Leon wanted to ask why Yuki waged war against them, but it would be better to read the registers... there was a chance that everything written there would be the only information that would make Yuki and Ren look like they were on the right, but Leon would notice that. He wouldn't believe such obvious biased information... that being said, Leon couldn't read Japanese, so Ryoko had to read for him.
"The first thing registered is the actions of our late emperor, the prince, and Your Majesty Yuki actions," Ryoko said. "After fighting for a month to clean the area around Tokyo of monsters, we recovered the city and started to rebuild our capital. Eighteen months later, some spies stole water dragon scales from us... the prince tried to stop them and died in combat."
"I already know that," Leon said.
"... I think this is late Emperor's handwriting... it is written here that six months later, the Emperor heard about an American had arrived and started to work with one of his advisors... his name was Leon, and the advisor was Ren," Ryoko frowned.
"That did really happen?" Ren frowned. "I don't remember that..."
"What do you remember about Makoto?" Leon asked.
"Our Emperor was a good man who would fight on the frontlines to protect his people," Ren answered. "He was very honest and capable."
"What else?" Leon asked. "How old was he when he died? What were the powers of his sword?"
"... I forgot." Ren looked away.
"It is obvious that we can't trust your memories," Leon said. "You may continue."
"... The man called Leon worked together with Ren, and then he cleared five dungeons in order to obtain His Majesty cooperation." Ryoko said. "A few months later, Leon returned and brought the people that cause the prince's death."
"I thought father disappeared one day and then suddenly returned after finding the killers himself," Yuki frowned. "Someone must have faked these documents..."
"It is said here that Leon and his friends protected a city called Las Vegas from demons... a very dangerous race of monsters," Ryoko said. "This is the last register that was made with His Majesty handwriting... I remember now... this book was His Majesty diary, and I decided to use it as the first register when it was decided that I would work here, organizing documents."
"When that happened?" Leon asked.
"I think we found these twenty years after the death of His Majesty," Ryoko answered.
"Twenty years... I guess the things that happened before I disappeared aren't written here," Leon starts to bit his nails.
"... No, it is here... I registered that His Majesty and Leon disappeared and then je returned several weeks later with princess Yuki," Ryoko frowned. "She had been kidnapped by someone... one of his Majesty advisors."
"Kidnapped? Me?" Yuki frowned. "This is obviously a bad joke... You must have written this when you were drunk, Ryoko."
"I can't imagine Your Majesty getting kidnapped either." Ren nodded.
"... Continue," Leon sighed.
"It looks like that I wrote that after hearing about a massive monster invasion in Brazil, the man called Leon disappeared, and there is no mention of his return," Ryoko said. "It looks like Your Majesty, lord Ren and the people of America worked together to find him for quite a while... the group searching for him was quite small, but they investigated even the worlds on the other side of the dungeons."
"Well, well... I guess some people missed me," Leon shrugged.
"I don't remember doing something like that," Yuki said.
"I don't remember either," Ren said.
"Most nations of the planet were working together, but China and India didn't want to become their allies because they thought the other nations didn't have the means to contribute with them," Ryoko explained. "Although the person called Leon worked hard to make several countries work together, things didn't progress after he disappeared. Mostly because his friends were looking for him... but they stopped looking after ten years."
"Well... I guess it is only natural." Leon said after a long sigh.
"It looked like his friends were forced to stop looking for him because the number of dungeon breaks was increasing," Ryoko explained. "After a while, it looked like the inhabitants of the nations that were suffering because of dungeon breaks discovered that it wasn't happening by chance... people of their own countries were causing dungeon breaks."
"What? Why?" Leon frowned.
"It is not written here... It was impossible to identify the people who caused the dungeon breaks because that their goals were unclear," Ryoko said. "The most obvious answer would be that they wanted to cause more deaths, but it wasn't a motive that makes sense. Since it looked like they had no goals and only wanted to cause destruction and death, people started to refer to them as 'The Fallen.'"
"I think I heard something about that a long time ago," Yuki said.
"Me too," Ren nodded.
"Can't you do anything but agree with her now?" Leon frowned.
Although Leon got caught by surprise, he soon understood what their goal was... it was to increase the amount of mana Earth could handle. The more mana the planet has, the faster the second stage of assimilation would begin.
"It looks like that the lizard bastard was behind the dungeon breaks, after all. William and the others wouldn't be enough to create the situation he wanted... so he probably promised power to random survivors, in exchange they would cause the dungeon breaks... it makes sense, only someone powerful or has some useful and rare skills could do such things and still keep their identities hidden."
"The fallen kept doing that for ten years... but then they suddenly disappeared when the world started to change," Ryoko said. "New dungeons appeared, and more powerful enemies invaded Earth, while some dungeons stopped working. We call it that... the start of the second great war against the monsters.
