Honoka Kanemitsu

Post-war Yokosuka, Kanagawa Prefecture. Adults who are swayed by the US military stationed in the country and swayed by US intentions cannot afford to care about children who should be protected. The war orphans, who had no choice but to survive on their own, were used to shining shoes for American soldiers, picking up cigarettes, and sometimes committing crimes. However, at some point, they came across a "cleaning" job. They work hard instead of committing crimes and earn money by being appreciated by people. The orphans begin to regain their smiles through experiences that make them feel like they should be alive. The children started to have a modest dream of "renting a house and living" with their own earnings, but they were attacked by an even harsher reality...

In the spring of a new semester, a "ranking" is sent to Class 2-D. It clearly shows the rankings of all the students and the homeroom teacher. The one who ranks 1st is Himeyama Tsubaki, a kind and popular honor student recognized by everyone. But one day, without any warning, she commits suicide. A few days later, everyone in the class receives a suicide note from Himeyama, and from that day on, the class begins to fall apart.
