I decided to give a try out at a Naruto x One Piece story. Yes, I know this is pretty much not a big deal right now, but I can imagine when Naruto was still being published this was a big deal and people still come up with lots of theories and ideas for crossovers. So, I decided to give this a shot, this take place after the battle of the Three Sages, so Tsunade is Hokage and Sasuke hasn't run out yet. So, let's start.
At Tsunade office.
The new hokage was trying to get used to the piles and piles of paper that are in her office, trying to be calm while running the hidden village of the leaf is not an easy task, but Tsunade would do what she can.
''Lady Tsunade.'' Said her secretary Shizune soon appearing.
''Hey Shizune, thank God you are here. I was so bored that I was gonna buried myself with all this paper.'' Said Tsunade.
''We need to talk about something.'' Said Shizune.
''What is it?" Asked Tsunade.
''So, I was looking at the files and it seems that this office has a lot of missions that weren't taken.'' Said Shizune.
''In other words, the reason that there is too many documents here is because some ninjas didn't take their quest?'' Asked Tsunade.
''Well, that might be case. I was looking down and found a box full of old missions that were never taken.'' Said Shizune.
The secretary soon show up a huge box, probably filled with tons of paper. Tsunade worst nightmare.
''I guess we need to check it out.'' Said Shizune.
''Let just end this nightmare at once.'' Said Tsunase.
Shizune soon opened the box and saw thousands of mission there.
''Wow, how old are those missions?'' Asked Shizune.
''I guess the old man never bothered to clean this up.'' Said Tsunade thinking of her sensei.
''No way that Lord Third would do such a thing!'' Said Shizune.
Tsunade soon started to look at the mission and giving her opinions.
''Garbage! Garbage! Burn! Buried! Throw out.'' Said her not liking in what she was seeing.
''Why some of these missions are so…. unfit?'' Asked Shizune all red while she reads the requirements for one mission.
''Is from before you were born, things were different.'' Said Tsunade.
The Hokage tried to find at least one mission that could still be worthy the time of the current generation and behold she found one.
''Oh, this one seen perfect and is still on the valid date!'' Said her all happy.
´´Ancient Artifact Missing. Need huge party to find it.´´
''I think is perfect. The kids really need this.'' Said Tsunade.
''i don't think is a good idea.'' Said Shizune reading the warnings.
''Please, they can handle after everything that just happen in the last few months. Now call their sensei's, we need to discuss this.'' Said her.
''Sure.'' Said Shizune leaving.
Tsunade soon was ready at the mission and wondering why this wasn't finished before. The reason unknown to her is that every ninja that tried disappeared from the face of the Earth.
