Dazai Osamu is a hero in the Bungou Stray Dogs anime. In other word he’s the main character.
Dazai mostly is the good guy in Bungou Stray Dogs but in the spinoff novel?Dazai and the Dark Era, he is the villain.
Dazai is an intelligent man but he is suicidal and he attempted suicide many times that everyone around him thinks he’s just joking.
But you know I seem to remember that this name, Dazai Osamu / Osamu Dazai belongs to someone historically important in Japan. A writer maybe?
Anyway Dazai anime paper craft requires only 4 sheets of paper to build.
