Yeah, I'm thinking I may just go the route of ignoring icons and just using descriptors to clue people in. If they don't catch it, oh well!
Heh, and no worries! Kirika's actually a good fit from the little I know of Ryo considering she's part of an assassin team named Noir although Ryo's a bit more expressive and outgoing then Kirika. Kirika doesn't exactly get the social norms having grown up separated from society.
