"Of course not," Koumyou agrees, if a lot less vehemently. "I'm nowhere near that big of a hypocrite. I'm still perfectly willing to be your adoptive father, if you want one. Or just your friend. Or nothing at all."

That was the choice he'd given her after Diagad, if in vaguer terms. He'd liked having his kids in that illusion. Both of them.

"I admit I would have hesitated before Diagad, but only because I didn't want to... basically replace Kouryuu? But he liked you enough that he told me I'd better look out for you, if not in those exact words. Something-something 'the little twerp'."

Which he'd probably called her in the illusion, but had seen no reason to stop once he was out. Permission given to his father from multiple angles, for someone fluent in Kouryuu-ese. Which, of course, he very much was.
