Why Did Kakashi Lose His Sharingan? Does He Ever Get It Back?

After perishing a second time, Obito does exactly what he did during his first death. He lent Kakashi some of his strength and granted him temporary access to the Mangekyō Sharingan in both of his eyes. With his new powers, he works together with Naruto, Sasuke, and Sakura Haruno to defeat Kaguya and save the world. But as Obito’s spirit passes on, Kakashi’s Sharingan disappears with him.
