Did a few edits. Thank you guys for clearing things up by the way.

tl;dr for the edits.
- Mentioned that Jack was the representative of the Champions during her recruitment.
- Explained that the Champions would give her the augments in exchange for her set of skills.
- Instead of faking her own death, Xoxi left the Champions a few years before Nagoya, and is back to help restore their reputation instead of her faking her death.
