Personality
She is described as someone that is naive, not kind, and this can be attested to the fact that despite trying to know each and every one of the Sister clones, she still has them perform an experiment that they will not walk out alive in, or allow Accelerator to continue to walk a path of blood despite him still being a child. She is described as doing things for her own welfare instead of genuine concern for others, and ways the risks and rewards of the decisions she takes.

However, she is someone who desires to change her ways, and become kinder. She has a cool head, and doesn't force others to do what they should do, and can be considered as an older sister, or a parent to Accelerator and Last Order.

She also has a habit of collecting things that the changes the body in quality.

Background
Little is known about her, except that she wanted to be a kind teacher but became a researcher instead. She later becomes a researcher for the Level 6 Shift, and was concerned with the manufacturing of the clones and of Last Order, as well as the maintenance of Accelerator. In her naïveté, she names all the clones in the experiment, and was as well, apparently, the one who chose their panties.

She also has a lifelong friendship with Yomikawa Aiho, though it is unknown how much she knew of her involvement in the Level 6 Shift. She also seem to have knowledge of the amazing skills of the Heaven Canceller.

She was the first adult Accelerator trusted due to the fact that she put a stop to an experiment that would have killed him when he was a kid.

She guides Accelerator throughout his operation to retrieve Last Order, as well as during his operation against Amai Ao, who has capture her. She shows her practical side by telling Accelerator to kill Last Order, as the virus would activate sooner than expected and that there would be no time to destroy the virus, which she has yet to finish writing.

She later arrives in the spot where Amai Ao took Last Order, calls the ambulances, and later shoots Amai Ao, but is unable to shoot him in vital spots.

He also tells her that Accelerator has lost his calculation abilities, basically making him cripple, but said to her that he will make use of the Misaka network to compensate for what he has lost, using them for his calculations. He tells her that she was saved easily, because Accelerator used his powers, despite being unconscious, to keep blood from spilling from her after getting shot Amai Ao. Before leaving Heaven Canceller tells her that she has been fired, as the Level 6 Shift, due to heir little display with Amai Ao, has been permanently closed, and that she should choose another path that is not that of a researcher, amongst the many paths. Kikyou says that she will not forgive the Heaven Canceller if he fails to save Accelerator, and he reminds her who he is, before leaving to operate on him. Here, she is proud that Accelerator was able to save instead of destroy.
