|“||I finally get to meet you. The person behind the glass. I'm glad. I wanted to thank you.||”|
Number 3 was brought as a young toddler to the , one of a handful to be spared , only to endure ruthless experimentation instead. In captivity, she bid her time and hid the true power of her vectors during the that were performed on her, including having iron balls fired at her head. One day during feeding time, she surprised the guard and scientist who were handling her with her true potential. She killed facility personnel, but became curious when she met , having seen and heard him from behind the glass partition when she was experimented on, perhaps driven by the sympathy in his voice, regarding her plight. In a haunting manner, she told him she had wanted to meet him and wished to thank him. Right as her vectors brushed his forehead, she was shot and killed by with an armor-piercing bullet. Her personality was outwardly innocent, but easily turned homicidal, and was capable of clever deceit. She felt justified in her rage by how often she begged the scientists to stop their cruel experiments, a plea that only Kurama heeded.
Some months later, Kurama realized to his horror that Number 3 had infected him (and his lab assistant, Oomori) with the Diclonius virus, leading to the birth of his Silpelit daughter, Mariko. Having wondered, even before this, about the geographic concentration of the birth of horned girls and the time-frame of these births, Kurama came to the conclusion that there was a 'Queen' Diclonius, leading to the discovery of Kaede. Among the evidence leading to this conclusion was the fact that her mother gave birth to Diclonius twins four years after her birth, confirming the existence of an original infecting party.
As a Diclonius, Number 3 had vectors. They were estimated to be about one to three meters long.
- Several fansites give Number 3 the name, "Sanban," and state that she is the older sister of Nana. Neither the manga nor the anime contain any such stated or implied connection between them, nor do they give her a name (Sanban is Three in Japanese, just as Nana is Seven). This idea appears to be merely fanon or speculation. While it is also possible that this was an unstated plot idea by Lynn Okamato, again its lack of in-series confirmation means that, for the purposes of this site, it will be noted but not treated as canon. While certain plot elements do possibly point in this direction, it also possibly creates an age discrepancy for Nana. The ARMS Elfen Lied Official site is often brought up as the source of this information. It is located here but is only in Japanese.
- Like Aiko Takada, Number 3 is a relatively minor character with disproportionate impact, connecting the storylines of Kurama, Mariko, Hiromi, Nana (directly or indirectly), and leading, by way of inference, to the realization of the existence of Lucy.
