Konan

Origin

One of the three orphans, Yahiko, went up to the travelling Sannin and asked for food, which Jiraiya gave him. Yahiko then told Konan and Nagato that they're friendly and the three started following the Sannin, wanting to be taught ninjutsu. Konan used the food wrapper to make Jiraiya a paper flower with origami. Tsunade got annoyed with them and wanted them to go away, Orochimaru on the other hand thought the most merciful thing they could do was to kill them since their lives are going to be so hard, being helpless orphans during a war. Jiraiya became angered and told Tsunade and Orochimaru to go on ahead with out him and decided to stay and train the three orphans. When Nagato and Yahiko were attacked by a Rock ninja, Konan brought Jiraiya to help. After three years of training under Jiraiya, Konan, Yahiko, and Nagato were able to defeat one of Jiraiya's Shadow Clones, at which point Jiraiya felt that they were ready to protect themselves... and asked Konan to come see him when she's older.

In the present, when Pein detected an intruder, someone dangerous, Konan went to scout. When they found out the intruder was Jiraiya, Pein told her that he didn't love Jiraiya anymore and that they'll kill him. Konan went ahead of Pein and attacked Jiraiya who retaliated with a Fireball. Much of her paper was burned, but she was able to avoid it. Jiraiya started questioning her, but she just kept attacking. Jiraiya spewed Toad Oil all over her, causing her paper to stick together, then trapped her with his hair. Jiraiya tried to question her again but she was angry at him for leaving them. Jiraiya told her that he heard rumors about them after he left and later hearing that they were killed, Konan told him that he has no idea what happened to them after he left. Pein then showed up and freed Konan, then told her to leave.
