Okiku and the World

About 150,000 illegal entrants live in Tokyo. They are not recognised as refugees and live in poor conditions. To protect themselves, the illegals create a secret organisation. The organisation has a bank which Japanese Financial Services Agency is not involved with, a hospital that is not authorized by Japanese Ministry of Health, Labour, and Welfare and an illegals police force called "Dias Police." The only police officer in the organisation is Saki Kubozuka (Shota Matsuda). His age and nationality is unknown. Saki Kubozuka does not speak much, but he has a warm heart and strong sense of justice. He takes care of the weak and tries to maintain public order.

Dias Police: Dirty Yellow Boys

Jun Wataguchi lives a lazy, half-hearted life, not going to school, hanging out with half-witted delinquents, and begging money from his friends. His parents, who run a shipping business transporting earth and sand for reclamation by boat, manage to get by, despite the dwindling number of jobs and lack of successors over time. Jun showed no interest in his parents' business, and the father and son hardly ever spoke to each other. One day, one of Jun's friends is attacked by someone and an unexpected person emerges as the culprit.
