Rin sees the enemy's bushy head appear in the hold Kakashi had previously made in the rubble. "Don't panic," Obito tells his frightened love. Kakashi's head replaces the enemy's head not long after. Rin releases the breath she had been unknowingly holding in. "Kakashi, take Rin, find Yuuki, and go. Reinforcements…coming…"
"Obito…" Rin clutches Obito's hand tighter than she had already been.
"It's okay! Just go…" Obito tells the girl, pulling his hand from hers reluctantly.
"Rin…" Kakashi pleads with the girl, reaching his hand inside the small man-made cave. She looks back and forth between the boy she loved and the boy who loved her. A plethora of enemy reinforcements appear behind Kakashi, all simultaneously performing an earthquake jutsu. As the small cave collapses around Rin and Obito, Kakashi snatches Rin's hand and pulls the small girl from the makeshift cave. The rubble collapses completely on Obito's body as Kakashi brings the sobbing Rin high into a tree.

Feeling the tremors of the earthquake jutsu, and feeling the multitude of foreign chakras, and lack of one very familiar presence, Yuuki decides she is healed well enough. "Obito…no…" Yuuki allows herself a moment to mourn, before standing quickly, deciding that she can mourn later. "Right now, I need to save Rin and Kakashi!" Yuuki motivates herself. Painfully, she takes off into the trees to skirt the huge wasteland of rubble for her two remaining teammates.

Kakashi performs the hand-signs for chidori, realizing that, thanks to Obito's gift, his jutsu was now perfected. His willingness to fight surprises the multitude of enemies surrounding the tired pair. Along with his chidori, Kakashi pulls out the kunai given to him by Minato. "Rin, I'll detain them." When she doesn't respond, he gets more forceful, "go now!"
"But…" she attempts to argue.
"I promised Obito I would protect you with my life!"
"Kakashi!"
"Rin…Obito…he loved you…you were his only one…he gave his life to protect you…" The enemies begin leaping from the trees. "Rin, go!" Kakashi lunges towards the enemies, dropping two small, golden bells from his vest.

Ting-ting. This small sound causes Yuuki to stop in her tracks. "Kashi!" she exclaims frantically. Quickly, she forms the hand signs for a teleportation jutsu and disappears.

Fearlessly, Kakashi fends off enemy after enemy, protecting Rin as best as he can. He hears Rin's voice scream his name before being knocked backwards by an enemy kick. The final blow he expected never came, however. Through his blurry eyes, he sees a mass of purple. Hearing many grunts of pain, Kakashi attempts to reopen his eyes, but he finds himself drifting off. "Kakashi! Kakashi, are you okay?!" He hears a familiar, feminine voice ask him, her voice laced with worry.

A few nights later, in the same small clearing that the group had settled down in to begin with, Kakashi slowly opens his eyes. "Where am I?" he thinks to himself, groggily.
"Hm, you're awake." Kakashi looks over at the masculine voice, realizing that the voice was coming from Minato-sensei. He notices Minato looking worriedly to his right. Before he has a chance to ask whose small body was slumbering next to his sensei, Kakashi hears Minato say, "At least one of you has woken up…"
"Sensei?" Kakashi questions both in confusion as to how he came to be in the clearing and who had yet to wake up. "How?"
"The jutsu formula in this kunai knife sets a mark, allowing me to quickly hop around with my transportation technique," sensei explains, holding up one of his special kunai knives.
"And…the enemy?" Kakashi questions.
"Yuuki dealt with most of them," sensei begins explaining. "I finished them off after she fainted." Kakashi looks over, slightly amazed, at Yuuki's sleeping form.
"Rin!" Kakashi begins, startled, "what about Rin?"
"She's fine. She told me everything while she was healing the worst of your's and Yuuki's wounds." Minato's voice lowers, "I'm sorry I couldn't make it in time."
"Good, Kakashi's awake." Rin says as she walks over to the rock Minato, Kakashi, and Yuuki are currently residing on. "I wish Yuuki would hurry and wake up already…I'm starting to worry…"
"She'll wake up soon…" Minato says quietly, sounding almost like he's trying to comfort himself, as well.
"Yuuki…she heard the bells?" Minato nods at Kakashi. "But how did she fight? Her injuries were so extensive!"
"She healed the most serious of her internal injuries," Rin begins, "I guess when she heard the bells, she thought saving you was more important." Rin lets that sink in for a moment before climbing down from the rock to get some much needed rest.
Kakashi allows a few minutes of silence to pass by before he decides to break it. "Sensei…Obito…" Kakashi pauses, looking down at his lap and searching for the proper words. "He said that Yuuki…that she loved me…is that true?"
"Of course it is!" Minato exclaims, making Kakashi jump a little. "Kakashi, do you really have to ask that after all she's done for you?"
"Sensei, Yuuki will wake up soon," Kakashi says, determination burning in his eyes, "and then…then I'll confess my feelings for her, if you'll allow me to." Minato smiles at the young boy and nods, giving him approval to make his feelings for his daughter known.
The next morning, Minato woke his students, sighing sadly when he was unable to wake up his daughter. The three conscious team members packed their supplies and, after Kakashi picks Yuuki up bridal style, they make their way back to Konoha. From start to finish, the trek was a five day journey, and Yuuki remained unconscious through the entirety of it.
When the worn, tired group reaches the village, Minato takes Yuuki straight to the hospital. The doctors assure the worried father that his daughter will be just fine after she gets plenty of rest as she had overexerted herself during the mission. Despite hearing this news from Minato, Kakashi remains by Yuuki's side. Three days later, however, Kakashi is forced to leave her side as he is ordered to go on a B-rank mission.
Ten days later, Kakashi returns from his mission and rushes to Yuuki's hospital room, only to find it empty. Frantically, Kakashi goes to Yuuki's home, only to be handed a notes a told by Minato that Yuuki had left two days prior to do some training with two well-known shinobi, Jiraiya and Tsunade.
Kakashi returns home sullenly, finds his way to his room, and gingerly opens Yuuki's letter.

'Kakashi
My father told me about how you stayed by my side while I was in the hospital. Thank you so much for worrying about me. I'm sure my father told you that I left to train with two of the great Sanin. I'll be spending exactly five years with them.
Our mission…the death of Obito…they made me realize how useless I was. My training with Tsunade-sama will make me a better medic, so I can be sure that nobody, most importantly you, will ever be injured on my watch again. Not only that, but she'll help me with my courage and strength. And despite Jiraiya-sama's pervertedness, I think he'll be able to teach me a lot of new techniques.
I hope that you'll still be waiting for me when I finally return to the village (yes, my father told me of your feelings). I promise that I'll be stronger when I return.
Please don't die.
With love,
Yuuki'
