Naruto: I'm Nine-Tails and My Host is Kushina

Obito was stunned.

This Kurama actually appeared inside his Kamui dimension.

"How the hell did you get in here?"

Kurama smiled faintly, eyes glowing with amusement.

Did he need to explain anything to Obito? Absolutely not. Some things are better left unsaid.

It was time to end everything.

In an instant, a dark red chakra tendril shot out from Kurama and wrapped around Obito’s entire body.

Without his intangibility active, Obito was just another shinobi—vulnerable.

"My dear disciple," Kurama said mockingly, "you seem awfully attached to that eyeball."

Obito’s Sharingan flared with rage. His bloodshot eyes widened.

"You bastard... You took everything from me. Rin... Rin can never be replaced in my heart!"

He roared, trembling with fury.
