I'm glad you enjoyed the game and understood the true meaning of the story. As for CC, I'm not super sure what you mean exactly and so to avoid me spoiling things for others here I would suggest you check out a game in the series called " CC: The Girl Who Chants Love at the edge of time ". here is the link for it : https://fouzi94.itch.io/cc-the-girl-who-chants-love-at-the-edge-of-time
It's a very short game dedicated only to CC and her origins/identity.
CC also appears in other games like "Goodbye Time Traveler" but just as a side character for obvious reasons.
