Yasashii Washi JJ summary:
One day, a Japanese boy who wanted to be a policeman came to a border town in the hinterland of Brazil. In fact, this boy was dispatched from the extrajudicial organization "JJ" to save Japanese suffering overseas. Oil was discovered in Himanas, which became an independent country in the border area, and a civil war broke out over its interests, threatening the lives of the Japanese who migrated to this area. The 10 people secretly dispatched from the JJ organization were not informed of their faces or names, and the only clue was that they had a common testimony!
