Azuki is the oldest of the Minaduki catgirls. She is quite full of energy, but can be rude and has a knack for badmouthing her younger sisters, despite supposedly being the most grown up. Her breed is a Munchkin Cat.

Azuki is energetic and lively, but this energy is directed at insulting her fellow catgirls and getting into fights with them. This somewhat gives her a more 'tomboy'-esque personality than the others. She also has a weakness for food - she'll unapolagetically scarf down anything she is presented with.
