Tenryu-kai

A mafia organization that controls the underworld of the Kanto region. They do not engage in dark dealings like drug trafficking or human trafficking; rather, they exist to crack down on those crimes and maintain order. The head of the organization is Guest's father, Gouki Amatsuka. Narumi was picked up by Gouki as a child and has belonged to the Tenryu-kai ever since. Guest is being raised carefully as the heir to the Tenryu-kai. The Tenryu-kai owns a vast estate, and within those grounds stands a grand Japanese-style house with a tiled roof. That is the headquarters of the Tenryu-kai. They also have branches in various regions and prefectures.
