Lala Satalin Deviluke

Lala Satalin Deviluke is the main female protagonist of the story. The story begins as Lala runs away from home, as she does not wish to get married to any of her suitors, and due to an accident, ends up naked in Rito Yuuki's bathtub. Upon arriving on Earth, Lala pretends to love Rito to keep herself from getting married, but really does fall in love with him after she misinterprets a statement that Rito shouts in self-defense.



Appearance
Lala is a highly attractive teenage girl with long bubble gum pink hair, emerald green eyes and curvaceous and often referred to as perfect figure. Her most distinguishing feature is her tail which extends down from the base of her back. Her tail is long, thin and ends in a spade like end. At the beginning of the series she is seen almost always in her costume robot Peke in what can only be called an enlarged version of Peke himself (see above). Wanting to fit in more among the people of earth, she now has Peke dress her in various earth styles; she has also has bought herself a large number of earth clothes for when she is out of energy.

Personality
She is incredibly enthusiastic about the smallest things and has a very bubbly and slightly child like nature most likely the result of being raised as first princess of Deviluke. By appearance she can be considered a bit air headed but is known for her genius level intellect as can be seen in her amazing array of inventions, her planet even wanted to use her for weapons research. She is very caring and generous and appears to have a need to make everyone she cares about happy. She is very naive about earth culture and will often make highly dangerous mistakes.

Despite her naturally cheerful and somewhat childish nature Lala is not as emotionally immature as she would appear. She has on rare occasions become upset and angry at other characters even Rito over real issues. One incident in particular involved her spending the night with Haruna because Rito had yelled at her and it made her doubt if her affections could ever be reciprocated. One great demonstration of her emotional maturity was when during the Trouble Quest incident her sisters were trying to force Rito to admit his feelings for her but when seeing the stress he was under stopped them having already found out that he does like her in some way.

She has also shown an amazing level of compassion for other characters. One example of this is when Haruna admits to her that she is also in love with Rito she not only moved out of his cupboard in favour of an a joining house in the roof but also stopped throwing herself at him to hug him in order to be fair to her and make it easier on her.

Due to never really being alone her entire life, she has no notion of modesty and is more than happy to walk around naked (much to Rito’s disdain) but has in more recent times gotten better at knowing when and when not to be naked, though she still makes a habit of walking out of the bath room naked when she needs something. It can be pointed out however that although Lala holds no real issue with appearing naked around people, more so in recent times; she is in no way perverted or in any way interpreting the action as sexual. She actually is for once very bashful when it comes to being touched or viewed in a sexual way or from any overly compromising angle, as Rito found out after she landed on top of him when they were on their way to save celine but for once was incredibly embarrassed about this.

Childhood
=== === As the first daughter of King Gid of Deviluke and her unnamed or seen mother, Lala was born the first princess of the planet Deviluke. She has two known siblings, the twins Nana and Momo, that she is very close to. As a child she was friends with the Memorze royal Run/Ren, though she seemed to prefer Run who she used to unknowingly torment. She is known to have had an at least pleasant relationship with her father as she warmly tell Rito of a time that she was lost in the forests of Deviluke and her father found her and took her back to the palace on his back. It was not that long after this that she built Peke the costume robot that for one allowed her to fly and two gave her a permanent friend to always be with her. As first princess and presumed eventual successor to the throne of Deviluke, it appears that in order to do this she must marry so that both she and her spouse can rule together. As such she was continuously presented with male suitors, all of whom she has turned down. When she finally couldn’t take it anymore, she escaped from her home to earth so that she could have some control over her life

Powers and Abilities
Being an alien, Lala has strength and power far more powerful than the average human. Her physical strength (without any inventions or powers) surpasses any human on Earth, and even maybe some aliens in the solar system.

Her weakness is her tail. On Planet Deviluke, female's tails are far more sensitive than male's. Anytime someone touches Lala's tail, she becomes weak and seems to lose her strength, though she can shake anyone off of her tail with astonishing strength.

Lala's main method of combat (and sometimes life) are her many inventions. She is considered a genius and has made many inventions. However, a running gag in the plot is that her inventions usually do not work as well as Lala and the others would hope. A list of some of her inventions and their functions are as follows:


 * Pyon-Pyon Warp-kun: This invention allows any living person (or "unit", as used by Lala) to warp a short distance, though you cannot specify the destination, making you warp to someplace random. After you use the ring once, it will take a whole day for it to recharge its energy for use. Another setback is that Warp-kun can only warp the person, not their clothing, meaning that when the person warps to a random place, they are completely naked. However the DX version has been modified so it can transport people and clothing but unfortuantely when it teleports someone, the machine itself stays at the place of the original teleportation.
 * Go-Go Vacuum-kun: This invention works exactly like a vacuum; it sucks things up inside it. However, the power of this vacuum is so great, it has the potential to suck up anything in its path.
 * Sniff Sniff Trace-kun: A robotic dog that can sniff out anything with a trace. However, he has a tendency to wander off if he smells another thing that has a nice scent.
 * Slosh Slosh Warp-kun: A toilet-like machine that warps a creature to another planet by "flushing" them down the machine. It seems to work just like Pyon Pyon Warp-kun, as it transports a living thing to a random place, but the creature still has their clothing and it does not need a whole day to recharge.
 * Change Boy Girl-Kun: A gun-like machine that can change a boy into a girl, hence the name. Unfortunately it has a time limit so changing back into a boy in public can be embarrassing.
 * Maru Maru Change-Kun: A Machine that switches the bodies of two people. only three times has this invention been used in the manga, The first was when Lala switched Rito and a stray dog, then Lala switched bodies with Haruna, and lastly Yami and Mikan switched bodies for a day.

Relationships with Other Characters
Lala has experienced many friendships in the story, some stronger than others. Aside from her family and royal bodyguards, here are her connections to her peers.

Rito Yuuki
In the first chapter, Lala only pretends to love Rito so that she can stay on Earth and escape her marriage suitors. However, after he saves her (or better yet tries to save her) from Zastin, she states that she really does love Rito and wants to marry him. Throughout the story, she openly shows her affection to him, even going so far as to walk around his house naked, hoping that she will win his affection.

When Haruna tells Lala that she also loves Rito, her showing of affection toward Rito decreases for a while, but then decides to support her own love and goes back to openly showing her affections for him.

As the story has developed her love for Rito seems to have matured greatly and is not as insane as it has once appeared. Her (somewhat) calmer attitude around him has allowed them to develop a closer relationship and are in many cases found together in most cases with Rito's prior consent. A clear example of her maturing love is her exceptance that Haruna, her best friend, also loves him and that she would fight for him but be happy for her if he chose her instead.

It was not until the last chapter that Rito finally told Lala that he loves her. She was also overjoyed when she heard that he loves Haruna as well.

Haruna Sairenji
Lala regards Haruna as her best friend and will often go to her for advice when she is not sure about some part of Earth culture or Rito. After, Haruna reveals to Lala that she too is in love with Rito as well. This knowledge causes Lala much guilt over how she has acted around Rito over the last year and how that must have made Haruna feel; she even tries to distance herself from him in an effort to make Haruna feel more comfortable.

Later after contemplating a while she confronts Haruna and declares herself her official love rival for Rito. She has since reverted back to her over the top method of displaying her affections.

Mikan Yuuki
Lala thinks very highly of Mikan, mostly because she lets her stay in her and Rito's house and Lala loves her cooking.

Lala and Mikan are very good friends and Lala always tries to help her with chores (even though she messes up the chores most of the time).

Golden Darkness (Yami)
Lala considers herself a friend to Yami, going so far as to helping her pick out new clothes (Chapter 61), and helping Yami realize how nice Rito really is by letting Mikan and Yami switch bodies for a while (Chapter 139).

Yui Kotegawa
In many ways Lala and Yui are each others negatives even in appearance, Lala being pale skinned and colourful while Yui is tanned in complexion with a darker image. They are friends even though Yui does hold some resentment over Lala's lack of decent behaviour and to some level jealousy over her closeness to Rito who she is also in love with.

Lala likes Yui a lot and often tries to find ways to include her in things that they are doing. While others have a tendency to view Yui in a formal and in many cases resentful light Lala does not though due to her nature it is doubtful she would view anything that she would do as bad.

It can be considered ironic that when even a comparison of girls figures is brought up by Haruna or any of the other characters she and Lala tend to be brought up as examples of what other girls wish to achieve as the two are considered to have the best bodies. It can also be viewed as ironic that even though these two have the best bodies they are the only two so far seen that pay no attention to how they look.

Saki Tenjouin
While Lala tries to be friends with everyone, a girl named Saki Tenjouin holds a grudge against Lala. Saki used to be the most popular and beautiful girl in school, until Lala showed up and attracted all the attention. Saki goes so far as to go naked, set up booby traps, and even shoot Lala with mustard to try to humiliate her. Most of her antics usually backfire. Lala is mostly oblivious to the fact that Saki really doesn't like her, and is still friendly to her.

Ren/Run Elise Jewelria
Ren

When they were children, Lala would always dress up Ren as a girl and call him a crybaby. Lala would perform disastrous experiments on him, and test out her inventions on him. Despite this, Ren is in love with Lala. One day, Ren asked Lala if she would marry him, she replied she would if he would become manly. Upon arriving to Earth, grown up a little, he desperately tries to prove to Lala that he has become manly, and trying to one-up Rito. However, Lala really doesn't care too much about Ren's feelings and only wants Rito.

Run

While Ren is deeply in love with Lala, Run is one of the few people who despise her. She never forgave Lala for tormenting her as a child and holds a deep grudge against her. To make things worse, Lala has Rito, whom Run falls in love with. She, much like Saki, goes to outrageous extremes to try to humiliate Lala. And, they usually backfire as well.

Mikado Ryouko
"Mikado-sensei", as the kids will usually call her, is the high school's nurse and one of Rito's and Lala's personal friends. By the time when Lala had her strange flu it was eventually revealed that she in fact is also an alien and provides exotic herbs and treatment methods originally intended for other aliens that live amongst Earth inhabitants, unbeknownst to most of those.

Most of the time she is very sexy and/or scantily-dressed and her behaviour doesn't leave much room for speculation whether if or not she is somehow kinky and/or perverted herself, as she, for instance, openly teases her young patients (like Rito) sexually, going even so far as to provide the girls with "special medicine" or advice on how to seduce him behind his back. She is very well-built and buxom and has by far the largest bust of the entire female cast.

Kenichi Saruyama
Lala and Saruyama are not seen together too often. They are friends, but Lala is totally oblivious to the lust Saruyama has for her. Lala knows that Saruyama likes Riko (Rito as a girl) and even helps him out by turning Rito back into a girl and making him/her go on a date with Saruyama.
