The Guardians are the student council of the school, whose task, aside from protecting and representing the general student population, is to preserve the Heart's Eggs of said children, and personages within general. They are also tasked with hunting for the Embryo (Due to Tadase's ideas towards creating himself as the world's king.), the legendary wish-granting Egg, which of course pits them against the Easter Company. It is primarily composed of four kids: the King's Chair, the Queen's Chair, the Jack's Chair, the Ace's Chair, and the occasional Joker's Chair, only taken via one with three or more Chara. Each of the members has a Guardian Character that represents an aspect of the person they want to be, which grants them special powers when they need it.The Guardians were founded by Tsukasa, making the current ones the second generation of Guardians.
- Absurdly Powerful Student Council: Not only are they leaders of the student body, they're also magical Guardians whose responsibility is protecting/purifying the Heart's Eggs of the students they watch over.
- Instant Fan Club: There are actually several of these, with overlapping memberships; they're formed prior to the start of the series. The Guardians as a whole (the boys individually, and even Amu and Rima before they join) each have fanclubs. Each fanclub is based on the target's outward character, not the inner one.
- Iconic Item: All the Guardians suddenly manifest an accessory related to their Chara when doing a Character Change, voluntarily or not, which serves as a visual indicator that hilarity is imminent.
- Magical Girl: Amu and the female members; the male ones are magical boys.
- Pink Girl, Blue Boy: Well, "Red Girl, Blue Boy". The boys were blue outfits, while the girls, including Amu, wear red.
- Playing Card Motifs: The positions are titled "King" (occupied by Tadase), "Queen" (occupied by Nadeshiko/Nagihiko, and later Rima and Rikka), "Jack" (occupied by Kukai and later Nagihiko), and "Ace" (occupied by Yaya). There is an occasional "Joker" position, which is currently occupied by Amu.
- School Idol: All of them, but especially Tadase.
- "We are all the main characters of our own stories!"
- All Girls Want Bad Boys: There's a reason why she couldn't stop thinking of the mischievous, catlike Ikuto. If that wasn't enough, one of her Guardian Charas, Miki, fangirls over both Yoru and Kiseki (the latter mainly because he has the same goal as many villains out there).
- All Your Powers Combined: Amulet Fortune appears to be this for Amu's four Charas.
- Bare Your Midriff: Her Amulet Heart transformation.
- Belligerent Sexual Tension: With Ikuto.
- Cool Big Sis: Ami certainly thinks so.
- Doting Parents: Her parents crank this Up to Eleven... concerning Ami, of course.
- Dude Magnet: many guys like her, and she even has an Unwanted Harem.
- Even the Girls Want Her: "Cool and spicy!"
- Hair Decorations: She has her X-shaped clips. When Character Changed with any of her Guardian Charas, her hairclips change shape to the matching card suit. One would assume this holds true for Dia as well, but Amu never does anything less than a full transformation with her on the rare instances when Dia is there to help, so we don't see her hairclip.
- Harmless Electrocution: She gets electrocuted on an electric line.
- Exposed to the Elements: Amulet Heart's costume is a skimpy cheerleader's outfit... definitely not suited for cold climates, as she found out when she used her Character Transformation on a ski slope.
- Frilly Upgrade: Amulet Diamond and Amulet Fortune.
- Full-Name Basis: Most every villain, as well as minor character Misaki, refers to her by her full name.
- Genki Girl: As Amulet Heart.
- Girlish Pigtails: Amulet Clover and Amulet Diamond.
- Heterosexual Life-Partners: Considers Nadeshiko to be her best friend. This turns into Platonic Life Parterns once it's revealed that Nadeshiko is actually Nagihiko.
- How Do I Shot Web?: Whenever she Character Transforms with El, she'd use powers, that she herself had no idea how they worked.
- I Just Want to Be Normal: Amu's hesitations about her duties as the Joker contribute to the whole mess in the Dia arc.
- Idol Singer: As Amulet Diamond.
- Image Song: Hanbun Ko No Heart. Since she is the main character, she gets a lot of them, but this is one of her few solo songs.
- Impossibly Cool Clothes: Amu's customized school 'look' and daily gear usually follow a cute punk chick aesthetic, which is unusual for a prepubescent Magical Girl. It does rightly earn her the nickname of "Cool and Spicy".
- Instant Fan Club: She had one prior to her joining the Guardians.
- Involuntary Dance: Ran did this to her via telekinesis in one scene in episode 6. She was not amused.
- Jerk with a Heart of Gold: She starts the series as one, with her inner self being very sweet and well-meaning but her outer self being very cold and stand-offish and doing things like calling Tadase a "shrimp."
- Magic Skirt: Season 1 gave her a perfect example - covering even though it appears to be at right angles to her body. Then season 2 goes the opposite direction and chucks a Panty Shot into the opening theme. Then again this may be the animators trying to point out that Amu is wearing some kind of cheerleader shorts under there.
- Mercury's Wings: Wings appear next to Amu's feet during character changes with Ran.
- Modesty Shorts: Wears a pair as Amulet Heart, but given how short they are, it's easy to mistake them for her underwear.
- Naïve Everygirl: Not usually an anime trope, but it fits here.
- Nice Hat: Amulet Spade gives her an artist's light blue beret.
- Nice Girl: Is this through and through despite her occasional Tsundere tendencies.
- Playing Card Motifs: Occupies the occasional Joker's Chair, where the requirements are three Guardian Chara or more. Her three main Chara are also named after suits of cards - Spade, Clover, and Heart.
- Precocious Crush: Given their age difference, her feelings for Ikuto can be interpreted as this.
- Power Gives You Wings: Subverted with Amulet Angel, Amu's transformation with El. She does have wings, but isn't all that powerful. Played straight Amulet Diamond, with her wing-like extensions
- Red Armband of Leadership: Amu has one of these (unlabeled), symbolic of her outward character's fame rather than any position. Perhaps this serves more of a purpose when she's recruited as the Guardians' Joker.
- Rock Me, Asmodeus!: As Amulet Devil, she uses an electric guitar to release powerful soundwaves that represses weaker abilities.
- Rookie Red Ranger: She's the most recent addition to the Guardians, but she has the most eggs and is the first to achieve a Character Transformation.
- Rose-Haired Sweetie: Perhaps moreso as Amulet Clover, but she's still a nice if easily flustered girl.
- Ship Tease: Ikuto particularly.
- Stocking Filler: As Amulet Spade.
- Stripperific: Amulet Devil
- Sugar and Ice Personality: Her public persona (and Impossibly Cool Clothes) gives her the "cool and spicy" title, but she just wants to be like any other girl and is actually somewhat shy. She opens up more as the series goes on, and the public reaction to this kicks off a story arc.
- Supernatural Gold Eyes: A yellow-eyed Magical Girl.
- Transformation Trinket: The Humpty Lock.
- Tsundere: Funnily enough, Amu is this way towards Tadase, often acting coldly towards him while inwardly squeeing over how cute he is. For example, when she sees him wearing a dashing white uniform:Tadase: This outfit is a bit big for me though. Does it look funny?Amu: *blush* Not really! And it's not like I think it's cuter because it's a bit big!!
- She tends to get like this around Ikuto at times too...but, Ikuto's...well...understandable.
- Unlimited Wardrobe: Not only does she have the most transformation costumes, Amu also has a big supply of fashionable outfits for her casual wear.
- Unwanted Harem: She even lampshades it at one point while contemplating her various crushes: "How many guys do I like?! Sheesh!"
- Wise Beyond Their Years: She seems to have a knack for philosophical speeches despite only being in elementary school
- Zettai Ryouiki: Amu's legwarmers tend to be just a little bit too low. JUST BARELY. Some of her other outfits invoke this though.

- We Used to Be Friends: With Ikuto. Thankfully, it gets better.
- Will They or Won't They?: With Amu in the anime, since it ends without animating the final chapters. Additionally, the anime's filler episodes had a tendency to add more Ship Tease between him and Amu.

- Cute and Psycho: Character Change with Temari. No one's entirely sure why you would want to be one of these, but you have to admit that it's better to be a psycho than to be a boy who's trapped in women's clothes because of some stupid traditions and has to keep up a "Yamato Nadeshiko" image EVERY DAY.

- "We won! But... is this really right?"
Voiced by: Shozo Iizuka, Eri Nakao (as Hikaru Ichinomiya) (anime)The true head of Easter Company.
- Creepy Child: Gives off this impression even when Amu anonymously encountered him in the street. He often says things like "Emotions are useless", for example.
- Cry Cute: Oh, Hikaru-kun!
- Greater-Scope Villain: His wish is the reason why his granddad is doing so many bad things to get the Embryo. And then it turns out that what everyone thought was the Embryo was Hikaru's Heart's Egg, which he threw away years ago. He DID need MacGuffin Delivery Service, just not for the reason he thought.
- Improbable Age: He's a kid who runs his own company.
- Evil Is Petty: Everyone wonders what Evil Plan Gozen wants to accomplish with the Embryo, but he just wants it as part of his rock collection. One more time: Hikaru ordered Kazuomi to send hundreds of innocent kids over the Despair Event Horizon because the Embryo was a shiny rock. The Embryo itself is so saddened by this that it stops shining and becomes a normal rock as soon as Hikaru touches it.
- Evil Sounds Deep: Except the deep voice is modulated by a device on his desk, which is part of the mysterious facade he puts up to the fact that he's definitely not old enough to be in charge of a Mega Corp.. In person, Hikaru sounds like the little kid he is.
- The Stoic: Taken straight to Emotionless Boy levels, since he discarded his Heart's Egg to cope with being groomed to run Easter and having no time to just be a kid.
- Not So Stoic: Once he regains his Heart's Egg and becomes the little boy that he truly is.
- Villains Out Shopping: The first time Amu meets Hikaru, he's out on the street in a shopping district for some unspecified, non-Easter-related reason. Amu shares a taiyaki snack with him. Although Amu gets the impression that he's a weird kid, neither Amu nor the audience are given any clue that he's in charge of the whole Easter corporation.
- Walking Spoiler: He's not seen until very late in the anime, and even then his true identity is only revealed in the last episode of Shugo Chara Doki!!. Just look at all these spoiler tags!
- Woobie, Destroyer of Worlds: He wants the Embryo for his rock collection, but he wants the rock collection itself to fill the void in his heart left behind when he discarded his Heart's Egg to withstand the stress of being groomed as the heir to Easter.
Tiny fairies who hatch from a person's Heart's Egg. They are chibified personifications of their chosen person's personality traits, wishes, and dreams, and they have magical powers of their own. Fusing with them induces a transformation into a Magical Girl (or Boy) and gives the chosen person special abilities.
- Anthropomorphic Personification: All Charas are living embodiments of their chosen person's traits, wishes, and dreams.
- Dark Is Evil: If a person's Heart's Egg is corrupted by negative emotions and thoughts, their Chara will turn into a dark-skinned, imp-like character with an X on their heads.
- Invisible to Adults: Only the owners of Charas and children can see the Charas. Everyone else can't.
