Sure apologizing was the morally right thing to do at that moment, but it also happaned to be the most beneficial move for her in the situation.

She was already busted, so trying to pin the blame on someone else wasn't an option. Even for someone who only cares for themselves, apologizing would have been the best option to get out of the situation with the least damage.

But even if we knew it was honest, does it change much?

She still risked the lives of five Humans and three Exceeds just to protect her own reputation. A simple apology won't just magically turn this selfish action into a benevolent one.

Don't get me wrong, I like Hisui. That she is not clearly good or evil makes her a very interesting character. And it makes it had to predict what she might do next, since we don't really know her motivation for her actions.

Because of all that I'm hoping she'll make a return into the story in the future.
