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. 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.

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. 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, a child-like figure but she can change her appearance to look older with her transformation ability and is famous for her all-black gothic-style signature outfit.

Personality
Though she does come off as stoic, emotionless, and withdrawn in actuality she is pretty kind, but don't say something she doesn't like because she will attack you then... She also hates perverted people and normally attacks Rito who by his clumsy nature trips in to her and gropes her or the principal whos 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. Nano machines that circulate through her body allow her to do this wonder. 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, she becomes extremely weak and cannot 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.
 * 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 verison 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 along with Momo replace Lala and Haruna as the main heroines though Lala and Haruna are 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
