Yami enjoys spending her time reading books and magazines whilst eating taiyaki. Yami also claims to despise 'ecchi people', especially Rito, though she gradually begins to develop feelings for him later on. However she was actually appointed by Lacospo who is one of Lala's suitors, to assassinate him. She uses this as an excuse to remain on Earth, in order to be closer to Rito. Being an alien, her physical strength is excessively powerful, more so than the average human, so when a perverse move is made on her by someone, she uses this to her advantage and pulverizes them.
A dispassionate, withdrawn assassin, Golden Darkness is hired by one of Lala's arranged suitors, Lacospo, to kill Rito, until she breaks the contract, noting the true nature behind her target. Golden Darkness came on a ship called Lunatique which is very quick (reaching a planet 30 million light-years away in 2 hours). Golden Darkness is currently staying on Earth, roaming around the city streets and Sainan High, with a motivation to continue her duty to assassinate Rito, although she has yet to accomplish this (hinting she only said this as an excuse to stay on Earth, which is then confirmed). Commonly referred as "Yami-chan", she spends her time reading books and magazines, while eating taiyaki (it is the only thing she eats on Earth since it is the first food offered by Rito, prior to spending a night at the Yuuki residence for a sukiyaki dinner). By her planet's (Kurosu) calculations, she is 24 years-old, despite having the appearance of a 14 year-old (her Trans ability has slowed her ageing process), although this is only mentioned in the anime and has a weakness towards anything slimy. Like Lala, Golden Darkness' physical abilities are exponentially stronger than a human's. She states she hates "ecchi" people, and does not hesitate to assault a person who looks at her in an obscene way.
She has become close to Mikan Yuuki and seems to have developed a sense of protection for her, evident when she and Mikan switched bodies and the Principal attempted to grope her, to which she menacingly told him not to touch Mikan and delivered a savage beating. Though she always says she will kill Rito one day, it is doubtful she will ever do it. In fact, as of chapter 159, she seems to have begun to develop feelings for Rito. Instead of beating him and saying "I hate ecchi people" like she normally does, she blushes when Rito saw her in a swimsuit and stated "Don't look at me with those ecchi eyes". In To Love-Ru Darkness, after some convincing from Mikan becomes a classmate with the rest of the class as well as takes cooking lessons from her. Despite her normal emotionless appearance, it is easily noticed that she does care for Rito, and is shown to be developing further feelings for him but is still brutal and hostile when he becomes "Ecchi" in her eyes. However, her new life may already be in jeopardy when Mea, a classmate, is revealed to be her 'little sister', suggesting she return to space and to kill Rito. Recently, it is revealed that Golden Darkness's creator is named Professor Tearju and her given name is Eve.
