“When they meet their limit.” The children were raised in a thankfully peaceful Human World, but try as Hiei might to remind himself of that fact, he does not want to make them weaker by not pushing. Who knew what could rear its ugly head tomorrow, really, what threat may decide to try and level their sights on the human world or what small family Hiei does have. Not all of human world was as protected as Genkai’s, after all. Beyond that, should he not return from the demon world one day, they needed to be able to protect themselves.

That he leaves unsaid, of course. Hiei’s comfort with his own death, as a child that hadn’t even been meant to survive, sets them all on edge.

“He will be.” Hiei knows of them all that Kazuma doesn’t cowl to his threats. After all, he tends to be eager for training more than worried about what Hiei may have for him that day. Learning to control his natural fire had come easily enough, but making him stronger and more precise took time. Beyond that, he can’t count how many times now he has discouraged the half-demon from attempting to summon flames from the depths of the demon world.

In time, but not this time, many times over. The last thing he needs is his nephew with a charred arm much like his own and Yukina’s justified worry to follow.

Hiei meets Kurama’s assertion with a level stare, finishing his rice ball in the meantime. Not that it ever stopped him from speaking through them before, but.. he is in no position right now to try and throw his weight around.

“You never listen when told to mind your own business anyway.” Whether it concerned him or anyone else, before all this had begun. “So why waste the breath?”

Though it does beg the question of what Kurama came for, then, red eyes inquiring as he wiped his hands on his pants in true Hiei fashion.
