Dr. Shuichiro Kudo is walking home one night when he saves a small, winged child named Kohaku from a crow. In return for its rescue, the "child" reveals itself to be an angel, and offers to grant him one wish. However, what does a man who has everything wish for? Thus, Kohaku decides to stay with Shuichiro until he decides on a wish, as well as complete its original mission of find the missing Angel Master of Wind, Hisui.A four volume manga by CLAMP, it was animated in a short music video as well as recorded as a drama cd.If you were looking for the tropes involving wishes, see Make a Wish and Be Careful What You Wish For.
Calling The Angel Master Out: When Shuichiro and Kohaku finally find Hisui in the first volume, Shuichiro demands Hisui give Kohaku a proper explanation as to why she disappeared and why she refuses to return to heaven, saying that after all the trouble Kohaku went through, Hisui owes her student at least that much. Hisui complies.
Cats Are Mean: Played with in the case of Ruri and Hari; while they're Koryu's lackeys, they're technically Cat Girls and not all that mean.
Shinju is a much straighter example than Ruri or Hari. Every time he sees Shuichiro, he tries to bite him. Because he's in love with Kohaku as well, and considers Shuichiro his rival.
Celestial Deadline: Angels-in-training, like Kohaku, can assume an adult form during the day, but must be in a chibi form at night, while demons-in-training, like Koryu, can only assume their adult form during the night. If they fully master all magic, they can keep their adult forms all the time.
Crazy Jealous Guy: The Angel Master of Fire, Ryuuki, over Hisui. While he grows to accept that Hisui loves Kokuyo and wants to stay with him, he vows to hate Kokuyo forever.
And even then it's inconsistent at points - for instance, the Angel Master of Earth, Ransho, is given male pronouns, and the Angel Master of Fire actually bounces between the two genders on occasion. There's also Ruri and Hari, who are most definitely female demons.
Foreshadowing: Subtly done. Hotaru says that when she realized when her beloved Shusuke was going to die, she couldn't bring herself to smile and truly be happy even when she was by his side. God prevents Kokuyo from telling Kohaku about Shuichiro's approaching death because He doesn't want her to lose her happiness any sooner.
God Is Evil: Subverted: God's punishment on Kohaku for leaving heaven is seen as amazingly harsh by all of the characters, until it is later revealed that this is to ensure his meeting with Shuichiro's reincarnation 100 years afterward. So...God Is Good, only verymysterious.
God also seems to accept the relationship between an Angel Master and the son of the Devil, at least by the end of the quartet.
Hair of Gold, Heart of Gold: Kohaku is the purest of all angel, good and innocence incarnated and has shimmering golden hair. Hisui is a downplayed version, as he has dirt-blonde hair in a few illustrations, to show that while good, Hisui's more mature and worldwise than the naive Kohaku.
Loving Bully: Koryu to Kohaku. Ruri and Hari even point this out, much to Koryu's annoyance.
Meaningful Name: The name Kohaku gives to Sango the cat's Split Personality is Shinju, because he's beautiful and white like a pearl. Both names qualify for the Theme Naming listed below, as well, as Sango means "coral".
Na´ve Newcomer: It's heavily implied that Hisui had only recently become an Angel Master when she met Kokuyo, and she didn't immediately see anything wrong with having slept with him.
Our Angels Are Different: The four Angel Masters are all higher-power angels who report directly to God, and each one has control over one of the four elements of nature. Kohaku's role in heaven is basically that of a mother - nurturing the tree of life so that new angels may be born from it.
Our Demons Are Different: Demons get their energy by feeding on human souls, and because of this they can sense when a human is near death.
Even though Kokuyo is the son of Satan and the Prince of Hell, he's nowhere near as cruel and horrible as someone in that position might normally be depicted. His cousin Koryu is more like a typical Jerkass prankster who loves to target Kohaku, but as the story progresses his character develops to the point where he genuinely shows sympathy for her.
Poor Communication Kills: Played with. Though Kokuyo tries so hard to avert this by making repeat attempts to tell someone that Shuichiro is destined to die very soon, he's interrupted every time. God was directly intervening in his attempts to reveal this information, which could not be reversed or changed, so that Kohaku could maintain her happiness for as long as possible.
Pronoun Trouble: While CLAMP followed the general rule of 'angels are genderless', Tokyopop chose to give all angels female pronouns, leading to some Les Yay moments.
Purple Eyes: Hotaru has them, according to Koryu, and he thinks something's fishy with her because of it. And he turns out to be right - Hotaru's not human at all, but a wisteria fairy.
Putting a Hand Over His Mouth: Kokuyo does this to Koryu a few times. In the first volume, Ruri and Hari do it to each other in order to stay hidden while they spy on Shuichiro and Kohaku.
Ravens and Crows: Koryu seems to have some control over them. He's the one responsible for sending that crow after Kohaku at the start of the story.
Red String of Fate: This motif first showed when Hotaru rejects Shuichiro declaring she's not the person attached to the other side of his string. Later appears again when Shuichiro confesses his love for Kohaku, declaring her the person attached to his string.
Reincarnation Romance: God tries to avoid it by forbidding angels to fall for humans. When it happens anyway, he makes Kohaku sleep while bound to a tree so he can meet up with Shuichiro's reincarnation.
Red Herring: We find out lots of interesting things about Shuichiro's past; he has no parents, the woman who acted as his mother was a wisteria fairy and his grandfather eventually reveals he "just showed up one day, out of the blue" as a baby. Then there's the fact he looks a LOT like Kokuyo, the son of Satan, as everyone's quick to point out when the two first meet. So what's the big secret about Shuichiro, and why's it so important that God prevents Kokuyo from telling anyone? It turns out that...Shuichiro is a normal human and is destined to an early death. That's it.
She's a Man in Japan: In order to not put the series into a BL category, Tokyo Pop saw fit to change Kohaku's gender (Kohaku is technically genderless, but in human form is referred to as a boy).
In the sequel Legal Drug, Hisui is living life as a gay human man.
Supernaturally Delicious and Nutritious: Demons feed on human souls, but they consider the soul of a human with a pure and kind heart to be particularly tasty. This explains why Koryu, Ruri and Hari are so attached to Shuichiro - since he's unknowingly nearing death, they can feel his soul leaking from his body.
Theme Naming: Many of the characters in the story are named after gemstones: Kohaku = amber, Hisui = jade, and Koryu = garnet, just to name a few.
Time Travel: There's a spell that allows for travel back into the past, but it's a complicated ritual that requires teamwork. In the second volume Koryu offers to help Kohaku with it so she can find what happened to Shuichiro's mom...
Trademark Favorite Food: Milk and honey for Kohaku. Though it's not so much a favorite food as it is the only food he can consume, since all angels are forbidden to eat anything that once had life.
Tragic Keepsake: In the third volume Kohaku is forced to return to heaven, and Shuichiro is left behind with only one of the angel's earrings. He keeps it with him at all times after this, and is buried with it after he dies...allowing for his reincarnated self to possess it in the Distant Finale.
Truce Zone: The bridge between Heaven, Hell, and Earth.
Unishment: Hisui is stripped of her title as an Angel Master and banished to Earth. Since she and Kokuyo had eloped to Earth anyway, she's quite okay with this.
Strangely enough, Kohaku being stripped of all her powers turns out to be this as well - being powerless for the next hundred years means she will be able to spend that time sleeping, while waiting for Shuichiro's reincarnated soul to return.
What Is This Feeling?: Kohaku couldn't realize that she was feeling jealous for seeing Shuichiro's love for Hotaru since she never had felt jealous before.
Kouryu also had this reaction when he evaluated his unbridled glee at seeing Kohaku cry from his teasing.
Yamato Nadeshiko: Hisui. She wasn't voiced by Kikuko Inoue for nothing. After awakening, Kohaku tries to become one to help Hisui in homemaking.
