Shin-jin (神人; lit. "God-People" or "Core-People") are a race of beings from Planet Kaishin. The Shin-jin are the true race all Kai and Kaioshin (Supreme Kais) come from before being given their respective role. Their planet holds roughly a population of 80 Shin-jin at one time.
The Shin-jins are born from magical fruits that grow off of the Kaiju trees. The average Shin-jin possesses special abilities that far surpass that of any sort of un-trained normal being. Shin-jins live leisurely lives, studying various things at a school-like castle. The lifespan of the basic Shin-jin is roughly 75,000 years, however the Shin-jin born from golden magical fruits can live for millions upon millions of years.
Whenever one of the Kai on the Kai planets passes away, the Shin-jins draw lots among themselves to choose who will take the Kai's place and become a new Kai. The Supreme Kais, however, are chosen only from among Shin-jins born from a special golden fruit that is particularly rare.

- During his appearance at the World Martial Arts Tournament in the Majin Buu story arc, the Supreme Kai uses the name "Shin" at the tournament, which is later established by Akira Toriyama to be the name of the original Kai race.
