A new teacher assigned to Class E. She is overly sweet to the boys but cold to the girls. She usually wears glasses but tries to look cute with contacts and makeup (though it doesn't work). She wears mini-skirts, which are clearly not appropriate for a teacher. A self-proclaimed airhead. Even if someone raises their hand because they know the answer, she only calls on the boys. She intentionally trips toward the boys. Her physique is 'plump' to put it nicely, or 'fat' to be blunt. Since she is technically a teacher, she can actually teach. She is bad at PE. She adds heart symbols to the end of her sentences. She uses polite language with the boys and calls them by their first names with '-kun'.
