Mawata is a girl with light-colored hair that reaches down to her shoulders, her straight bangs parted to the left, tucked behind her ear, and left to fall over her eye on the right. She has round, dark eyes that slope slightly downwards towards the sides of her face, framed by rather long eyelashes and noticeably dark eye make-up, their light pupils appearing to be shaped like small stars or clouds.
As well as the standard female uniform for U.A. High School, Mawata wears a pair of puffy, cloud-shaped earrings.
While Shota Aizawa leaves with Hizashi Yamada to Tartarus, Class 2-A takes notice of how grumpy he looked before he left and compares his expression to that which he wore when expelling someone. While her classmates are sharing their thoughts, Mawata states that admittedly it was bad that people had to be expelled, but that it also helped the class grow overall.
Overall Abilities: Mawata's abilities are currently unknown, however, as a Hero Course second year, she has undergone more than a year of combat and rescue training from the best Hero school in the country.
Unknown Quirk: Mawata's Quirk is unknown, however, given that she is a Hero student, her Quirk is likely very strong and well trained.
