The Closed Box Theory
Inside the Hokage's building there is a room. This room contains boxes. One box for every ninja in the village, a place for them to store their most loved possessions safe from harm. Only the ninja in question has the ability to open their box and unless they leave instructions for what the village is to do with the box after their death, it is destroyed without ever being opened. The exception to this rule is missing nins, where the Hokage forces the box open to inspect the contents.
The box was twenty centimetres length and breadth and ten in depth. The only difference was the Hokage's, which is an entire room. The Yondaime's room has been sealed and his last will and testament states that it should be left to the next Namikaze to become Hokage.
This is a tour through the stories behind some of the items in some characters boxes.
What's in Sakura's box?
Sakura's box shows how deluded she is, not because the box is full of objects, but because it is empty.
Sakura kept the box for when she received a gift from Sasuke. And to this day she keeps the box ready for the gift that will never come. While in her head she thinks she has grown up, she still lusts over what she cannot have.
What's in Ino's box?
There is only one object in Ino's box. One that she will never be able to remove.
A pregnancy test. A used, positive, pregnancy test. It was from Ino's first and only baby. Two years after Naruto left for training she became pregnant after a mission. The Farther had been a pointless villager; she had picked him up as a lover to help her get over a particularly difficult mission, someone she could empty her feelings into before taking him to bed. However due to a heavy amount of drinking she forgot to use the usual contraceptives.
After a few bouts of morning sickness she decided to get the test kit. To say she was shocked was an understatement, she went directly to an aunt who was a retired med-nin for a second opinion, she passed out upon hearing the conformation. There were rules against pregnant kunoichi taking missions, however Ino convinced her aunt to keep quiet about the pregnancy while she used B-class missions to raise the money to move out of her parents.
It was on the fifth mission when she lost her baby. Seven weeks into the pregnancy on a solo recon mission she was ambushed by a trio of Chuunin missing-nin . As her mission was a one-man infiltration she had no one to watch her body, this meant that nearly none of her family techniques would work.
The fight was short and brutal. At the end one of her opponents lay dead and another was severely burnt. The last took it upon himself to make his teams displeasure known. Ino was
raped multiple times the man, the damage was done however not by the rape but by the beatings afterwards. The torture lasted for several days before purely by blind luck a Chuunin from wind on an almost identical infiltration mission caught the smell of blood on the breeze. Following it he happened upon the small camp that the two ninja had set up and the broken and bloody body of Ino. The unidentified ninja slaughtered the missing-nin while they slept. Instead of continuing with his mission he carried the near dead ninja to her countries boarder, he left her in the arms of a very shocked Team Ebisu who had been assigned light border patrol. When she finaly made it back to Konoha's hospital she was given the bad news from Sakura. In all her injuries included three ribs that had to be removed (as the damage was so extream that even Tsunade knew they were beyond repair), a liver transplant, steel pins in both arms and a plate in her hip. But these paled into nothing compared with the last one, a slow bleed had occurred inside the wall of her womb causing her to miscarry, but in order to stop the bleed the Slug Sannin herself had been forced to perform a Hysterectomy.
Ino broke inside, rather than greave for her loss she imidiatly threw herself back into ninja life by apprenticing herself to the torture expert Morino Ibiki. By the time naruto returned her scars had healed to the point they were near invisible. But every Saturday she spends an hour staring blankly at the test before putting it away and going out to face the world.
