- Why did Rin sacrifice herself?
- Why did Rin jump in front of Kakashi’s Chidori?
- Why did the mist want Rin?
She was forcibly made into the jinchūriki of the Three Tails Isobu, as an elaborate scheme by Kirigakure to destroy her village. Rin, however, would ultimately sacrifice herself to ensure the safety of the people she loved.
Rin jumped in front of Kakashi’s chidori because the hidden mist made her a jinchuuriki of the three tails Isobu, fearing that she wouldn’t be able to contain the three tails and it going on a rampage through the hidden leaf like the mist wanted.
When they were on a mission in the Hidden Mist, the Hidden Mist ninja captured Rin and made her into the 3 tails’ Jinchuuriki. Their purpose was for Rin to return to the village, where they’ll undo the seal, kill Rin and have the 3 tails rampage on the Hidden Leaf.
