"I can't believe I actually forgot about the nine tails!" Ren thought. "I was too focused on my training to pay attention to anything else, damn!"
"Ren we need to go to the shelter!" Itachi exclaims while he starts moving with Sasuke in his arms.
...
As Ren and Itachi were running towards the shelter, they could hear the sounds of despair and destruction throughout the village. Dust clouds started piling up from all the destroyed houses being turned into rubble.
"Ren watch out! Itachi screamed as a block of rubble was falling down on Ren.
Ren, however, was able to react in time and jumped back narrowly dodging the rubble. But, now they were separated from each other as the rubble blocked the alleyway they were in.
"Ren! Are you okay?!" Itachi worriedly asked.
"I'm fine Itachi" Ren replied, then continued "You go on ahead!".
"But Re-"
"I'll catch up in a bit!" Ren said as he interrupted Itachi.
"Okay, but be careful" Itachi worriedly responded as he started leaving.
...
As Ren was running towards the bunker there were huge dust clouds formed by the countless amount of destroyed rubble.Even though the dust clouds were obscuring his field of vision of the once lively and happy Konohagakure, he could tell there was no resemblance of Konohagakure and this place filled with corpses and destroyed buildings.
As he ran through the streets he hears crying in an alleyway, suddenly stopping he sees a girl around the same age as her eyes closed and hands covering her face.
"Hey! get away from there!" Ren yelled.
But what shocked Ren was when she looked up at him she had red eyes. She had the one tomoe Sharingan.
"Someone around my age who unlocked the Sharingan, something must have happened to her."
"Dad is dead," she said as she continued to weep.
However, there was a blast of rubble coming towards the little girl. Before Ren could even feel bad for this little girl he instantly moved towards the girl, grabbing her and pulling her out of the way of the incoming rubble. (Image the Itachi scene where he finds Izumi and pulls her out of the way)
"I'm sorry for your lost, but we need to get moving otherwise we will both die too," Ren whispered to the girl as he started pulling her along before she could even respond.
As they were moving Ren hears a silent "Thank you" from behind.
...
"Itachi, I knew you'd be alright." Fugaku says as he sees Itachi but then continues "where's Ren?".
"Father, Itachi and I got separated as we were running towards the shelter"
"En, go ahead to the shelter I'll keep watch."
"Ren, you better be okay." Itachi quietly mumbles.
...
"We finally made it to the shelter," Ren says exhaustedly.
"Um, I'm Izumi Uchiha thank you for saving me," Izumi said while wiping the tears coming from her eyes which reverted back from the Sharingan.
"No problem, as a future ninja it's my job to help anyone I see, my name is Ren Uchiha."
Hearing her name Ren was actually quite shocked, according to his memories Izumi was infatuated with Itachi and awoke her Mangekyo Sharingan during the night the entire Uchiha clan was slaughtered, besides for Sasuke of course.
