I think that black mist is his greed.
When his companions were taking treasures, They show their greed as the black mist.But only he didn't.
And when they left, he turn to look at where his brother is. Then the only one showing greed is him. I think he has a secret crush on him? Because he thought "how dare he leave without my permission".
Man it was confusing tbh.. sometimes it was hard to understand who was speaking because the dialogue bubble didn't have that tail thing ()
Also, what happened to the brother? It's incomplete.
But the Art was beautiful
