That's the general idea, but it could even be them just being able to better accept other people who act the opposite to them or to see that passive people can still be good in a fight. (at least for Akari, since she probably wouldn't act calmer just from this :P). I also mentioned in a prior comment that they can switch partners around every few days to allow them to interact with different people. So Kotaro/Akari can be just one of the interactions your character can learn from. I think this will help flesh out our characters and give us more to use when we have more battles in future arcs.
