Konan

Konan was a female from Hidden Village Of Rain and the only female  member of Akatsuki. She was partnered with Nagato. After Nagato's death, she defected from the organisation and became the leader of Hidden Village of Rain before her own death.
At younger age, Konan's family was killed during the Second Shinobi World War, and she was left to fend for herself.Some time later, She was found by Yahiko, and the two worked hard to survive. After some days, Konan went for a walk and found a young, dying boy and his dog. She rescued him and brought him back to their place. Gradually the three became best friends. They encountered the Sannin of Konoha, who gave them some food. Konan impressed them by making  flower out of the paper wrappers left behind as a sign of gratitude. When Orochimaru suggested to kill them, Jiraiya said that he'll be there with these childern and he'll train them so that they can survive


After Jiraiya taught them Ninja techniques and was confident they could take care of themselves, he left them there. Before leaving, He tells Konan that she will be very beautiful when she grows up and to come and see him when she reaches her adulthood. During their time with Jiraiya, he made a defence system, composed of four planks, each with one red side and one white (the white side also had a frog picture on it), attached to a part of a wall of the hideout they shared at the time with a string and a nail, each one above one of their names, which he called "Hop-In" planks. Nagato's, Yahiko's and Konan's were one wall and Jiraiya's was on a wall opposite. The purpose of the planks were that when they were in the hideout, they turn their planks to the red side and when they leave, they flip their plank to the white side, so when a plank's on the red side and the person's not in the hideout, it means they could have been captured by the enemy and when a plank's on the white side and it appears that the person's in the hideout, it could mean that an enemy has transformed into said person and has infiltrated the hideout.
 Over the time,those three formed the Akatsuki and became renowned for their strength, with news of their actions even reaching Jiraiya sama. When their group became too big, they changed their hideout, and left their current one where they once lived with Jiraiya. When they were about to leave and flip over their "Hop-In" planks, a ninja squad attacked the hideout creating an explosion. Yahiko (after Konan flipped her plank and just before he was about to flip his), noticed the attack in time and used the escape route just before ninja entered the hideout. After that Konan fell in Love with Yahiko.

They met Obito Uchiha at Orphans Hideout, where he claimed that he is Uchiha Madara and searching for peace , which can be brought by Eyes that Nagato had.
Hanzo, the then leader of Hidden village of rain, feared that Akatsuki would overthrow him. As such, he and Danzo of Konoha  deceived the group into meeting with them about an allegiance for peace. When Nagato and Yahiko went to meet with them, they kidnapped Konan and ordered Nagato to kill Yahiko in exchange for her life. Konan cried out for them to flee without her, but they refused to leave her behind. Although Nagato was paralysed in shock by the order, Yahiko stabbed himself with the kunai in Nagato's hand.  Nagato saved Konan afterwards, who would thereafter accompany him wherever he went.
