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.

Personality
Konan has a relatively mysterious personality, mostly she is stoic, calm, and level-headed(much like Pein). As a child she was bright and relitively cheerful compared to the tough Yahiko and sensitive Nagato, however the truma's of events since then have left her more serious and solemn and she never spoke until her most recent appearances. She does seem to be more empathic than other Akatsuki, as she appears sad whenever she has been reminded of her past. She also exresses a great deal of loyalty and courtesy to Pein, doing his bidding without question and looking out for his well being. She seems to act as an intermediary between Pein and Amegakure, the villages having given her the title "God's Angel" for this reason. Her courtesy is always returned by Pein, and he freed her from Jiraiya's grasp without hesitation or request.

Abilities
Konan is a shinobi of some power, as she is held in high regard by her partner Pein. However Jiraiya held her off with relative ease. She has a natural talent for origami, as seen with the paper flower she keeps in her hair. As a child, after training with Jiraiya she was able to form paper weapons infused with her chakra which could pierce flesh easily.

As an adult and member of Akatsuki her powers have grown considerably. Her entire body now appears to be composed of thousands of sheets of paper with she can control at will and form into any shape. To travel long distances she can mold then into butterflies or planes for powered flight, and to attack the can form arrows, shuriken, or spears. She can also restrain opponents by blanketing them in sheets restricting their movement. Befitting (and likely inspiring) her title as 'Gods Angel' the papers can also form large wings for flight or further weaponry. As a whole she is probably quite difficult to harm since most physical attacks would go straight through her, but this has yet to be confirmed.

She does have weaknesses though, primarily water, since paper clings to itself and looses stiffness when wet. To negate this, pein has to stop the rain for her whenever she moves around the village. Jiraiya easily negated her abilities by smothering her in oil. Further she appears vulnerable to fire based techniques.

Part in the Story
Konan appears when she tells Pein that Madara Uchiha has arrived. When it starts raining after Madara leaves, she comments on how the rain makes it seem that the village is crying. She later appears when Jiraiya infiltrates Amegakure, entering the rain shower and becoming detected by Pein. When Pein stops the rain, Konan uses her abilities to find Jiraiya while Pein changing bodies. She returns to inform Pein that it's Jiraiya, and goes to hold him off for Pein. She attacks Jiraiya with paper spears, but he sees it coming and uses his Toad Fire Technique to stop the spears. Jiraiya remembers her, complimenting her on her power and beauty. She fights Jiraiya on equal footing until Pein arrives, and leaves when they get serious. She regroups with him once he finishes Jiraiya.
