Cielo is a 20 years old circus performer and professional acrobat who saves Aleli from being caught by a man she stole from and takes her to the Inchausti mansion, where eventually she gets a job as maid. There, she starts falling in love with Nicolas, as well as developing a great affection for the orphanage kids, who mostly view her as as a sisterly figure. It is later discovered that her real name is Angeles Inchausti, true heir of the mansion, who was abandoned by Bartolome and Justina at an early age in order to get the mansion to themselves.
Nice Job Breaking It, Hero: Early in season one, she grabs Bauer's most recently found lead to Eudamon to examine it... and when she gets angry at him, she throws it away. And since it was just an egg... well, it breaks.
Subverted, since when the egg breaks, Bauer is able to discover the real lead, which was inside the egg.
Ninja Maid: A maid who knows acrobacy, dancing, jujitsu (among other martial arts), and time travel people!
Parental Abandonment: Turns out it's because both of her biological parents are dead, although her adoptive parents are quite nice people who make up for it.
Who Names Their Kid "Dude"?: Cielo Mágico literally means "Magical Sky"... it's pretty much impossible to be named like that in real life.
Ultimately subverted when it's revealed that she made up her name. Her real name, Angeles Inchausti, is much more realistic.
Zettai Ryouiki: She wore a lot of different skirts in season 1, much to Bauer's delight.
Nicolas Bauer is a worldwide famous archaeologist who travels the world in his continuous search for the island of happiness, Eudamon Island. While researching in Spain, he meets Malvina and they quickly start dating; when he returns to Argentina, they get engaged but then he meets Cielo. He also develops affection over the mistreated orphans, who see him as a fatherly figure, and treats as they were his own children.
One of the Kids: Behaves like this at times, specially around his son Cristobal, but with Monito as well. When Cielo disappears in the season one finale, he has less time for it, but his interactions with the kids still make him fit this trope to a T.
Only Sane Man: On the second season, specially while Cielo is missing and he's in charge of the orphanage.
Papa Wolf: Like Cielo, he's very protective of the kids. Specially of his son Cristobal, even if he's not his biological son, Nicolas loves him and would do anything for him.
Early in season one, he disguised himself as a Yamato Nadeshiko in order to give Cristobal time to steal a a clue to Eudamon Island.
And when he wants to visit Cielo in secret, he disguises himself as a nun.
Marianela "Mar" Rinaldi Tallarico
Marianela, commonly nicknamed Mar, is a young teenage orphan who was abandoned as a baby by her grandfather in a church. There, she was raised by a priest for her first years until he passed away, and Mar was sent from one orphanage to another, each worst than its predecessor. At the age of fourteen, she is taken in by Bartolomé and Justina, who immediately recognize her potential talent as thief.
Better as Friends: With Rama. They share one last kiss early in the second season before concluding they are better off like this.
Book Dumb: Not really her fault, as she went from one horrible reformatory to another and no one even bothered on teaching her how to even read. However, even after Rama teaches her how to read and write (and later Thiago and Cielo help her develop a little more), she still had a lot of difficulties.
This became a plot point in season 2, as it causes her to be held back one year behind.
Near Death Experience: In the first season, Bartolome and Justina kidnap her and then poison her, giving her a total of 24 hours left to live. However, Luz is able to gain the name of the antidote by threatening to kill herself, which causes Justina to give in said antidote, and together with Thiago they manage to get it to her before her last hour.
And again early in the second season, when a drunk Rama runs her over with a car. Luckily, CC saves her and Rama, since they needed them both alive.
Nice Hat: Had one during the mission to rescue Cielo's car, which only emphasizes her position as The Lad-ette.
Passing Notes In Class: In her entrance test to high school, Mar gets stuck in her english exam, where she was supposed to translate the song "Let It Be", and asks Jazmin for help through a note. However, she doesn't know either, but the guy who sat behind her did and, as he left to deliver his test, he left Mar a note with the song completely translated.
Unequal Pairing: Thiago is from a completely different class than her; he's rich and has traveled the world, while she's a poor orphan who lived in the streets and in orphanages, which makes the pairing quite uneven. It's what complicates their relationship all through the first season, but they don't personally mind their status...
Unkempt Beauty: Specially in season 1. As she later is freed from Bartolome's abuses, she gets the time to makes herself prettier, thus becoming a subvertion.
Rama is a fifteen years old boy and one of the orphans taken in by Barto. He and his younger sister Aleli were abandoned by their mother at an early age, who went to the United States in search for money and promising to return for them. However, the people who they left them with constantly abused them, so Rama took his sister and ran away only to be found by Justina.
Abusive Parents: While his mother was not abusive, she left him and Aleli under the care of some friends, who abused him and Aleli.
The Alcoholic: Surprisingly, in the first few episodes of the second season, Rama develops an almost-addictive fondness of alcohol, claiming that he missed out so much of life due to Bartolomé that he wanted to live it to the fullest. However, after a car incident which almost got him, Mar and Nacho killed, Mar is able to talk to him and calm him down.
Drives Like Crazy: Played with. In the earlier episodes of the second season, he drives like crazy due to alcohol. He later returns to his former self and gets better at driving... and later in the same season, Vale drives ike this while being chased by the police. Much to his dismay.
Red Oni, Blue Oni: The Blue Oni to Vale's and Mar's Red Oni. He could be considered in his relationship with Aleli for this trope, but it's unclear who is the red and who is the blue, as they sometimes seem to switch places on that aspect.
The eldest of all the orphans, Tacho comes from a poor northern town. His biological father sold him to a man from Buenos Aires (it was actually supposed to be his brother, but Tacho took his place). Once in the city, Tacho goes from one reformatory to the next until he is rescued by Bartolome. He dreams of a world where he is allowed to be a free teenager like any other, he enjoys theatre performing and catch fighting.
Twin Switch: As a small child, his brother was going to be sold to a man from Buenos Aires, but Tacho takes his place so that he doesn't have to leave their parents.
Two-Person Love Triangle: He is convinced that this type of triangle is perfect, since he'd get Jazmin however the trinagle ended, and spends an entire episode trying to prove this to Rama.
Walking Shirtless Scene: Season 2 has him without a shirt a lot, since catch fighters apparently don't need a shirt. Curiously, when Rama takes part of a catch fight, Rama keeps his shirt on.
A young and beautiful gypsy, Jazmin lived a happy life until her parents were murdered on her eighth birthday right in front of her. On her own since then, Jazmin was found by Bartolome and later sold at the age of thirteen to a gypsy slaver named Joselo. Two years later, Rama and Mar find her and (with the help of Bauer, Tacho, Cielo, Lleca and Iberlucia) manage to save her from Joselo... only to have her captured by Barto again, and return to the orphanage.
Dark Secret: In the second season, she starts using her gypsy powers to communicate with the dead, and she eventually suceeds. She does this with the aim of solving the murder of her parents yet she decided to keep it from the others, to keep them from worrying.
The Mole: She was forced into this by Barto in exchange for getting Tacho out of the worst Orphanage of Fear in Buenos Aires, where they hit the kids on a regular basis (and it's implied they raped them too), after she fails to rescue him.
The son of Bartolome with his former wife, Thiago is completely unaware of his father's activities. He arrives from London in the first episode of the series, where he was sent to study by Barto in order to avoid being discovered. Unlike his father, Thiago is kind-hearted and likes music; he also develops a great liking in Mar, much to Bartolome's dismay.
Horrible Judge of Character: Oh, so much. Not only with his father, but also when it comes to his love interests, as he dates almost every alpha bitch on the show without realizing how cruel they are to Mar, Jazmin or Caridad until it's taken too far.
Unequal Pairing: Mar is from a completely different social class than him; he's rich and has traveled the world, while she's a poor orphan who lived in the streets and in orphanages, which makes the pairing quite uneven. It's what complicates their relationship all through the first season, but they don't personally mind their status...
Would Hit a Girl: A rare example. After Mar leaves him for Simon, Thiago is so furious that he confronts Simon while he and Mar were playfully running. Angry at the scene, he throws a punch at Simon, but Mar gets in the way and gets it instead. But instead of apologizing, Thiago just says "the whole thing was her fault too, anyway". The others are not cool with it.
Your Cheating Heart: In the final episodes of the first season he confesses to Mar that he was with another girl during his trip to his grandfather's house. And it isn't until the second season that we learn that said girl was Melody.
Heel Face Turn: Towards the end of the first season, she gives up on Bauer and starts hating herself for all the pain she caused on them and the children, redeeming herself by taking Bauer out of jail and assisting him on defeating Bartolomé and Justina.
Heroic BSOD: While she's trying to decide who to side with, she spends days locked up crying, thinking of the things she has done.
She tends to acts like this towards the kids as from season 2 though, specially towards Cristobal.
The Mole: While on the run from justice on the first season, Barto and Justina force her to spy on Bauer and Cielo and inform them of their plans. Malvina attempts to subvert this by ignoring everything around her and not allowing the others inform her of the plans. Bauer later figures it out and protects her from harm, though.
Motor Mouth: And how! She can't stop talking, even in the worse situations.
Bartolome's right hand and the mansion's housekeeper, Justina is a dark middle-aged woman who dresses in black from head to toes. She is fierce and unscrupulous, and exploits the children without minding it... and actually enjoys it. In the second season, she does a Twin Switch with Felicitas and slowly begins changing for good while she poses as her cousin, Becoming the Mask by the end of the season.
Affably Evil: She's always in the line; sometimes she comes across as comical, sometimes she's cynical.
Yandere: She'd really do just about anything for Bartolome.
An adorable ten year old girl, Aleli is Rama's younger sister and Bartolome's favored victim, as he knows that's the other kids' (particularly Rama's) Berserk Button. She endures the pain just to lighten her brother's load and dreams that someday their mother would come and save them. She also develops a sisterly bond with Mar, who she views as her elder sister.
Shipper on Deck: In season 1, she notices right away that Rama is in love with Mar, and constantly gives him advice to get closer to her. She even admits to Mar that Rama has feelings for her, although she sort of said it on the heat of the moment.
She also ships Nico/Cielo from the very first episode.
On the second season, she and Luz start shipping Rama/Vale, even assisting her brother with his confession to her.
Street Smart: She didn't spend all that time on the street just observing, she knows her way through it.
Lleca (whose name is an anagram of the word "calle", which means street) is a young boy who was abandoned as a baby on the street, where he was found and raised by various other street kids older than him. He eventually found his way into the mansion, and is exploited like the others. Despite his young age, he knows his way through the rough streets and has various contacts which provide him with information whenever he needs it.
Street Smart: Possibly the one that fits this trope the best, as he was literally raised in the streets, and has many connections through them. Even characters who are Street Smart themselves, such as Tacho or Rama, often need his help with the streets.
A teenage girl who lives in one of Bartolome's fields, Caridad took care of the field along with her father until he passed away early in the second season. Bauer meets her while visiting the field, since he was now director of the orphanage, and takes her in at the orphanage. Due to her being raised in a rural area, her habits and costums are very different from everyone else's, which causes her to be bullied by the rich kids from the city, mainly by Melody and Tefi. However, Mar, Jazmin and Vale quickly become friends with her and accept her anyway.
Sex Equals Love: She is horrified by Matt's claim that sex was just sex and it shouldn't be a big deal. She even thought Jazmin had to marry him before that, since she's a firm believer that sex before marriage was not allowed.
Naked People Are Funny: When he meets Tacho and the girls in the bathroom on the second season, he sings them a bit of a song and lets go of the towel, his only piece of clothing left... causing Tacho to freak out and the girls to, well, stare...
Justina's secret daughter, who she has kept locked under the mansion's basement for ten years. Luz is innocent and naive, and believes (as she was told by Justina) that there is a war in the world outside the basement, where her mother fought bravely to keep her safe (which, in retrospective, was partly true). It is discovered eventually that Justina isn't her biological mother, Alba was, making her one of the heirs of the Inchausti fortune and mansion, as well as Cielo's younger sister.
Creepy Child: In the first season, while living in the basement.
Heck, even after that she has a few moments that make you realize she has a bit of a dark side. Probably the best example would be when she nonchalantly threatens to kill herself if Justina doesn't give her the antidore. With a straight face.
Cute Ghost Girl: When he first sees her, Lleca thought she was just this; a little girl too cute to be a ghost, but that seemed like one. He later learns he's wrong, though.
Used to Be a Sweet Kid: Yet thanks to CC, she's not anymore in season four. This gets later solved, though, when the cast returns from the future.
Mateo "Monito" Bauer
Monito was a young child who lived in a dumpster with an old man named Tulio, who he viewed as his grandfather. Justina, among discovering his talents for stealing, murders Tulio and takes Monito to the orphanage. He is cheerful and optimistic, even in the worse situations, and views Tacho as his older brother (mainly since Tacho promised Tulio before he died that he would take care of him).
Animal Motifs: Monkeys. Even his nickname, Monito, means monkey in spanish.
The Artful Dodger: He was quite happy with his lifestyle with Tulio because, despite living in the streets, they had one another. Justina understood that, which is why she chose to murder Tulio instead of simply taking him away.
Verbal Tic: "Pancho", which is an argentinean slang that could stand for "dude".
Bartolomé "Barto" Bedoya Aguero
The director of the orphanage Fundación BB, Bartolomé is a humanitarian and a gentleman to everyone, but that's just a cover: in reality, he exploits the young children in the orphanage, making them manufacture dolls and steal money from people, as well as being verbally and physically abusive. He is also desperate for money, but his late aunt's will specifically claimed that he should manage an orphanage and Malvina should be married for them to inherit (if the true heirs never appeared, that it), which is why he's quite anxious for Bauer and Malvina's wedding (and since Cielo's in between, he's not happy with her).
Justina's cousin who appears towards the end of season 1. She is immediately mistaken for her cousin, but soon it is proven that they're different people, much to everyone's surprise. Felicitas is kind and nice to just about everyone; the complete opposite of her cousin. As a child, they were raised together, but her popularity with boys earned her Justina's hatred. In the second season, she takes over as the new housekeeper.
A social worker who comes to evaluate the orphanage in the first season, and is eventually accepted into the family when Nicolas and Cielo take over the orphanage. She is religious and hard-working, but enjoys playing with the small children and taking care of them, serving as a sort of grandmother figure.
The mansion's gardener. Jasper is quiet and reserved, often keeping to himself and rarely speaking unless necessary. He's only loyal to who he considered his true master; Carlos Maria. He was killed by Bartolome when he wasn't able to kill Malvina.
Nacho is the son of a very important and very rich judge, which makes him believe he can do whatever he wants. In the first season, he is Thiago's best friend and becomes attracted to Jazmin. Nacho also enjoys tormenting Mar due to her being poor and parentless, something Thiago doesn't take very well. In the second season, he still keeps his jerk aspects but slowly begins changing upon meeting Caridad, who decides to bring out the golden heart burried so deep inside him. He is also the founder of the band Man!, which competes with the Teen Angels on every occasion.
Estefania Elordi, commonly nicknamed Tefi by everyone, joins the cast halfway through season one when Nacho sets up Thiago with her to get him over Mar. Thiago begins dating her and they get along well. She was adopted at an early age by Sandra Rinaldi and her husband, something Tefi takes no shame on. She is the first one to discover that Sandra Rinaldi is Mar's biological mother (or at least suspect it), and through she tries to hide it, it eventually comes out to light. Tefi hates Mar because she believes that she's trying to steal her mother from her, although deep inside, it is revealed that she really does love Mar, she just has trouble accepting her as her half-sister, but accepts her completely by the end of season 2.
Alpha Bitch: The main one in season 1, but in season 2 she's more of Melody's Girl Posse. Halfway through the second season, after admitting that she really loves Mar and patching up their relationship, she drops most aspects of it.
Simon is Thiago's best friend since their childhood, who was living abroad when the series begin. In the second season, he returns to the country and meets Mar in the summer camp... who mistakes him for a camp worker. He is very kind-hearted and shy, which causes him some problems opening up to other people, and is very often seen talking with his psychologist on the phone, even very late at night. He has a younger sister, Soledad, who has a special condition since birth, and he's quite protective of her.
Rich Bitch: To an extend. She disapproved her son's marriage to Alba, a simple maid, but towards the end of her life she calls her feeling sorry for her actions and names Alba (and her two daughters) heirs of her fortune.
Nicolas's son, Cristobal is an incredibly smart ten years old boy who loves archaeology and history. He has lived his whole life abroad, following his father from quest to quest, and like him is curious to discover the truth of Eudamon Island. He is actually the son of Iberlucia, with whom Carla was having an affair at the time, but when Carla gains custody of Cristobal he decides to allow Nicolas to keep raising him as long as she's always allowed to visit.
