御堂 綾

A science teacher feared by all the students, she has a cool posture that never breaks. With a sharp look to her eyes and her default look being a straight face she is seen as a unsociable teacher.

However she is actually quite the opposite of how she is portrayed, she is very prone to worrying and lacks self confidence. Her timid nature is hidden by her neat and together appearance.

Narumi is the only one who knows her true nature and member of the opposite sex she reveals it to.
