Agatha comes as a tall and slim woman, with refined facial features, and blonde curly hair with a short cut whose ends are split into two long low-twintails that reach her hips.
She wears a black mini top on her head with a flower (presumably a rose) ribbon. As well, a corset dress with its upper half being red with black borders; and its skirt being black, accompanied with a white short jacket with a tiny black tie. She also wears white gloves on her hands, and white long boots.
Being completely refined, Agatha possesses a lady-like attitude.
And Then There Were None (そして誰もいなくなった, Soshite Dare mo Inakunatta?).
- Her ability name is the US Abroad name of her most acclaimed book released in the UK known as Ten Little Niggers after the British black-face nursery rhyme. The name was later changed to the last 5 lines of the nursery rhyme, and thus was released in the US as And Then There Were None
