Today was Hiruzen's fifth birthday since he was born . he had no friends and was nervous because this was the first time his parents invited guests to celebrate his birthday .
Nervous because this will be the first time he interacts with other people , Hiruzen started shaking , he went to his room and said to himself ' Hiruzen can you please calm down . Isn't this this what you always wanted , to make friends , just for today lets try our best to make friends ' .
After getting all his nerves in check he left his room and put on the biggest smile he could muster and went to the living room . when he got there he found many adults and children there , he didn't expect so many people to attend his party and thus made him to feel nervous and started shaking , one of the guests saw him and said ' Hey , there's the birthday boy ' .
Everyone looked at him which made him even more nervous . Then his mother said to the guests ' Paul , everyone , lets sing the happy birthday song for my handsome boy ' , after a few minutes they were done singing and everyone showered Hiruzen with gifts . Paul gave Hiruzen a sword and told him that he would teach him how to use it , but obviously this didn't sit well with Mia and the other guests as they were concerned that Hiruzen was too young to wield a sword .
Mia then said to Paul ' love , are you sure that he is ready to use a sword , he can barely lift a brick and I'm afraid that he will hurt himself ' . Other guests agreed with her but Hiruzen told his mother it was fine . The party resumed as scheduled and the adults we busy boasting on how their kids KI energy levels were high and had the potential to rival the infected . This piqued Hiruzen's interest , so he went to his mother and asked her ' Mother , why is it that humans have KI energy? '
Mia said ' I was wondering when you were going to ask me that , i was afraid you had no interest in why we have this power ' . She told Hiruzen and the other children to gather around and she began to tell the story of the origin of KI .
5000 years ago the gods came down to earth and bestowed upon us the power of KI energy . They taught us how the energy worked and how it can be used in our everyday lives , they told humans that KI was more of body energy than outside power . So the best place to truly draw its power is from your body , but to be careful as overusing this power can wear out your body and do some damage to your body . KI energy can be replenished through rest but some people have the skill to draw out KI form other people or animals to replenish themselves .
But as the years past the some of the gods got angry with humans as they felt their power was being wasted on them . Unfortunately this caused some creatures and people's KI to change into something monstrous , their KI became infected with negative energy which caused them to mutate and get stronger . Thus leading to it spreading around the world as many humans and creatures were infected by those that had already been lost , but the spread has been slowed as they were strong warriors in the front lines fighting against the infected .
When the gods saw this they tried to help us but there were some who wanted humans to fend for themselves to see if we would survive without our their help . So they came to the conclusion that they should leave us be and see if we would survive , but one of the gods who seemed to be the leader said to us ' Mortals .. Out of one of you weaklings there will be one with the power to defeat the infected and purify the world to restore it to its former glory ' after saying all this the gods disappeared
And thats why when children turn ten years of age they are to participate in a tournament to see if they have the fall into the category of those who might be the one of the prophecy .
After Mia was done speaking , the other kids dispersed as they had already heard this story so they did not care much , but Hiruzen had a deeper understanding of why the world was in chaos .
He then came to the conclusion that the gods are at fault for the worlds problems and they were to be punished . But he knew that was impossible as they might be too strong for even the strongest warrior in the world so all he could do was to swallow his anger
That day , They way Hiruzen saw the world changed and he knew he needed to get stronger than even the prophecied one
