Kakashi killed Rin in episode 371 of Naruto Shippuden anime. He unintentionally killed her in order to prevent the unleashing of the three-tailed beast known as Isobu, which their enemies had sealed in her. Had that wild beast been unleashed in the village of Konoha, it would have killed several of the villagers.
This situation made Kakashi agonize over killing Rin as she was a good person as well as his friend and teammate. She, however, took the decision out of his hand by jumping into the path of his powerful lightning blade, thus basically committing suicide for the greater good of her village.
The History of Kakashi and Rin
The history of Kakashi and Rin is fully explored in the Naruto spin-off known as Kakashi Gaiden. While Kakashi makes it into Naruto part 1, Naruto part II and Boruto: Naruto Next Generations, Rin is already long dead before then. As such, the place where her backstory and that of Kakashi are fully explored is the spin-off, Kakashi Gaiden.
Kakashi and Rin are both age mates born in the village of Konoha. Rin is also best friends with another of their peers known as Obito Uchiha. Just like other kids, Kakashi, Rin, and Obito make it into the ninja academy at an early age. Upon their graduation, all three are placed under the tutelage of Minato Namikaze. They perform various tasks and eventually pass their Chūnin Exams. Upon passing these exams, Kakashi, Rin, and Obito, alongside their teacher, embark on various missions to defend their village of Konoha. They also take part in the third shinobi war.
During this war, the team is tasked with destroying the Kannabi Bridge, which serves as a vital pathway of supply for one of Konoha’s enemies. They bravely embark on this mission, but Rin is kidnapped by the enemies. Her enemies try to use their powers to get her to spill secret information about Konoha’s war strategy, but she successfully resists them until Kakashi and Obito rescue her. Unfortunately, Obito is crushed in a cave-in during the rescue. However, before his death, he gifts his powerful Sharingan eyes to Kakashi.
What Episode Does Kakashi Kill Rin?
Kakashi killed Rin in episode 371 of Naruto Shippuden anime. It must, however, be pointed out that the killing actually took place numerous episodes before this particular episode. It is, however, only in a flashback in episode 371 that we actually see what transpired. Following the death of Obito, Kakashi, and Rin, together with their tutor, Minato, complete the mission of destroying the Kannabi Bridge.
They continue with their other activities until Rin is once more kidnapped by enemies from Kirigakure or the hidden mist village. Kakashi rescues her once more, but on their way back to their village of Konoha, she jumps in front of his powerful lightning blade. This lightning blade is his hand-controlled lighting chakra, and it pierces her chest and kills her on the spot.
