One hundred and several thousands of years ago in Earth time from now…
The domain of such days were different than nowadays and there was no such strong relationship as the Galaxy Federation, and there were only small alliance of planets and star systems by numbers of tens of thousands. Related to the undeveloped techniques of driving systems from a star system to others, the war between nations did not mean so much at these ages. There were several local conflicts between those who faced each other, but most of the nations turned their view to unclaimed areas of the space.
It was the days for the pioneer.
Many nations were founded, developed and ruined. The domain of the intelligent life form spread through the galaxy and at the last, two large powers appeared; one was the federation, "Jurai" and the other was the alliance, "Seniwa". They had high technology for space driving and if they had tied together, it was possible that they would be the core for the birth of a galaxy federation. However, these two nations were under cold war for a long time. And though they were large groups, looking at the size and number of all the federations spread in the galaxy, it would be hard to say that they had the power to found a galaxy federation alone. Though there was one more reason, which prevented the connection between the nations. It was the space pirates.

Washu was found in such days.
The planet where she was found was named "Kanemitsu". It was located in the far end of the Jurai territory and as it had fertile earth, it provided food from agriculture and fishing. On the other had, this made it to be the target of the pirates and other nations. As Kanemitsu became more important as a front supplying planet, the third generation Royal tree started to reside there to protect it from others.
Washu was floating in the air with three gems with her when the rector and others saw her in front of the abbey.
'It was just after the rain stopped and the sunshine through the clouds covered you. You were like an angel, ' said the lady rector.
She thought that Washu's parents still might be around and collected information through the network of the town but none could she get. Further more, she couldn't even find a person who saw Washu on her way to the house. They tried their best to find where Washu came from for all these years but it ended in vain. Washu and the three gems were checked before she was allowed to stay with others in the abbey. Though she was flying when she was discovered, there were no answers from the supernatural powers checks. And for the gems, they were judged to be just some crystals.
Several years later, they happened to find that Washu had the ability to change her body age. And she had her second check for supernatural powers, which ended to rank her as class "C". Because of this, they didn't pay much attention for her powers, but they were interested with her intelligence. She cleared by 4 years for the basic course, which usually took 10 years for others and when she was 15 years old, she mastered all the basic studies of the Academy and got the special scholarship and entered the Jurai imperial Academy without taking the entering examination. What is more, from the propriety test, she was recommended to enter the department of philosophy, which was the top of the Academy. However, considering the mental part of her, she was told to wait till she gets 18 years old to actually enter the Academy.
For Washu, the final topic of her interest was the three gems. They were told to be only some simple crystals but she knew that they just didn't have the ability to figure out what they were. Washu herself found that she had more power than a class "C" supernatural powers. She had a bottle in her room, which included tiny lights drifting in it. Each of those lights was a universe. Not a hologram they were, but real ones. She was able to generate them based on her basic studies. Finding her real powers, she also noticed that the three gems also had more secret powers in them. However, at that time she was unable to find out what they exactly were.
"…Yes, I don't know them from my knowledge. But…"
She knew that she would be able to figure out what they were if she releases her inner capability. And also to know who she really was.
But she didn't.
Someone inside her told her not to do so.
"If you do so, it would be a repeat again."

The high rankers send her off when she left planet Kanemitsu. She was served as a VIP and the journey was quite well.
However, during her trip to the Academy her ship was attacked. It was the space pirate, the Shank guild. And an intruder in the ship tried to kill Washu. Before she was to be slain, a Jurai warrior from one of the imperial families managed to help her. They had guessed for such a situation and mounted two center cores of the imperial ships in the ship, which Washu was boarding. Finding this the intruder self destructed in order to murder both of them. However, three Light Hawk Wings protected them from the explosion. The warrior was surprised for this as his ship's Light Hawk Wings were set outside to protect the ship from the pirates' attack and he had no idea from where it appeared. So was Washu suprised. They didn't notice, then, the three gems glowing in Washu's pocket.
The ship was then safely sent to the Academy, while the Shank guild was thrust by the Jurai force. However, an accident happened during this attack, which Washu was to know several years later.
