Maria is a sweet and somewhat childish person who is kind with all her friends and her chat. She can be eccentric and mischievous at times in spite of her innocence, but her good natured (and relatively wholesome) personality ultimately endears her to her fans and cohorts, who often treat her as an adorable little sister.
She often streams relaxing games.
She has short light silvery hair with pink and purple streaks in a ponytail and a heart shaped ahoge with a pink eye and eyepatch. She has a short white jacket with long sleeves and multiple pins with a black top and light plaid skirt with mismatched stockings.
