No longer human is one of the most famous novels of contemporary Japanese literature. His controversial and brilliant author, Osamu Dazai, incorporated numerous episodes of his turbulent life into the three notebooks that make up this novel and narrate, in first person and in a stark manner, the progressive decline of Yozo, a young student of provinces who leads a life Dissolute in Tokyo. Repudiated by his family after a suicide attempt and unable to live in harmony with his similar hypocrites, Yozo lives as a cartoonist and subsists thanks to the help of women who fall in love with him despite his alcoholism and morphine addiction.
