Completed the game at lv 99, don't know if you can do it without being max level. I did it with the black clothed man 3 times, lost to all the arena groups once, barbarians, knights, Hero party, and then Demon Generals, so right there is 7 cgs, but I also lost to the hero party one more time so I saw 8 cgs and I have no idea what I'm supposed to do to see the rest, You can only lose to the Demon generals once before you get a bad end game over. So I can likely get 2 more cgs by losing to the knights again and the barbarians but I have no clue about the other 5... Anyone got any ideas?
Edit: Losing to the barbarians and knights twice does nothing. Where the hell are the other 7 cgs...
