Nana Astar Deviluke

Nana Astar Deviluke (ナナ・アスタ・デビルーク) is the twin of Momo and the younger sister to Lala. She is the second princess of Deviluke. She has the ability to speak to and understand animals. Out of all the main female cast, she has shown the least attraction to Rito, regarding him as a "Beast". Even so, she has shown slight affection to Rito, with the notion that she had tried to sleep in his bed with him. In To Love-Ru, she used to be seen with Momo all the time, but in To Love-Ru Darkness, they are not together as often as before. This is because while Momo becomes more attached to Rito, Nana became friends with Kurosaki Mea, whom she hangs out with more often. Although Mea is a transformation weapon and has difficulty accepting the notion of friendship, she eventually becomes more open with her feelings to others through her friendship with Nana.

Appearance
Nana has long pink hair and purple eyes. In both To LOVE-Ru and To LOVE-Ru Darkness, Nana usually has pigtails at the sides of her head. She sometimes loosens the pigtails such as after bathing or when she is wearing casual clothes.

Like all Devilukeans, Nana also has a long black tail at her back, and like her sisters, she has a spade-shaped tail end. Nana also has a smaller bust than Momo which she is teased about by Momo. When Nana is fighting, her pupils become thinner and pointed. Another interesting note is that she has a pointed fang on the left side of her upper teeth making her the only Devilukean princess that has a pointed fang in her mouth.

Nana wears her unique attire of black collar with yellow ornament, sleeveless dress and sleeves reaching below armpits from hands, thigh-high socks of black and red stripes and black shoes. The attire generally consists of black and red colours, as contrary to her twin sister, Momo's, but it just differs from colouring, as Momo's is black and green-coloured.

She wears the uniform of Sainan High when she attends to. In the early chapters of To Love-Ru Darkness, she also wears black socks and the yellow waistcoat as Momo and other students wear, but later on, she does not wear the waistcoat over the uniform and changes her socks to white, loose and shorter ones.

Personality
"You Beast!"

- Nana to Rito Nana is short-tempered, impatient and somewhat tomboyish, much unlike her twin sister. But underneath her brash, overactive and angry behavior, Nana is actually very kind, helpful, cheerful and even loving. She has an open, sincere, and somewhat childlike side of herself that makes her cherish her friendships very much, which also makes her easily heartbroken when those friendships were ever lost or betrayed, such as with Mea, whom she considers her first true and closest friend.

Despite her tomboyish personality and temper, Nana has her vague charm that has even impressed some of the most mindless of individuals. Mea is an excellent example of this; When Nana was talking about how the two birds were going to fly west, Mea was astonished and amused when she found out that Nana could talk to animals, being fully accepting of this odd trait. Before, Mea has been just a mindless being that was sent to Earth. Before she met Nana, Mea was following Nemesis's orders without question. Because of Nana's "charm", Mea has opened up since and has become best friends with her.

She can be very brave whenever her friends are in trouble, such as when she risks her own life just to save Haruna and her dog, when Mea is trying to scare her away, or when a little monkey is about to get hit by a truck.

Nana hates being teased by Momo because of her flat chest. While Momo possesses a developed figure similar to their elder sister and mother, Nana is far less developed and is very sensitive about the fact. Momo passively and playfully teases her about it, but Nana occasionally becomes upset and even hurt about it. She has also been described as something of 'uncareful', as she was apparently the kind of child who would often break her toys by mistake, and even still manages to get most of her belongings, and sometimes other people's, disjointed or improperly used.

Nana seems to dislike anything lewd and impure, mostly referring to Rito and calling him a beast because of his bad habits. Ironically, she initially didn't know what sex actually was, often thinking about how baby animals keep showing up in her virtual safari. After being told of the process, her reaction became a source of teasing for Mea. Originally, Nana was one of the few girls who didn't have any feelings for Rito, but eventually his kindness starts to grow on her, like when he helped her rebuild her friendship with Mea and hugged her in the process, which she remembered felt very good. Because of this, Nana has developed a tsundere side to her when it comes to Rito. Sometimes when she is denying something, she makes a certain outburst (mostly involving Rito), and her pigtails seem to rise up.

Nana slightly matures over the series, as pointed out by Momo, and grudgingly notes that Nana might be surpassing her. When Lala was attempting to kiss Rito, Nana advises her that Rito has some complicated thing he needs to deal with first before the kiss. This shows that Nana has some concern over how Rito might be feeling. And because she avoids and denies love most of the time, she has taken more time to think about and examine her own feelings more carefully, which gives her a better understanding of how Rito feels about his complicated relationships at the present, and she may understand love better than even Momo. She does, however, think that couples are supposed to kiss AFTER they are married.

Even so, she does seem to be quite shy and graceful at times when necessary, most likely due to her being raised as a princess.

History
Ever since childhood, Nana and Momo always fought. Whenever they would fight, their older sister, Lala, would always make a way for them to make up, and for Zastin not to be angry with them. An example of this is when they were children, and Momo and Nana were fighting. Zastin scolded them for fighting, but Lala caused her inventions to run amok, then asked for Nana and Momo's help to catch them, so that Nana and Momo will work together, and so that Zastin would direct his anger towards Lala instead.

It was also seen in her past that she tried to break the mold and be different. This can be seen in her skills at art which are not very good. Rather then take in the lessons from her teacher she would go her own way and develop her own artistic style.

At some point, Nana traveled through space and met tons of animals she befriended due to her ability to talk to them.

Powers and Abilities
Devilukean/Charmian Hybrid Physiology: Like all Devilukeans, Nana's physical skills are greater than any known race. Her's in particular, because Nana can be very athletic, as she is very good at sports, even being asked to join Sainan High's swimming club. Nana also possesses the Devilukean's super strength and their bloodlust, making her very dangerous in battle. However, her most notable ability is communicating with all animal life, it is revealed that this is a result of having Charmian descendants from her mother mixed with her Devilukean blood.
 * Superhuman Strength: As a Devilukean, Nana possesses incredible strength, even able throw an actual person (often Rito) a great distance.Nana_Tail_attack_v2.png
 * Devilukean Tail: Like her sisters, she also has the ability to shoot lightning out from the tip of her tail, when using this ability in tandem with with Momo's, it creates an even more powerful lighting shot. Also like her sisters, Nana also becomes weak whenever someone touches her tail. This weakness is usually taken advantage of by Momo whenever they get into fights.
 * Zoolingualism: An ability unique only to Nana. She shares a connection to animal life since she was born, being able communicate with them, though this doesn't seem to be the case with animals with low intellect.
 * Expert Xenoecologist: Compared to both her sisters (and perhaps most characters), Nana is the least smart in comparison, even in Earth history. However, she is an expert on most animal biodiversity in the galaxy. She is very knowledgeable in the habitats and lifestyles of many species in the galaxy, and is able to customize and maintain the ecosystem in her cyber safari so that all her different pets from various alien sources can co-exist together. Strangely, she was unaware of where babies come from until recently.
 * Strong Will Power: She has great will power since she is the only person able to resist Mea's Psycho Dive which is shown twice.

Equipment
D-Dial: An invention with the same functions as a regular phone, however, her D-Dial is capable of summoning animals that she has met throughout space, whenever she needs them from her virtual Cyber Safari.

Anti-Gravity Wing System: A small chip placed at the back of most of her clothes that gives her a pair of devilish wings on the back to enable flight. This is an invention made by Lala.

Etymology
Like the other parts of the Devilukean family, Nana's second name is a reference to the demon, Astaroth, who was one of the three superior spirits (or the Unholy Trinity) of Hell, together with Lucifer (Satan) and Beelzebub.

Trivia
