Prologue/Chapter 5:
Kuro was a little boy with spiky black hair and black eyes. He's seen wearing a regular t-shirt with a jacket overtop that shows the Bolt Bloodline insignia.
Chapter 21:
An older Kuro has the same spiky black hair and black eyes, like his younger counterpart, but is in an Imperial Guard uniform.
From the little we've seen of Kuro, what can be inferred is that he's a person to put his family first before himself, similarly to his father Machmino and brother Hydama. This is reinforced in Chapter 21 with a conversation between Princess Aya and himself where he's specifically concerned with Aya's intention with her question knowing how her innate kinetic works.
His birthdate is stated to be May 6, 1996.
His favorite food is Barbeque wings.
He is 6'0" or 183 cm.
He watches anime in his spare time.
In the fanbook, it was confirmed Kuro had many suspicions on Aya's plan to use her innate kinetic on Hydama after asking him a series of questions about him.
Kuro's whereabouts are currently unknown but he is theorized to be the masked advisor or "redacted" based on context clues.
