[If Kimigiku were here, she would surely call Kaoru out right then and there. But she isn't - and Sen doesn't share the deeply ingrained suspicion of him that her bodyguard does - and so while she does notice the sharpness of his smile, she is content to let it be for the moment. He has grown into a very dangerous demon, but isn't that exactly what she had made him promise he would do all those years ago?

There is no one who can say that he didn't become strong enough to fight his way out from under that clan's thumb.]

Ah... yes, that's right. Congratulations are long overdue, are they not? ["Congrats on slaughtering your entire clan! Many happy returns!"] I'm pleased to see that your circumstances have changed so drastically. [Because, let's be real, any change would have been an improvement to his prior situation.] Congratulations on becoming the head of the clan. It has been many years since that clan has had a leader of your caliber.

[It's also been many years since the clan has had a head that wasn't a fucking psychopath, but she can't really congratulate him on that because that's one cycle that hasn't been broken. Unfortunately.]

...I suppose I should also offer you my apologies for not congratulating you sooner.
