Cassi is a very smart girl, talented with the pencil and pen, and is good at gymnastics and loves animals. Cassi is carries along a diamond cross neaklace and tries not to lie. But apart from all of those, Cassi is tough and loves to have fun. She doesn't bother to listen to most of Sora's advice, or for that matter, any of Tai's advice, either. Cassi is somewhat ignorant, and doesn't pay attention to what she's told in the DigiDestined group, but she is usually able to figure it out on her own, anyway.

Cassi was given the crest of Purity. This shows that she is very pure, and belives in having no sins and her crest of Purity suits her very well. Cassi is almost always the one who has the pure answers to the confusing puzzles in the Digiworld.
