Analytic to a point, the fox was all reassuring smiles and gentle kindness that radiated deep within his bones as he took note of the subtle gestures given by the child. Yes of course, its not so out of sorts to be curious about a fox. Even less so to be curious about a fox like him. Kurama was content to let the boy's curiosity grow until he wished to ask him his question, until he wished to speak his mind. No matter the training of a Shinobi, it never applied to Kurama himself as he existed beyond the understanding of man and so their ways were not his own. His pointed ears flick forward at the stuttered words and a pang flourishes in his chest. Ah but y' are, dear child. Y' are so sorrowful I could feel it ten miles away. The words never left his maw as he watched in quiet reverence for the strength of humans. To endure the death of one's parents was never easy nor was it something one should bottle up. Yet he'd always known Shinobi to do just that, to never mourn properly concerning their fellows. (Ridiculous human notions.)
Perhaps it was shock, maybe fright when he'd stood up and towered over the child-- but it influenced a break in the dam so carefully constructed to withhold his emotions. The tiny fists all but specks in comparison to the weight of his own as he reaches forward to claim them in his gentle claws. "Now now.. Don' go hurtin' y'er eyes t' stop a natural process," he spoke in softer tones with warmth and reassurance as present as his ears were. His tails moved to wrap the smaller body before him and raise him up to his height and cradle him in their soft tendrils. "Y'er parents may be heroes but that doesn' mean y' can't be sad, it doesn' mean y' can't mourn 'em. Y' can regard them heroic and still be hurt that they're gone. Otherwise, how're y' ever gonna move on fr'm it?" He does not try to say it is unwise to bottle it up, does not try to discourage him from his current actions. Rather, Kurama tries to show him that he is allowed to mourn. "Shinobi haven' always been so emotionally strained, little one. Once upon a time they mourned their lost ones an' mourned their hearts as well. A very long time ago, it was considered inhumane if one did not properly release their sadness t' th' skies f'er their loved ones t' quell."
Yes, he wanted this little one to be well and have a heart not full of resentment and sorrow but rather full of joy and understanding. Though he knew not how his parents died, he knew that there was no reason a child so small should ever feel a weight so large upon his shoulders. Even if he was a old enough to learn to kill, that did not mean a thing to the fox. After all, a husband would mourn a wife and a mother would mourn a child no matter what their title or job was. "Y' jus' cry y'er heart out an' they'll hear it. They'll understand it an' they'll make y' feel better. 'Cause even when we can't see th' stars, they're still there, an' y'er parents are still there with 'em. So mourn, little beastie. Mourn until y'er heart is light again an' this ol' Kurama will stay with y'."
