Ryu could see the confusion on the woman's face, but he only smiled. This could be considered to be the result of two things.
The first was that his wife was still a bit unhappy with him and wanted to teach him a little lesson. Giving him a difficult task was definitely in line with that.
The second was that this was how he and Ailsa always did things. Which one of the things that they had accomplished together couldn't be considered to be normal? She had high expectations of him, and he wouldn't have it any other way. This was only natural.
After he had these thoughts, Ryu pretty much tuned out the rest of Rinushka's explanation because he already had his own guesses.
There were a lot of odd things about this world. The suppression of the Human Race and the weakness of the Beast Race were the two things at the forefront of his mind.
Of course, he already had an explanation for both… and they couldn't be considered to be satisfactory.
