Lala Satalin Deviluke (ララ・サタリン・デビルーク, Rara Satarin Debirūku) is a fictional character of the manga series To Love Ru, created by Saki Hasemi and Kentaro Yabuki.

In the series, Lala is an alien princess from the planet Deviluke who, to avoid marrying one of her marriage candidates, decides to run away from home to Earth, where she pretends to be in love with the human boy Rito Yuki to prevent marriage, but falls in love with him after misinterpreting a statement made by Rito to another girl.

Reviewers have complimented the character's personality and physical attractiveness, although her diminishing role in To Love Ru Darkness has been criticized.

Lala is a highly attractive teenage girl with a curvaceous figure, long pink hair, and emerald green eyes.

[5] Lala is shown as a girl the same age as the other characters, but with a rather childish personality: she is impulsive and acts instinctively, without thinking about the possible consequences.

Over time, on the other hand, can be witness an evolution of Lala's character, due to the proximity to her fiancé Rito Yuki and his friends, which leads to a maturation, mainly from the sentimental point of view.

[8] Like all citizens from Deviluke, Lala has a distinctive tail with a shape of a spade on the end that can shoot a destructive beam.

Despite her childlike personality, Lala's intellect is perhaps one of her most remarkable abilities, being capable to create extraordinary inventions as well redesign other material objects; her planet even wanted to use it for weapons research and engineering.

[3] While on the run, Lala randomly teleports naked to the bathtub of human teenage Rito Yuki while he is taking a bath.

Lala hastily decides she wants to marry Rito to stay on Earth, much to his dismay, and Zastin proceeds to attack him.

[19] In the anime adaptation of To Love Ru, when Lala shows up in Rito's bathtub, he accidentally grabs her breasts, which, to his dismay, is considered a marriage proposal on the planet Deviluke, and to annul the engagement, Rito must grab Lala's breasts again within the time limit of three days, which he fails to do so.

7:85 (ja)] The June 2015 issue of Shueisha's Jump Square magazine included the results of its popularity poll for the heroines of To Love-Ru Darkness.

[34] In a review for To Love Ru, Theron Martin, from Anime News Network, called Lala an "irrepressibly cheery airhead", while also complimenting her as a "damn fine-looking naked", saying the series gives ample opportunities to appreciate that, in addition to outright declaring Lala the sexiest girl in the series.

[35] In a later review for To Love Ru Darkness, Martin said that Lala as the female lead was "undeniably fun to watch", commenting on how her bubbly personality and gorgeous curves delicately balanced her sexy innocence, airheaded genius, and childlike exuberance with a more mature romanticism.

However, Martin also criticized the fragility of that balance, pointing out the necessity of keeping it on a comedic focus also left virtually no room for character development.
