Konan

is the only female ninja in Akatsuki and the only member to call her partner, Pein, by his name.

Background
When she was younger, Konan, Nagato, and Yahiko were left orphaned by one of Amegakure's many wars, forcing them to fend for themselves. The three eventually encountered the Sannin, who gave them some food. Konan impressed them by making an elaborate flower out of the paper wrappers left behind. After Nagato killed the Rock Chunin, Jiraiya took them up on their offer and began to teach them ninjutsu. Jiraiya believed Konan to have died with Nagato and Yahiko some time later, and upon seeing her again years later he comments on how beautiful she has become.

Akatsuki's Goal
Similar to Pein, Konan has spent the most of their mission at the Akatsuki base in Amegakure. There she has been known as "Pein's Angel" by doing Pein's bidding. When Jiraiya infiltrated the village, Pein stopped the rain for Konan to find and kill him. Although she found him, Jiraiya quickly covered her in oil leaving her defenseless until Pein arrived.

Abilities
Konan has a natural talent for origami, as seen with the paper flower she keeps in her hair. This talent extends to her type of jutsu, as she can divide her body into countless numbers of paper sheets. These sheets can be controlled individually and formed into various shapes for a number of purposes; butterflies for scouting, spears for attack, or darts with which to pummel opponents. Konan can even form wings from that allow her to fly. This has led to her title as "Pein's Angel", a reference to her wings, and the fact that she "serves Pein". Like all paper, Konan is unable to use her abilities while wet.
