Yami/Plot

Background
There is not much background information on Golden Darkness until she opened up to Rito. She is a living weapon created by Dr. Tearju; who named her Eve and raised her like a younger sister from when she was little, Eve was a happy little girl who looked up to Tearju. Tearju would always read a bedtime stories and cook for her little sister and despite the food being badly made Eve would still force herself to eat it. Until the organization that had Tearju create Eve took her away to be trained as a weapon renamed Golden Darkness and tried to have Tearju killed. Tearju escaped but was separated from Eve and couldn't find her until they meet again on Earth in To-Love-Ru Darkness. The organization was destroyed by the hitman Black (a character based on Train Heartnet, the main character from Black Cat), setting her free.

Tearju is also the name of the scientist who created Eve in Black Cat, whom Yami is based on. The connection between the two is also strengthened 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. Yami had fought and mercilessly defeated the assassin called Tyrant Azenda because of a dispute within the assassination organization they both worked for.
