If I remeber correctly In the manga she's alot like ichigo who transforms into a cat. Her transformation is useful tbh. Ichigos transformation actually is a sign that her powers are glitchy since she fully turns into a cat instead of gaining some attributes of her animal, Ryo also has this issue as well. That's why, in a la mode, she isn't part of the team as much.
I prefer the old design tbh, but the pencil skirt is a nice touch. I just dislike how they make Zakuro too girly, but I think Mint was done very well with the redesign.
It only ichigo , lettuce and Ryou they can turn to they animals froms such as ichiko and Ryou can turn to be full cat from but ichigo she can turn to be cat and cat from have tail and ears , lattuce can turn to be Neophocaena phocaenoides (when she live under water she can use Neophocaena phocaenoides tail like mermaid swimming)
