Not only are angel wings very sensitive, they function like an angel's immune system. First the wings are removed, then virus and infection set in, leaving the victim to live out their final days in a starving, rotting, zombie-like state.
* {{Curse}}:
** Earth Command Curse - During the Second Great War between Heaven and Hell, Alexiel uses this curse to imprison Rosiel within the Earth. This essentially [[LogicalWeakness earths]] the 'electric angel', as an alternative to killing him. - This curse is broken by [[spoiler:Katan, one of Rosiel's loyal followers, using forbidden black magic.]]
** Language Power Spell - During the same battle where Alexiel cast her curse on Rosiel, he seriously wounds her, facilitating her capture. This is the curse the Angel of Judgement, Uriel, sentences Alexiel to, during the trial in which she is branded Fallen. Her body and soul are separated; her body imprisoned in Angel Crystal, her soul sentenced to cycles of reincarnation in human lives. Always short, difficult lives, ending in brutal deaths. - This curse is broken by [[spoiler:the Spirit from Alexiel's sword, saving her from suffering by performing a mercy killing in the life she had before she was incarnated as Setsuna.]]
* DarkIsNotEvil: Oppositions like "angel/demon" and "Heaven/Hell" do not indicate moral alignment. There are selfish ''and'' selfless angels, just as there are fallen angels who fight injustice ''or'' who live only for hedonism. In fact, a race of bat-winged, dark-skinned demons (not fallen angels themselves, but descended from them) are called "Evils" - they worship nature spirits and keep to themselves, but their existence is threatened by the violent conflicts between Heaven and Hell more than once.
* DysfunctionJunction: Flaws, weaknesses and imperfections play a large part in what makes all of these characters so interesting and compelling.
* EarnYourHappyEnding: More bittersweet for some than for others. Setsuna works hard to keep his friends safe, and he always says he'll make it so everyone will be happy. [[spoiler:It is his influence that convinces some beings from warring races to work together to free the universe from God. After all this, he finally gets to go home, with Sara by his side.]]
* ElementalPowers:
** The interplay between elements is so delicate that the [[FourElementEnsemble four angels]] who serve as their guardians must remain alive at all costs. [[spoiler:However, preserving their brains would be enough, judging from Sevothtarte's plans for Jibril's future...]]
** Angels use [[OurSpiritsAreDifferent the Grigori]] to maintain elemental balance around them while they use magic.
** The [[ElementNumberFive fifth element]], which is controlled by Adam Kadamon, is the fabric of creation. Being split-cloned from Adam Kadamon, Alexiel and Rosiel can also control the fifth element. [[spoiler:So Alexiel's power over nature and Rosiel's electromagnetism could create any world they wanted if they worked together.]]
** [[spoiler:Setsuna defeats God because the source of His creative power (access to the elements through Adam Kadamon) is sealed away by Michael, Uriel and two of the elemental dragons summoned by Kurai.]]
* EvilVersusEvil: Although [[BlackAndGreyMorality "evil" is relative]], Setsuna faces hostility from various factions that ''also'' oppose each other - even within Heaven and Hell, respectively. In Heaven, [[BigBad Rosiel]] is plotting to reclaim his throne from [[PuppetKing Metatron]] and [[BigBadWannabe Sevothtarte]] [[spoiler:(Sandalphon eventually joins this conflict)]], while in Hell, [[SevenDeadlySins the Satans]] struggle to cooperate with each other.
* GoodWingsEvilWings: Subverted. Most angels, including most fallen angels, have large white bird wings. The Evils have bat wings, intimating their race, but not their moral alignment. Lucifer's and some of the Satans' wings are deliberately tainted black to symbolise their rebellion, but Elemental Angel Uriel's black wings are naturally occurring. Af has bone wings, and he is an innocent i-child (illegitimate angel). There is also symbolic art of Sandalphon with peacock-feather wings, of Belial with butterfly wings, and of Setsuna with one bird-one bat wings or with bone wings.
* GreaterScopeVillain: YHWH (God) - Alexiel's rebellion was justified. [[spoiler: The universe was God's experiment, which he deemed a massive failure. To save everyone, God must be 'killed'.]]
* LightIsNotGood: See: DarkIsNotEvil.
* LoadsAndLoadsOfCharacters: If you use all your fingers and toes you may count the REALLY important ones.
* NotBloodSiblings: Subverted. Setsuna checks the Family Register to make sure, but he and Sara look related because they ''are'' related. He's disappointed, but not surprised.
* NoWomansLand: Justified - Through God's laws. Heaven's society does not go easy on anyone, but misogyny makes career advancement much harder for female angels. The few women in high-ranking positions are met with envy and suspicion. Victims of sexual crimes are blamed for being "temptations" and ''branded as Fallen''. With Sevothtarte in charge, the situation becomes worse, as he has no sympathy for women at all.
* ShoutOut:
** Setsuna speaks of the ''Film/LadyHawke'' movie, unknowingly speaking about [[spoiler:Alexiel and Lucifer]].
** When Rosiel gives Kato "drugs" in capsule-form, Kato says it reminds him of the movie ''{{Akira}}''.
** Lucifer gets called out for his ''[[EdwardScissorhands Scissorhands]]'' outfit.
* TitleDrop: The first time is early on with the ''Angel Sanctuary'' videogame that is used to release Rosiel from his earthly prison. Much later in the series, when looking at Eden, it's also called Angel Sanctuary as an actual sanctuary for angels.
* WingedHumanoid: Most angels and many demons are humanoid with wings. Their wings are not always visible, but usually emerge for flight or with the use of certain powers. In addition to channelling astral powers, wings also function like an immune system. The vast majority have two wings. One-winged angels are a shunned minority. God's most perfect creation is a six-winged hermaphrodite, and His attempts to recreate this being have resulted in supremely powerful sets of twins, with a division of six wings between them. For example, Michael has two wings, while his twin, Lucifer, has four; Alexiel and Rosiel have the equal divide of three each.
