Naruto: Uchiha Survivor Forced to Save the Shinobi World

Uchiha Shinji quickly snapped back to his senses and, using "Jikibi," spoke to both Yakumo and Ido simultaneously. "Don't panic—you just successfully activated that dojutsu!"

"We did?"

Yakumo and Ido exclaimed in unison, startled.

After briefly organizing his thoughts, Uchiha Shinji grasped the situation and explained, "The mysterious dojutsu hidden within Koryugan is likely a space-time ninjutsu!"

"S-Space-time ninjutsu?!"

Yakumo and Ido both looked bewildered.

Clearly.

A technique of the caliber of "space-time ninjutsu" was, for academy students like them, a bit too complex and advanced.

"That's right, a space-time ninjutsu!" Pausing for a moment, Uchiha Shinji continued, "My initial deduction is that this technique's ability is to swap your positions."

Ido immediately chimed in, "No wonder I suddenly ended up back in the village."

Yakumo finally understood. The spot she was standing in now was exactly where Ido had been seconds ago. Because the dojutsu had swapped their locations, she'd gone from the village to here in an instant.
