Benares is a very cold, callous, and dispassionate figure, and is rather aloof, brooding, and indifferent. She refers to anyone who is not of the Honkai as "fish" for being just one in the middle of billions more. Despite this, she is not particularly violent, and will only fight when provoked or ordered to by Sirin herself. Even with her cold nature, she genuinely cares for Sirin who calls her Bella.

Has blue eyes with grey-blueish hair, and parts of the power of the Herrscher of Thunder.
