35-sai no Koukousei

During the new semester in April, a woman suddenly appeared at Kunikida High. She was to be a new student in a class for 3rd year high school students. The other students in the class wondered who she truly was, and what her true intention for going back to school at 35 years old was. She did what ordinary high school students were expected to do, i.e. wearing school uniform and doing homework. However, she was clearly different. She went to school in an expensive car. During break time, she smoked with a teacher. After school, she drank beer. No one knows what she was up to, but they know, she was able to change people.
