In Unfinished Dream of All Living Ghost, the first half of the selection menu characters (up until Yachie) have the "regular" question mark expression for the main player. The second half (from Yachie onwards) have the "regular" question mark expression for the opponent. Whenever the characters appear as an opposite role, the portrait is simply mirrored, resulting in an incorrect display of the question mark symbol.
This post showcases the first half of characters. I'm not sure if I missed it, but couldn't find any instance of 2P Tsukasa having the surprised expression. Please let me know if you notice it anywhere.
Below you can see the character selection menu for reference.
