Cha-chan is Michiru's best friend, and is the one who first introduces Michiru to the Fun Fun Factory. She has been there before, and is recognized when she goes there. Cha-chan's 'look' reminds me of Tomoyo from Card Captor Sakura (very beautiful!), but Cha-chan is much more aggressive and sharp. Her attitude seems a bit sarcastic to me, and she is not the type that can be easily fooled. Yes, Cha-chan is quite perceptive! I like her a lot!
