A/N: So I'm a huge KakaRin fan, I don't hate Obito, I just think Kakashi deserves hapiness after all he's been through. It makes sense to me at least. I've looked and there aren't many KakaRin stories so I thought I would contribute.

Disclaimer: I don't own Naruto, if I did KakaRin would have happened

Rin was scared, after her failed attempt at one of the forbidden jutsu she just didn't know what to do. She didn't know what came over her. After seeing Obito's team and the similarities to her old team she just had to try to bring Kakashi back.

He had died protecting her after the three-tails was sealed inside of her. She begged him not to, but Kakashi had made a promise, a promise to Obito. His lightning blade cut through most of the enemy ninja, but there were too many. When they cut Kakashi down a dark figure appeared and killed the remaining ninja, the figure turned out to be Obito. Crushed by Kakashi's death, Rin was never really the same, just like when they thought Obito died.

Eventually they moved on. Obito was back and Anko was overjoyed, but Rin, she started to toughen up, getting stronger while also improving her medical ninjutsu. Obito always heard her when they visited Kakashi's grave with Minato-Sensei, "If only I was stronger, I could have saved him".

Eventually Obito and Minato got her to open up again. She quickly became attached to the genin on Obito's team. One day though, after one of his many dates with Anko, Obito went to find Rin and tell her about how things were going. He knew something was wrong after his team told him that she broke down earlier in the day. He didn't find her at Kakashi's grave which was the only place he thought she would go.

When he found her with the scroll of forbidden Jutsu earlier in the Chunin exams he knew exactly what she was trying to do. Her tears were enough for him to realize it didn't work. Obito finally got through to her again. He realized that his team's antics caused her breakdown. He did the only thing he could think of, "Kakashi will always be the greatest shinobi in my eyes not because of his genius or his strength, but because he kept his promise when I would have been too late."

Rin cried even after Minato-Sensei arrived. "Come on, Rin, Obito, we should go talk to him," Minato suggested.

They walked in silence to the grave. Rin fell to her knees before the grave and started crying again. "She's been ok for years now, what broke her to make her go this far?" Minato asked Obito.

"It was my team, unfortunately, they are very similar to the old team 7," Obito began, "Apparently one of the sound ninja approached her, said something to her, and she collapsed on the spot". Obito was starting to get angry, which wasn't a good sign for the remainder of team Minato. One of his former student in tears the other ready to hurt the shinobi that hurt her.

Just like old times, Minato thought to himself. It pained him to know that something from the old days would never come back. Tomorrow was the last part of the Chunin exams, he needed his team at full strength.

"Rin," the kunoichi looked up to her former sensei from her spot on the ground, "He wouldn't want you to worry about him this much, we have a big day tomorrow and Kakashi would want you to be ready for it".

"Yes Minato-Sensei," she replied with tears still falling. With that they returned to prepare for the Chunin exams.

Rin didn't know what to do. The Chunin exams were happening and then the sand ninja that had been fighting Sasuke transformed into the Shukaku. Orochimaru had appeared and started fighting the fourth and third Hokages. They were trapped in a barrier and Rin and Obito couldn't do anything about it. The monstrous Shukaku was trampling everything in its path.

"Rin!" Obito shouted over the commotion going on in the village, "You have to use the power of the three-tails! It's the only way to fight it."

"You know I can't control it Obito, there's no way that I could do it without hurting more people," Rin pleaded.

"Kushina isn't here so we can't use the power of the nine-tails, it's the only way," Obito told her. He was completely serious, he saw no other way out.

Suddenly a giant toad appeared to fight the beast. It was Naruto, though, they weren't really too surprised. The battle was epic, but in the end Naruto hit the boy to wake him and defeat Shukaku. It worked as the Shukaku slowly started to fall apart.

Seemingly out of nowhere a genjutsu was activated putting the boy immediately back to sleep. Shukaku started reforming knocking the giant toad away. Naruto was out of strength and collapsed, the toad stayed to defend the boy.

"Rin, it's our only option." Obito repeated.

"Fine, but if I lose control," Rin paused to take a deep breath, "I want you to stop me by any means, promise me?"

It took Obito a minute before he answered with a slow and sorrowful, "I promise."

As Rin started to weave the hand signs that Minato had shown her to release the three-tails chakra, she turned to Obito, "One more thing, just tie the knot with Anko, you've waited long enough already." Obito started to turn a little red at Rin's remark before returning to his previous serious demeanor, ready to attack the remaining enemies head on with his one sharingan.

Before either of them could finish what they were doing something akin to a lightning bolt shot up from the ground in front of Shukaku. When the light faded everyone was just as stunned as when Shukaku appeared. In the lightning's place was a giant man made of lightning and fire. It had wings and wore battle garb. Instead of a face the thing had a mask with a slash going over its left eye. The being drew one of its swords and charged at Shukaku. The sword sliced off Shukaku's left arm entirely, but the sand started to quickly reform. Without missing a beat the being kept up its attack hacking and slashing with its sword, chopping off piece after piece of Shukaku but not fast enough to stop it from reforming.

The Shukaku then launched its assault, but the lightning being dodged and blocked every strike. In one quick slash, the devastating counter attack from the being cut off the beast's arm and suddenly reality warped, swirling inward, and the arm completely disappeared. Shukaku roared, firing air bullets at the lightning giant. The giant easily cut through all of them.

The giant stuck out its right hand and an unforgettable sound cut through the air as chakra flared around the giant's right hand. The sound of thousands of birds chirping ripped through the ears of everyone in the village. With blinding speed the giant's hand shot through the beasts head. The form of the Shukaku slowly melted away from around the giant's arm.

The giant crouched down and swiped its hand to the spot behind the toad and through the forest. Opening its wings the being flew back to the arena in the village where Rin and Obito were. It landed and gently released from its grasp Naruto, Sakura, and the sand ninja, including the boy that became the Shukaku, onto the ground.

Obito was impressed that after the whole fight that the giant had managed not to kill its opponent even if it was a beast with near unstoppable power. Rin looked up at the blue lightning giant in amazement. They both tensed as the giant turned its red glowing eyes on them.

Guy, Kurenai, Anko, and Asuma had appeared in the arena as well and only stared up at the towering giant. They were prepared for the worst, even though they were almost positive that even with all of them they probably couldn't bring the giant down. A kunai shot down implanting itself in the ground between the Jonin. In a flash Minato teleported down from where his fight with Orochimaru had taken place. Holding his kunai at the ready he stared down the giant, but unlike the others there his gaze held a confidence and a resolve that only a Hokage could have.

"This is a sad day for the Hidden Leaf, but it's still not over," Minato spoke to the Jonin behind him, "When I give the signal Asuma and Kurenai will attack its legs, Guy will try to stop it from drawing its sword, Obito, Anko, go for its arms, try to keep it on the defensive, Rin try to keep it away from the village and the genin over there and heal anyone here when possible, I will go for the strange glow in its forehead."

"Right," they all answered.

Before they could do anything the being started to dissipate into thin air, slowly fading into nothing. What remained was a man wearing a Jonin uniform. He had a headband with the symbol of the Hidden Leaf on it, and he wore a mask that covered his nose and mouth. He had a scar over his left eye and his silver, spiky hair blowed in the wind.

The man opened his eyes revealing two sharingan staring at them. Everyone in the group tensed at the sight of him. His red eyes switched between all of them before landing on Obito, Minato, and Rin. Upon seeing them the man took a menacing step forward. Everyone was ready to attack with the slightest movement from the strange shinobi.

"Why?" the man growled. His sharingan swirled and took a strange shape as reality warped again and a kunai that Minato threw at the man disappeared into nothingness, startling all of them, even if they didn't show it. Blood started to fall from his eyes, almost forming tears, showing the strain that the man had put on his body. "Why? Minato, Obito, Rin," the words were low, filled with sadness and rage at the same time, as the shinobi took an offensive stance.

Before anyone could ask how the mysterious shinobi knew them, he collapsed to the ground, unconscious. "So," Obito began, the first one to break free of his astonishment, "What should we do with him, Minato-Sensei?"

"He did save the village," the Hokage reasoned, "take him to the hospital, once he wakes up we'll get to the bottom of this, until then I don't want anyone saying a word of this to anyone outside of this group without my permission," he ordered. "We will reconvene once he wakes up, dismissed."

With that the shinobi parted to help with the clean-up of the village, taking out the last of the sound and sand ninja. Minato picked up Naruto to take him home while ordering other shinobi to notify Sakura's parents about what happened and remove the sand genin from the arena.

As she was running through the village taking down enemy shinobi and healing any wounded she found, Rin had a though nagging at the back of her mind: the shinobi who saved the village reminded her of someone.

A/N: Remember, constructive criticism is appreciated and hate will be ignored.

Also I have six other chapters pre-written and I am not short on ideas for where to take the story, but don't worry, I'm still trying to improve my writing so I will be listening to my readers.
