Secret Kings is a secret organization in China, exclusive to the State Secrets Bureau.
It mainly investigates special events across the country, and the task level is top secret.
"There are many things in this world that cannot be explained by science." Is their mantra.
Secret Kings is only a code name used for international communication, and members of the group prefer to call themselves "Group K".
It has four branches: Beijing, Shanghai, Chengdu and Lhasa.
Above the four there is a "Conference of Five Kings".
It is composed of the four leaders, the Dragon Master of Chengdu, the Fire Emperor of Shanghai, the Bird Official of Lhasa, the Human Emperor of Beijing and the "Secret King".
