This is a KakashixOc story. Just something I started a long time ago and decided to revisit because I enjoyed playing with a different plot!
Prologue!
"Dangerous, extreme, and most likely will cost you your life."
"Don't all missions?" Kakashi said to lighten the mood. It was clear that the distress hokage was on edge and finding this very hard to cope with. It made him all that more nervous as to what the mission was…. Alas, his attempt at making it easier on her only backfired tenfold.
"I didn't call you here to makes jokes, Hatake!"
"Yes...Forgive me."
Tsunade sighed and looked apologetically to him; not meaning to snap. "It's beyond any other mission. In short you will be behind enemy lines and there will be no back up. There won't be anyone to turn to if you get caught. You'll be on your own if you take this."
Kakashi's attention level rose to intense, and no trace of humor remained. It had been a while since he had a mission to this nature, not since Anbu. "How long will this assignment be?"
This was the hard part that she dreaded and, with a firm nod from Jiriaya to continue, that was what she did. "The mission will be until we eliminate the problem and Konoha and Naruto are safe… but your mission won't end there. If-If you survive then you cannot…. Will not return to Konohagakura."
Kakashi's cold stare turned to stone, and he looked to Jiriaya who watched the white-haired ninja questioningly. They let it settle for a moment—letting it sink in. The details were overwhelming, and he could feel the thoughts scramble and fill his mind to the rim.
Eliminate the problem, no return home.
Sounded like a suicide mission.
Too many questions swirled, but only one thought came to mind logically. "Is there another war coming?"
"Eventually," Tsuande answered quietly. "I don't know how far off it is in the future, but it will happen. That's why we need to act now on this."
"I understand."
"…. We can give you the night to think about it," Jiriaya intervened. "But we can't waste too much time on this."
"No," he said firmly, though his instincts screamed that he was rushing his decision. "If I didn't take it then would there be someone else who would? …."
"Yes. We need this to be as successful as possible and you were the first that came to mind." Tsunade leaned forward so her hands were on her desk. "If you have even the slightest of uncertainty or hesitation, I don't want you to feel forced into it. No one will think badly of you if you turn it down. It's your life and your choice."
"I couldn't live with myself if I refused to help Naruto and Konoha because of selfishness; even worse if I knew someone else was going to give up a family to serve."
Taking a deep breath and a small glance to the window looking out to Konoha, he sighed. The sun was drifting lower over the treetops and masquerades of colors painted the skies like an artist's canvas. Such a beautiful sunset during such a depressing report.
"I would be proud to take this mission."
