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.
