Lets assume different scenarios where each UTY main character (plus kanako and chujin) becomes the knight/has to be the knight's replacement because they didnt show up individually, with some ground rules being laid out to them such as "cant fight the fun gang until chapter 3" and "cant simply create a bajillion dark fountains and win easily" or "cant give out info like the bunker's codes", but they can improvise and do whatever stuff they want outside of those simple rules, how well would they perform while being in the knight's role? Would they fumble hard? Be a cocky showoff all the time? Or be an actual threat who may or may not manage to win?
