The expressions/phrases that involve 気 (ie: 気になる, 気にする, 気がついた, etc) are pretty well documented online. However, it seems difficult to find how to use 気 outside of these. For example, I recently encountered:
(saying that Yuuki seems to be running away with the game)
(asking "what will you become?" after another character says they will lose their human form)
In the first example, 気 to be functioning a bit like みたい or よう, while in the second, I'm not exactly sure what it is doing.
While I'd like an answer addressing what is being expressed in these examples, I would also like a more general coverage of how 気 is used outside of expressions.
