There is a glint in the eyes of the assembled shinobi. He recognises it, because the same, almost fanatical, loyalty glazes his own whenever his clan is involved.
As far as he knows, he is not the kind of man to inspire such devotion. It is, in a way, humbling.
Perhaps, just as he saw in them Hashirama's legacy, they saw in him a lick of his fire. Ash clogs his throat, and he blinks.
For the first time since his brother's death, the cloak and hood feel right on his frame, not stolen from a corpse. He fingers the rim of the hat, words fuelled with a warmth usually reserved for family.
"I am honoured to be your Hokage."
The ensuing silence is deafening in its reverence.
Notes: In contrast to the induction ceremonies of the other Hokage, I can see Tobirama's being especially sombre due to the circumstances of him inheriting the position in the first place.
