Mayu Ooba

Mayu Ooba is an instructor at the Tokyo Art Institute cram school that Yatora Yaguchi attends, preparing her students to apply for art schools and their entrance exams. Ooba has short, bobbed black hair that has square bangs hanging over her forehead, thin eyes and she is very tall, to a point where she reaches the top of most door frames. She is usually seen wearing an apron. Ooba is a highly eccentric, carefree and wise teacher who tends to be blunt and loud, and cares deeply for her students and her craft. She often says random animal trivia, more so during stressful times.
