Synopsis

There is a high school where students can take an elective course in ethics. Despite their innocent looks, the students that attend the class have serious problems of their own such as self-harm, bullying, drugs, non-consensual sex, and seem weighed down by their troubles. Takayanagi (Yamada Yuki), the mysterious teacher in charge of this elective course, offers words on ethics and philosophy to them. When applied to the students of today, these words written in what seems like a boring ethics textbook, help them deal with their own problems and get through life.
