Will Kakashi get his sharingan back in Boruto?

No. During the fight with Kaguya, Obito had both of his sharingan which he lent Kakashi after his death. After this fight we see both the Sharingan is Kakashi’s eyes fade, never to return again.

Why did Kakashi’s sharingan disappear?

If you want the non-satirical answer, he lost it because Obito’s chakra dissipated. Obito, who has a bit of 6P chakra, gave Kakashi the chakra he had and allowed Kakashi to use both the Kamui Mangekyou. Obito’s chakra doesn’t last forever, and Kakashi “loses” the Sharingan after Obito’s chakra dissipates.

What is Kakashi’s new sharingan?

Kakashi awakened the Mangekyo Sharingan when Rin was killed. He thus failed to keep his promise to Obito. Hence, this was a emotionally painful moment for him, tied to both Rin and Obito.

Is Kakashi’s sharingan always on?

His sharingan was always ON yes but the reason he covered it was because he didn’t want his enemies to know about this ability of his. If people knew that there was a non-uchiha sharingan user then they would try to steal it as it is easier to steal it from a non-uchiha.

Why did Kakashi lose his Sharingan but not danzo?

This was the doing of the spirit of Obito and not the physical self. Hence the Sharingan Kakashi used was spiritually influenced. Later, when Kaguya is defeated, Obito’s spirit leaves Kakashi’s side to join the other world. Because of the spirit leaving, the Sharingan also disappears along with it.

What is wrong with Kakashi’s eye?

His Sharingan was stolen by Madara. Though right after Obito died, he entered Kakashi’s psyche and temporarily gave him his powers. Kakashi lost that power for good after Kaguya was beaten. The eyes themselves crumbled to ash, just like the rest of Obito’s body.

Can Kakashi still use Chidori?

In fact, Kakashi’s Chidori is a failed attempt at adding his lightning nature to the Rasengan. After losing the Sharingan, he still has access to this jutsu today.
