Grand Kai is one of the highest authorities in Universe 7 for Dragon Ball. He's the king who directly overseers the 4 Kais, however he is still subservient to the 4 Supreme Kais and their overseer. Unlike many of the other Shin-Jin, he takes a far more casual and lighthearted approach to his position. Acting much like a grandfatherly figure rather than an authoritarian.
