I read in twitter that the editor first suggested for Ko Yongha to look exactly like Sai, but Hotta refused.
I don't know if that's true (the source is a photo of the commentary, in Korean lol) but if it is, then that's evil genius and I really would like to know how Hikaru would react.
Also there is fanart, which is absolutely diabolical.
(rough google translation)
When Ko Young-ha appeared in the storyboard, Mr. Takahashi, who was in charge, made a surprising suggestion: "Should we make the visuals similar to Sai?" (?!)
I rejected it outright (hehe) and only asked to draw him in a way that shows the feeling of Korea, a Go powerhouse, well.
