Because of her tiny stature, Aizawa Inuko is asked for her ID incredibly often. Her young appearance is a source of insecurity and betrays how miserable she is. Now on the eve of being thirty, she's feeling like she missed out on her youth and that she's hopeless going forth. She's not a terrible teacher, but trying to drown her sorrows in alcohol and irresponsible relationships might not be the best choice for her. She only gets three hours of sleep on average.
