Eriko
The school nurse at Takuya's school, who doubles as his homeroom teacher. She stands out among the staff—partly because she spent time living in Europe, which left a mark on her personality. She dresses differently than most people around her, speaks more directly during work, and generally carries herself with a distinctly un-Japanese frankness that makes her memorable. Her time abroad basically shaped who she is at school.
