The first chapter of Rainbow: Nisha Rokubou no Shichinin , "Seven Men in a Hellhouse," follows six teenagers arriving at the brutal Shōnan Special Reform School in 1955. There, they meet and bond with a seventh inmate, Rokurouta Sakuragi, amidst severe abuse from the facility's doctor and guards. For more details, visit

The Shared Cigarette: Joe, who had managed to stash a single cigarette, offers it to Sakuragi. Instead of taking it for himself, Sakuragi shares it with all six boys.

The chapter introduces six young delinquents—Mario Minakami, Noboru Maeda, Matsuura Ryuuji, Tadayoshi Tooyama, Mansaku Shigaraki, and Joe Yokosuka—as they arrive at the Shounan Special Reformatory School. 

• Inking: Kakizaki uses thick, heavy black inks. Shadows are deep, almost oppressive. The reform school feels like a yawning abyss.
• Faces: Every character looks worn. Deep wrinkles, hollow eyes, chapped lips. Even the teenagers look middle-aged from suffering.
• The singing panel: The layout shifts. The panels become wider, cleaner. The darkness recedes as the boys sing. Their faces are lit not by a light source, but by the emotion of hope. It is a masterclass in visual storytelling.
• Violence: Kakizaki does not shy away. When Sasaki hits a boy, you feel the crunch. The art is visceral, uncomfortable, and necessary for the story’s weight.

The Humiliation: Upon arrival, the boys are subjected to a dehumanizing medical examination by the sadistic Dr. Sasaki.
