Tsugunai

After the death of their parents, Nana and her older brother were left completely alone. However, trouble never comes alone: one day Nana is attacked by a group of influential businessmen of advanced age who rape the girl. Thanks to their connections, they manage to go unpunished. As a result, Nana suffers from psychological trauma, and her brother begins to be overwhelmed with anger: at the bastards who did this to her sister; on himself, because he could not protect his sister; to the whole world, which turned out to be so unfair to them. He decides to take revenge on the rapists and gets a job as a teacher at the women’s academy, where the daughters of guilty businessmen study.
