Yami

Golden Darkness (金色の闇 Konjiki no Yami) also know as Yami is a major character in the To Love-Ru anime and manga series. She is a lonely assassin who is initially hired by Lacospo, one of Lala's arranged suitors, to kill Rito Yuuki. As she spends more time on Earth, she builds a very strong relationship with Mikan Yuuki and maybe even Rito himself. She bares a resemblence to Eve from the manga series Black Cat another series by Kentaro Yabuki.

In To Love-Ru Darkness, Golden Darkness has become the main character. In this story-line, there is an evil organization that wants Golden Darkness to kill Rito and join their ranks and turn Golden Darkness into the same heartless assassin she once was.

It has been revealed that according to other assassins, Golden Darkness has fought as though she was an emotionless automation. Now however, Tyrant Azenda stated that Golden Darkness was pretending to have friends and she was smiling. Golden Darkness has been shown to be a heroine and one, this is because she tried to save Mikan from Tyrant Azenda, even going to the point of sacrificing her own life just to save her.

She also tells Rito her past, she talks about her creator, Dr. Tearjou Lunatique and how the evil organization tried take advantage of Golden Darkness but the evil organization collapsed. She also talks about how King Gid Lucion Deviluke triumphed in the Galaxy's Unification Wars. She has shown some form of affection towards Rito because she snuggled up next to him and she said, "Good night" to him. Though it is clear that she is very confused about how she feels about him.

Her "sister", Mea Kurosaki (a product of the same program that created Yami), has been sent to Earth to take Golden Darkness away and revive the old heartless/murdering self that Golden Darkness once was.

Golden Darkness has defeated the assassin called, Tyrant Azenda who came to earth to get revenge on Yami for destroying her reputation, Unable to defeat her normally she takes control of Mikan and uses her as a weapon/shield against her. Luckily however before Yami had to sacrifice herself to save her friend, Momo came to the rescue while looking for Rito and Mikan. Momo summoned a cannon blasting plant that knocks Tyrant Azenda out cold. The evil Tyrant is then arrested by Commander Zastin.

Throughout the story line, Golden Darkness realized that when she's in trouble, it will be her friends, and not herself, she can rely on; however, she states that she can't rely on Rito Yuuki.

Background
There is not much background information on Golden Darkness. She is a living weapon created by Dr. Tearju; information on her time with this doctor has not been given; Tearju is also the name of the scientist who created Eve in Black Cat, who she is based off of. The connection between the two is also strenghten by the fact that her given name is also Eve. Before she met Rito and Lala, she lived in the universe alone, doing her job as an assassin. There is also information that she has met and fought the hitman Black, though we do not know who won or lost.

Appearance
Yami is described as having long blonde hair, dark red eyes, and a child-like figure. Although it should be noted that she can change her appearance to look older with her transformation ability, her choosing to remain in her child-like form is most likely due to the fact that it is comfortable when in combat. This can be seen in both the manga and OVA where she wonders on whether or not having larger breasts and a more mature body would affect her balance. She is additionally famous for her all-black gothic-style signature outfit, and characters have made several notes about the shape of her thighs throughout at a few points in the manga--most notably the principal, who makes the remark during their first meeting. Of course, this was all before they were pummeled into oblivion by none other than Yami herself.

Another notable aspect of her appearance are her hair clips on each side of her head which give her a cat-like appearance, possibly paying homage to the illustrator's earlier work, "Black Cat", in which her character design also originated.

Personality
Though she does come off as stoic, emotionless, and withdrawn in actuality she is pretty kind, but she would attack people who talks about something that she doesn't like. She also hates perverted people and normally attacks Rito who by his clumsy nature trips in to her and gropes her or the principal  who's perverted nature makes him come running to her in almost no clothing whenever he see her. She also has a weakness towards anything slimy. She had been contracted to kill Rito, but after their initial meeting she chose to 'assess' him. Since that she has begun showing small inklings of feelings towards him.

Powers and Abilities
Golden Darkness' signature ability is her transformation ability. This ability allows her to turn her body parts into various objects, preferably weapons or tools used for combat; the nanomachines that circulate through her body allow her to do this. She usually uses her long hair for transformation, occasionally using her arm and feet. A few examples of her transformation capabilities are:

A downside to her powers is that if she uses her power excessively, the nanomachines in her body overheat, leaving her extremely weak and unable to move. (she even passes out and goes seemingly unconscious). Rito had to carry her to Mikado's house to restore her strength (Chapter 45). Yami states that her power is a "cursed power" and that it can only be used for hurting people (this statement is quickly dispelled however, when Lala asks her to help cut up tofu and she transforms her hair lock into a blade to cut it, making it very useful for other things) (Chapter 76). Apart from her alien powers, she also has excellent martial arts skills. Her physical combat skills nearly match her transformation power, meaning that even if her transformation powers were taken away from her, she could still win a fight with just her brute strength, as shown when she beats the school principal while in Mikan's body only using kicks and punches.
 * Transforming her hair locks into: giant fists, dragon heads, and swords.
 * Transforming her arm into some sort of an arm blade.
 * Transforming her feet into spiked, wreaking ball-like objects that can crush the ground.
 * Transforming her body into a older version of herself.
 * Transforming her hands into a set of bladed claws, sword, and hammer.

Rito Yuuki
When she first meets Rito, her assignment is to kill him; Lacospo, one of Lala's suitors, hired her for the job. However, after learning that Rito is not what Lacospo described him as, she turns on Lacospo and spares Rito, but still claims that she will kill him eventually and will stay on Earth until her mission is complete (though the job is technically over). Later, she actually confirms to Rito that she only said that as an excuse to stay on Earth, and warns him not to make her too angry. This suggests that she wants to stay on Earth with Mikan and Rito. (Chapter 138) As time passes, Yami seems to grow some feelings for Rito. He carries her on his back and runs to Mikado's house to restore her strength when she overuses her powers, he saves her from another assassin that was hired to kill Rito by Lacospo, and, unbeknownst to him, he shows her a nice side that makes her blush and even envy Mikan for being so close to him. Yami hates it when Rito sees her naked or changing, and she never hesitates to use her transformation powers to hit him with a powerful punch to the face.

Mikan Yuuki
Yami's most significant friendship is with Rito's younger sister, Mikan Yuuki. This may be because of Mikan's frequent friendly advances on Yami, and Mikan constantly talking with and helping Yami. In Chapter 139, her and Mikan switch bodies for a while, both wanting to see what the other's life was like. Mikan is the only person Yami actually calls "friend" and is seen by her side quite a lot, and vice versa.

Lala Satalin Deviluke
Yami is forced to fight Lala when she is assigned to kill Rito. After they stop fighting, they become friends (at least in Lala's eyes). As of Yami's opinion of Lala, she seems oblivious to Lala's friendly behavior towards her, but she never attacks Lala or says anything bad about her after their fight.

Story Role
Yami is one of the most popular and main characters, aside from Rito, Lala, and Haruna.(this is probably because she is an almost perfect copy of Eve from Black cat which was also made by To Love Ru's illistator Kentaro Yabuki) She appears regularly in the To Love Ru series but not in every chapter. This changes though in the spin-off series To Love-Ru Darkness where she replaces Lala as the main heroine though Lala is still seen abit less often. In the anime, she appears in a few episodes, including all of the OVAs. To see chapters where Yami is present go here: To Love Ru Manga Chapters.

Yami made her appearance in Mayoi Neko overrun in chapter 7 page 27.
