Kurama is not expecting a single moment of weakness to become habit any time soon, more likely to bet that Hiei will be back on the defensive once he's feeling better. It isn't something he can safely even guess at with the children present, for now, just observing how things play out and content not to interfere in their socializing.

Without their company, several things could have been said to that borderline shy response, most notably that he'd also somehow fallen asleep without realizing, but Kazuma starts instead - his uncle’s face with his father's personality - and that shuts the fox up before he can even think to speak.

Hiei had the excuse of exhaustion and his injuries, at least. Kurama was the one called out by that announcement, having been fully awake and able to do something about it at the time, yet allowing it to happen, despite this.

“Yes, his day has been taxing enough.” Kurama adds, shooting Kazuma his own warning glance at the increased discomfort in the room with his remark.
