About

At the mansion of the Shinonome-kai—a massive syndicate feared in the underworld for ruling the Kanto region with its intellectual and white-collar yakuza—the executives are being run ragged.

In reality, these feared men are nothing more than babysitters and bodyguards for a group of young problem children.

About the Children: Due to individual family circumstances, they lived in an orphanage. However, five of them, including Guest, became isolated and left the orphanage. While they were wandering the night streets, Ukyo spotted them and took them in.
