The series consists of adaptations of six modern classics of Japanese literature: Osamu Dazai’s No Longer Human (Ningen Shikkaku) & Run, Melos! (Hashire, Melos!), Natsume Soseki’s Kokoro, Ryunosuke Akutagawa’s Hell Screen (Jigoku Hen) & The Spider's Thread (Kumo no Ito), and Ango Sakaguchi's In the Forest, Under Cherries in Full Bloom (Sakura no Mori no Mankai no Shita).

No Longer Human (Ningen Shikkaku) - A high school student becomes lost and alienated. Despondent and aimless, he falls into a cycle of self abuse, depression and drugs that taints his life for years. Told in three chapters, each chapter deals with a different point in his life and the final chapter leaves him standing alone - an empty and hollow charicature of his former self.

In the Forest, Under Cherries in Full Bloom (Sakura no Mori no Mankai no Shita) - A love story between a 12th-century woman and a mountain bandit who abducts her.

Kokoro - A 1914 tale of a young man's life journey during the Meiji era. The work deals with the transition from the Japanese Meiji society to the modern era, by exploring the friendship between a young man and an older man he calls "Sensei". It continues the theme of isolation developed in Soseki's previous works, here in the context of interwoven strands of egoism and guilt, as opposed to shame.

Run, Melos! (Hashire, Melos!) - An updated retelling of a classic Greek tale of the story of Damon and Pythias. The most prominent theme of "Run, Melos!" is unwavering friendship. Despite facing hardships, the protagonist Melos does his best to save his friend's life, and in the end his efforts are rewarded.
