That’s Yukizane, always thinking.
I really like this dude. He reminds me of Iroh from Avatar
They would get along . . . Iroh and Yukizane need to meet up for a game of Go and a pot of tea . . .
…And complain about “kids these days”…
The art here reminds of Avatar in general. Like some one said he look like Iroh while she look a bit like Azula.
