Anno was startled when she heard Hikaru's words, she didn't understand what was going on or why he had made such a decision. However, that was not a bad thing, on the contrary, it was a very good thing.
Anno asked, "Why?"
Hikaru pondered for a moment, then said, his voice filled with seriousness that surprised Anno: "Because they are treasures that need to be protected."
Anno was surprised to hear that, but then she burst into laughter: "Hahahaha… Kiki, you're so weird, this is the first time I've heard someone say that mixed-blooded people are treasures that need to be protected."
Hikaru also smiled, perhaps to the people of this world, mixed-blooded people were seen as dirty or despicable beings. But to him or many men on Earth, mixed-blooded girls were treasures to be protected.
Anno was happy that Hikaru didn't discriminate against mixed-bloods, on the contrary, it seemed that he had a soft spot for them.
