The series is set in Tomioka's brightly colored yet worn and grubby surreal world, where, on this occasion, we see commuter trains packed with deep-sea divers reading pornography. Sealed off behind their protective shells from any real human contact, the commuters are clearly inspired by Tomioka's experiences on Tokyo's underground but perhaps represent everyone who shuts themselves away behind iPods, computers, and books, afraid of real face-to-face human interaction.
