Elna Stongs

Race: Human Elna was a mercenary from the ages of 7 to 24, but under some circumstances, she becomes a teacher in Hero Academy just last year. She teaches the S-Class students and she is Noir's teacher. Elna is very harsh with her students, but she doesn't mind using her sex-appeal to motivate the male students, getting to the point of rewarding her students by sitting in their faces.
