He tells it like it is! To Cissie, his honesty's actually quite refreshing in this world. Sure, he can be rude at times - and he's definitely not on the nice side of things - but she doesn't mind. Grimmjow actually reminds Cissie of one of her best friends. :>

So right now, she's not sure what to make of him either. He's different, but... not a bad different.
