Riku Kurita, a boy orphaned by the meteorite crash, lives his days in the slums under the watchful eye of Goro Fujimoto, a middle-aged police officer whom he adores as his uncle.

However, on July 8, in the 10th area of the slums, Fujimoto was killed while trying to expose the evil deeds of Eishu Kidoin, the police inspector general.

In order to defeat Kidouin and avenge his uncle's death, Riku decides to escape from prison with his friends.

After much effort, he gathers his friends and manages to escape from the prison of the Island, but the group falls into Kidoin's hands and is sent to Kidoin's illegal facility, Hell Island on Jigokujima, where huge mine shafts were dug underground, and opium was cultivated and manufactured above ground.
