Ethics, or the study of what it means to live, and the principles that shape our sense of right and wrong. It’s a subject you might go your whole life without learning, and never suffer for it. Yet within this classroom lie the truths essential to understanding ourselves. Enter Mr. Takayanagi, a calm yet enigmatic ethics teacher who faces the struggles of his students head-on, guided by his own unconventional beliefs. A modern, thought-provoking story of youth, morality, and the teacher who dares to challenge both.
