[Kurama was half-braced to be brushed off and sent away. Akechi is in a vulnerable place and Kurama is essentially a stranger who knows too much.

So he is caught by surprise and yet dangerously relieved when Akechi's shoulder settles against his. When his phone translates the gestures into a request that he stay. He knows he shouldn't be getting close to Akechi, but he does not have it in him to turn away from the boy's pain.

He lets go of Akechi's hand, but only to slide his arm gently around Akechi's shoulders instead. It's not quite a hug, but it's not entirely not, either, and it's a clear, open gesture of support.]
