Histoire has medium-length blonde hair in two pigtails tied up with teal ribbons with a purple and white headdress on her head. She wears what seems to be a purple gown along with designs that have orange coloring with a teal bow at the top. Her leg-wear consists of white stockings and purple shoes with pink circles on the center.
Histoire is shown to have a very cheerful and frequently uses emoticons at the end of sentences when speaking. She is very sweet and also very intelligent with strong sense of right and wrong. It often takes her a while to find the information needed by others within in her tome. That being said, avoid calling her slow, because she will turn into "Pissty", as Neptune says. Much like her counterpart in the Hyper Dimension, she has a very low tolerance for laziness and foolishness.
