My goal is to solo the xenosaga trilogy once with each character

I must be the only person who didn't actively dislike Xenosaga 2. Oh there were some things I thought were jarring, like the sudden change in art style especially for Shion (not to mention the weird personality shift) among many things I didn't like about the game. But once I learned how to juggle enemies the battle system became super easy and fun. It's the same strategy every time and I'm fine with it.

Plus since I really liked Jr I was into the whole Rubido-Albedo backstory, facility experimenting on superpowered kids and how they break out etc.

That does raise a question tc how exactly do you deal with the Xenosaga 2 portion of the game where you only play as Shion?
