Obsession For The Fox (Fem!Naruto x ROR!Gods) 18+

Naruko faces Sasuke in a climactic battle but is unable to defeat him. As Sasuke attempts to finish the fight, his attack, intended to kill her, instead opens a rift in space-time due to a miscalculation of his powers, enhanced by the Mangekyō Sharingan and Rinnegan. Naruko is sucked into the portal and transported to a completely different dimension where gods and humans fight in Ragnarok.

The gods, amazed that a mortal was able to go toe-to-toe with them without a divine weapon, become obsessed with claiming her as their own.
