Оно Мінахо

Teacher at Karasuno High School. She is often seen teaching Hinata's classes, overseeing tests, and working in the staff room. She supervises Hinata and Kageyama while they took their make-up exams and encourages them to do well afterward. When the Karasuno boys' team won an important match, she joined the students in opening the windows and cheering to welcome them back. She attends the Karasuno vs. Shiratorizawa match and tells the Vice Principal that their hastily-assembled cheering section had not been practiced enough.
