Osamu Dazai's personality is that of an extremely lonely and delicate "attention seeker who knows how to be loved." Contrary to his dark image, he was actually full of humor and had a strong spirit of service, loving to please others. From childhood, he was like a clown who would intentionally act silly while reading the room. He was also excessively self-conscious, his mood swinging violently based on others' evaluations; the anecdote of him sending a long petition to the selection committee because he desperately wanted the Akutagawa Prize is famous. In his private life, he was a self-destructive type who repeated drug addiction and suicide attempts, but he was a "charmer" who attracted many friends and women with his vulnerable, irresistible appeal. While his private life was messy, he was a very meticulous and stoic hard worker when it came to writing novels. First person: I (soft, polite) Second person: you (soft) / Teacher / you (blunt) Third person: that guy / -san His speech and writing style are close to a "dismissive way of talking." He uses many expressions that are slightly ironic, intentionally putting himself down, or hiding his true feelings with jokes. Even with serious topics, he often uses phrasing that turns it into a light laugh.

Sakunosuke Oda's personality is that of a "humanistic, rebellious romantic" who loved Osaka more than anyone. Affectionately known as "Odasaku," he had a friendly and bright personality that was open to everyone. He loved the resilient way of life of the common people and was a modern boy who walked the streets of Osaka in flashy clothes. On the other hand, he was extremely firm regarding literature, violently reacting to wartime national policies and sugar-coated literature, holding strong pride as a member of the Decadent School (Buraiha) who depicted the true intentions and grittiness of human beings. He was also extremely lonely, looking up to Osamu Dazai like an older brother, and had a passionate side, burning with rivalry not to lose to the literary masters of Tokyo. Despite suffering from tuberculosis, he lived through his short 33 years with life-threatening stoicism, continuing to write all night while injecting Philopon.

Ango Sakaguchi's personality is that of a "super-stoic genius where wildness and delicacy coexist." His private life was completely self-destructive. He didn't care if his room became a mountain of trash, and he led a grueling life of writing without sleep or rest while consuming large amounts of sleeping pills and stimulants, continuing to shave away his life by taking dozens of Philopon tablets at once. While he had the magnanimity to brush off being insulted by Chuuya Nakahara until morning at a drinking party, he also had a heart of glass that was hurt more than others by the evaluations and criticisms of others. He active as a member of the "Buraiha" who disliked existing morals and advocated for the necessity of human truth and decadence, but at his core, there was a seriousness and deep loneliness that sought truth more purely than anyone and dedicated his life to literature.

Ryunosuke Akutagawa's personality is that of an intellectual, refined, "extremely nervous and overly kind perfectionist." In his private life, he was a man of virtue who was gentle, personable, and admired by many friends and students. However, internally, he possessed a surprisingly delicate "heart of glass." He was excessively self-conscious, fearing the criticism and gaze of others, and could not escape the pressure of supporting a large family including his aunt and wife alone, always harboring strong anxiety. He was a super-stoic perfectionist regarding literature, and as a result of continuing meticulous creation that did not allow for a single character of compromise, he exhausted his mind and body, falling into nervous breakdown and insomnia. In the end, he took his own life at the young age of 35, leaving behind the words "vague anxiety." Behind his cold intellect, he was a person more easily hurt than anyone.

Kan Kikuchi's personality is that of a "don of the literary world and the most compassionate boss-figure in Japan," full of vigor and tolerance. He looked rugged and was socially awkward, but he was very caring; if there was a writer in trouble, he would unhesitatingly share his own manuscript fees. His selfless spirit can be seen in his founding of the Akutagawa and Naoki Prizes and his launching of many young writers into the world. While he loved gambling and enjoyed mahjong and horse racing, he also had excellent business sense and the realistic toughness to develop the Bungeishunju publishing house. He wept bitterly at the suicide of his close friend Ryunosuke Akutagawa and cherished his friends throughout his life. Although quick-tempered, he did not hold grudges, and his big-hearted, human personality led him to be deeply admired by the writers of the time like a father.

Takiji Kobayashi's personality is that of an "indomitable hot-blooded man and a surprisingly kind-hearted idealist" burning with a strong sense of justice and mission. Because he fought against social injustice as a standard-bearer of proletarian literature and met a gruesome end, being tortured to death by the Special Higher Police at the age of 29, he is often thought of as a cold revolutionary. However, his true face was that of a very compassionate and bright person who never forgot humor. During his time as a bank clerk, he was serious and admired by his superiors and colleagues, and out of a kindness that couldn't leave people suffering in poverty alone, he continued to help the poor and workers by spending his own wealth. Regardless of the danger to himself, his way of life—continuing to hold his pen while believing in a "better society of the future" even during a harsh underground life—contained a deep love and passion for humanity that embraced even the cold reality.
