Sailor Moon – Unexpected Assistance
Chapter I – the Earth's situation - prelude to the intervention
During the Silver Millennium (10-20th century, according to SM English version) a clash between two ancient civilizations broke out, when the evil side, the Dark Kingdom, under Queen Beryl's rule mobilized the Earth's power to destroy the Moon Kingdom.
Queen Beryl, who used to be a girl on the Earth and fell in love with Prince Endymion of the Earth, but her love was unreturned, as the prince had his heart with Princess Serenity of the Moon Kingdom. That broke her heart and turned her to the even more evil queen Metallia of the Sun, who gave her an evil power. Beryl's target was to kill Princess Serenity, and conquer both the Earth and the Moon.
The battle was fierce and painful for the Moon Kingdom, as it had no standing army, with the loss of Prince Endymion, by Beryl's hand as the prince tried to save Princess Serenity's life, and the Princess herself, The Moon kingdom was on the verge of destruction. But then, another superpower of the Earth, which wasn't plagued by jealousy and Queen Beryl's possession, could no longer stand with Queen Beryl's action and decided to step in the way, the Eastern Roman Empire, led by just and strong General-turned-emperor Constantine X. The Roman Empire, although wasn't strong as it had been in 1st century, and Queen Serenity of the Moon, could beat the Dark Kingdom, killed Queen Beryl, and sealed Queen Metallia with high costs—Queen Serenity's life. Before dying, Queen Serenity sent the whole of her kingdom to be reincarnated on the Earth.
In 1993, a clash between the two ancient civilizations during the Silver Millennium was reincarnated. The Dark Kingdom was the first awaken. Under Queen Beryl's rule, they tried to awake their powerful ruler, Queen Metallia, once again to kill the reincarnated Princess Serenity and her soldiers called 'Sailor Soldiers', who lived peacefully in Tokyo, Japan and steal the mystical Silver Crystal, the powerful crystal that was able to possess tremendous power. They tried several unsuccessful attacks, and the soldiers could save their own lives and citizens of Tokyo, the situation gradually grew grim as more and more powerful villains continued to come out to the surface. And when the only surprising-assistant, the Tuxedo mask or reincarnated Prince Endymion was captured, the Sailor soldiers could barely take down later generation monsters.
However, this became the international affair. As the Eastern Roman Empire had chosen to fight against the Dark Kingdom, Constantine X received some wishes from Queen Serenity before her death, and he wished for good and smart succeeding emperors, and eventually, the restoration of the Roman Empire. The Emperor himself swore to fight for goodness and became the protector of the Earth.
The Eastern Roman Empire always had good and proficient emperors ever since, and continued to live through the Middle Ages, and Renaissance, before retaking Rome and reestablishing the unified Roman Empire in 1776, 1,300 years after the fall of the Western Roman Empire. In 1992, it became a powerful state as Julius Caesar had wanted to be, second only to the United States as it still retained its old-fashioned Roman Legions, and eventually became a permanent member of the United Nations.
When the modern world knew about the re-existence of the Dark Kingdom and its domination plan, they didn't just sit and do nothing, especially the Roman Empire, which insisted to fight once again, the Federal Forces, a pure-military organization of the United Nations (As the Supreme Commander of all armed forces in the world), decided to intervene by permitting the Roman Empire to deal with the Dark Kingdom in the rest of the world, yet under the Federal Forces strategically command. Within Japan, The Federal Forces sent a Task group there, under the command of Major General Karl Heinemann of the German Armed Forces. Their mission was assisting the Sailor Soldiers in place of the Tuxedo mask or independently operating if the soldiers were unable to do. But The German Armed Forces itself couldn't fully support the Sailors as it had to operate at least in battalion-sized, too slow to move and too boisterous as their tanks and APCs ran around the city. However, General Heinemann had already selected a smaller, even more-skilled special force team which would be the spearhead operative in this mission.
