As soon as 16-year old country girl Emma arrives at the city of Hawk Eye, every man in the city falls madly in love with her. The king in particular tries to force her into marriage... and ''then'' a sorceror kidnaps her.

The sorcerer introduces himself as Shion, one of the youngest and most talented in the nation. He explains to Emma that she is cursed with the Echidna, a mysterious magic that happens every 500 years where a girl is born with her heart packed with such powerful dark magic that it has the potential to destroy the world. With the Echidna, one could rule the world, and Shion explains that people are going to try and hunt her down to get her heart.

However, just when Emma has given up on living a normal life, she is told that there exists a ritual that might rid her of the Echidna curse: [[TitleDrop Magico]], which consists of many difficult trials... the first of which requires Emma and Shion to marry each other.

Do note that [[http://www.shonenjump.com/e/rensai/magico/index.html the official spelling]] of this manga's name is with a lower-case M as "{{magico}}". That is not a typo.

!!Tropes include:

* AbusiveParents: [[spoiler: Shion. His mother couldn't accept her son wasn't "perfect" and forced him to go through a forbidden ritual designed to improve his abilities at the cost of the lives of ten children. And when that ritual failed and ended up doing the exact opposite, his mother [[ParentalAbandonment abandoned]] him. She apparently made Faust go through it, and it turned him into a monster.]]
* TheAce: Raven, headmaster of a magical school, brilliant scholar, powerful mage, kind hearted, and in love with Emma just from reading about her and what she had to endure.
* AMagicContractComesWithAKiss: One of the rituals for Magico requires that the married couple kiss each other.

** The eldest of the Magi, Gaspar, takes the cake though. He [[spoiler: kills both of his brothers]] to "nourish" himself, and it's revealed that the reason they wanted to slaughter everyone was [[spoiler: so Gaspar could, in his own words, "to cheer myself up".]]
* {{Badass}}: Gaspar, the oldest of the Magi. Yes he's an AxeCrazy {{Jerkass}}, but what else do you call a guy that's [[GoodScarsEvilScars covered in scars]] and [[spoiler: can sprout blades from those very scars, even newly formed ones.]]
* BadassAdorable: Luu.
* BerserkButton: Don't harm Emma in front of Shion. Also, don't degrade Luu's family. Neither will repay you kindly.

* BigEater: Luu, as well as a SweetTooth.
* BigBrotherAttraction[=/=][[BigBrotherWorship Worship]] / [[BigBrotherMentor Mentor]]: This is either Faust's previous relationship with Shion or just his own perverted memories of those times.
* BigBrotherBully: This is his current relationship with Shion.
* BigGood: [[spoiler:Sephirot. To articulate, they kidnapped a baby Emma after Oz infused her with Enchidna and put her into the house as a 15 year long ritual so that one day when she works on completing Magico with someone she would have a power to help make a better tomorrow and fight against Oz.]]
* BigNo: Emmas reaction to [[spoiler: another girl kissing Shion]].
* BigScrewedUpFamily: The people Shion comes from.

* BornLucky: Emma has fantastic luck when gambling. Even when the people are cheating via magic, she WILL NOT lose.
* CaptainErsatz: Luu bears an ''incredibly'' strong resemblance to [[TegamiBachi Niche]]. Strikingly similar appearance, seen as cursed from birth, thrown off a cliff by superstitious villagers, grew up in the wild, obsessed with meat, ridiculously strong for her size, lack of human interaction... if not for her borderline GenkiGirl personality, she'd be a complete clone.
* CasanovaWannabe: Faust tries to approach girls with lines asking to touch their boobies, not realizing this is why every girl generally hits him.
* CombinedEnergyAttack: [[spoiler: While fighting against Oz, Shion and Emma refuse to give up and as their fight can be glimpsed at from the Earth, many of their friends and allies pray and wish for a "dream" or "tommorrow" which empowers the pair and allows them to defeat Oz, who wishes to destroy the whole world so he will be alone with the woman he loved.]]

* CordonBleughChef: Emma, Shion's the only one who can stand her cooking, ''herself included''.
* DarkActionGirl: Ain.
* DeclarationOfProtection:

** Rogue is also this towards Lily, such that when Lily was kidnapped he didn't even stop to sleep while looking for her.
** Luu has the same feeling towards her new family, willing to risk her life to protect them.
* {{Determinator}}: Shion gets to show it off the most, but a lot of the named characters in the cast qualify.
* DualAgeModes: CINDERELLA FEVER!
* EldritchAbomination: [[http://img.batoto.com/comics/2011/11/02/m/read4eb1c42ca3254/Magico_33_MRI_Magico_33_04_MRI.png The true form of Echidna when ]][[http://img.batoto.com/comics/2011/11/02/m/read4eb1c42ca3254/Magico_33_MRI_Magico_33_05_MRI.png released from the woman host.]]
** [[spoiler:[[http://www.mangahere.com/manga/magico_iwamoto_naoki/c061/19.html Here's Echidna's head.]] Yes, that is the moon.]]
* EquivalentExchange: Magic can only be used by people who've accomplished the accompanying Rituals, which could include kissing a person, reciting specific verses, hunting down monsters and procuring certain artifacts. And even after all that, magic still can't be used indefinitely - it will eventually "run out" and the Ritual for that magic will need to be accomplished again. [[spoiler: And unusually, it seems that it's possible to set the conditions of the exchange, such that one can create a unique type of magic as long as he or she can invent the proper Ritual, wich is what Faust is trying to do with Ain's help.]]
* EvenEvilHasLovedOnes: [[spoiler:Oz, who wants to destroy the whole world, wants this so he can be alone with his wife and no longer have to worry about people coming after them.]]

* TheGadfly: For Joshua, mocking people seems to be his standard form of social interaction.
* GoldenSnitch: The quiz show pulls this out for the final question. Played with in that [[spoiler:Emma gets it wrong, but the judge lies and claims it was right.]]
* GodzillaThreshold:
** Luu using [[spoiler:Cinderella Fever]]
** Shion using [[spoiler:his strongest magic which comes at the cost of something deeply treasured. In this case, [[LaserGuidedAmnesia his happy memories of his times with Emma and their family together]].]]

** Grandpa Garlan is one of the rare bug-men, specifically being half-giant-centipede. He's also the guy who generates the bug monsters for Shion's Broom Magic Ritual.
** [[spoiler:Shion's family tries a ritual to turn Shion into a half demon but it fails and he became a "Degraded Human".]]
* HandicappedBadass:
** [[spoiler: In chapter 18, Luu's sight, hearing, smell, and sense of pain are sealed by [[AxCrazy an evil Magi]]. She still wins by relying on her survival instinct and [[CrowningMomentofAwesome leads to great upset.]]]]
** [[spoiler:Shion too. The failed ritual he endured as a child turned him into a "degraded" human, leaving him with reduced intelligence and a far weaker body. He still managed to become an Archmage through ''sheer willpower''.]]

* InstantAwesomeJustAddDragons: Shion ''lives'' in one.

* {{Jerkass}}: Joshua.
** JerkWithAHeartOfGold: [[spoiler: He does care about some people, but won't ever show it. His attacking Faust when Faust tried getting Shion to sacrifice himself for an evil ritual shows that much.]]
* KillItWithFire: Shion's magic broom is weak to fire magic. He knows this, so he has developed plenty of counters if someone tries to exploit it.
* LaserGuidedAmnesia
** [[spoiler: Sephirot has a vampire that can eat memories and used him to cover-up Emma's confession she's Echidna.]]
** [[spoiler: Shion's strongest magic requires he sacrifice something incredibly precious to use it. For him his happy memories are taken.]]
