If we don't know how many times she's regressed (and it's probably not on purpose) she probably has a goal that she's never achieved. Most likely that goal requires her to become the crown princess and have lots of money and authority, which is why she's trying so hard. Could also be likely that a lot of it is she's stuck regressing, and then is also stuck in her "role" (the mage guy mentioned a 'game' right?) if it's unavoidable she's just dedicating herself to this one thing time and time again because that's her 'role'.
