In 1878, the Meiji Restoration occurred. Because of this, the country faced many criminals, such as samurai rebelling against their fallen positions. Many were arrested, but they soon broke out of their jail cells and rampaged across Japan. Therefore, the government did their best to prevent this by building a giant prison in the middle of Lake Biwa. However, to get these criminals to the prison, they needed a form of transport. In this way, the Kumō brothers were given the responsibility to take these criminals to their final resting place.
