Miyuki Igarashi is the homeroom teacher of class 1-A, and has a reputation for being a hard drinker. She is frequently tardy or daydreaming in class, either because she is suffering from a hangover or because she is simply bored with teaching. Miyuki is known by her students to never dress up, nor wear makeup and to almost always reek of alcohol. She frequently stares out the window of her classroom and says that she wishes she was a cloud; a wish that often is only heard by Shu. Often, the empty seats in her class are replaced with Japanese-style scarecrows in the anime episodes.
