Given that it's the final episode, I have criticize the lack of meaning in these choices.
SPOILER: It doesn't matter if you're good or evil in this game. It only makes the game easier or harder to beat. Aki does nothing for you against the final boss. Win/Lose. It's irrelevant.
If there's merit to be had, it's that the system was a little better than in previous games, making your partner seem more relevant. However, in the end, it's just a story dump that might as well had no choices.
