After about half a year of living together, everyone had become tentative friends. After one year, Tsunade and Shizune joined them, basically disappearing off the map with them. All of the jinjuriki regarded them with caution at first, but eventually everyone let their guards down and came to trust the two. Since before being kidnapped Yugito, Yagura, Roshi, Han, Utakata, and Killer B had already begun their ninja training Jiraiya decided to continue their training, teaching them as much as he could. After Tsunade and Shizune arrived, they took over some of the training too, teaching them about pressure points and basic first aid. After about six months of training under all three of them, Jiraiya had a pretty good idea of their strength. He set up a system of special kunai with the Flying Thunder God space-time jutsu formula that Minato favored. He gave them to the leaders of all of the countries that didn't have a ninja village, telling each leader to drop some blood on it if they ever needed ninja to for emergencies. The adults would flash there and check to make sure that there weren't any ninja from the jinjuriki's home villages nearby and Han, Roshi, Yagura, and Killer B took turns forming a team and taking care of such missions under the supervision of one of the tree adults. The others were told that they would be allowed to go on mission as well when they were 10.

Naruto(with Kurama's help)realized that Fuu and Gaara had some 'giant animal' in them too so they would sit down together and under Kurama's guidance (instructions told to them by Naruto) learned to meditate and communicate with their 'giant animals' they all became good friends with their 'giant animals' and because their names were hard for two and four year-olds to pronounce, they were promptly nicknamed Shu-kun and Mei-chan.(With the biju'ssomewhat reluctant agreement of course. The six became close enough to be family and eventually opened a mind link- credit to the biju. The three children soon learned to keep a straight face o continue to act normal regardless of the circumstances as is befitting a ninja. This was so that they wouldn't suddenly burst out laughing when one of them said something funny. As it was, they were getting together great and having lots of fun as the others trained and went on missions.

After about two years, Jiraiya realized that all three of them were on speaking terms with their biju and asked how. After that, all the jijuriki learned to meditate and got on proper speaking terms with their biju.

When Gaara and Naruto turned five, Jiraiya started to train them to become ninja as well. Since Fuu was the only one that hadn't started train Shizune trained with her for chakra control and had her help with the chores includin cooking, cleaning, and doing the laundry. The older kids helped out when they weren't training of course.

When Fuu turned five she began formal training as well.

Whenever one of the Jinjuriki turned eight, Jiraiya told them the truth about the biju.

They soon came to regard each other as family. For his ninth birthday, Kurama told Naruto a secret, all of the tailed beasts gives their users special abilities. With this revelation, all of the jinjuriki started to train with their biju to master these abilities.
