Background

After betraying Orochimaru, Sasuke travelled to various Otogakure bases to recruit his three team-mates, Suigetsu Hōzuki, Karin, and Jūgo. After witnessing Itachi's death, and learning Konoha's role in the Uchiha clan massacre from Tobi, Sasuke renamed the team "Taka" with the new goal to crush Konoha.

Although their team was originally one of necessity, they all came to respect each other as team-mates and even risked their lives to protect one another as time went on, reminding Sasuke ofTeam 7. However, as Sasuke became more corrupt and focused in his revenge against Konoha, he abandoned Jūgo and Suigetsu in the Land of Ironto pursue Danzō, and, when Karin became a burden to him, he critically wounded her, and also tried to kill her to avoid any trouble with her — but she was saved by Sakura and Kakashi, and taken back to Konoha. Currently, while Karin states that she was finished with Sasuke and tries to escape from the Konoha prison, Jūgo and Suigetsu, not knowing what Sasuke did and tried to do to Karin, reunited with Sasuke and have since continued to assist him. They were later met with Karin in Konoha, and she decided to rejoin them regardless of everything that happened in the past.
