The Shinjin (芯人 Shin-jin, literal meaning "Core People") are a race of beings from Kaishin. The Shinjin are the true race all Kai and Supreme Kai come from before being given their respective role. Their planet holds roughly a population of 80 Shinjin at one time.
The Shinjin are born from magical fruits that grow off of the Kaiju. The average Shinjin possesses special abilities that far surpass that of any sort of un-trained normal being. Shinjin live leisurely lives, studying various things at a school-like castle. The Shinjin lifespan is roughly 75,000 years, however those born from golden magical fruits can live for several millions of years.
Whenever one of the Kai on the Kai planets passes away, the Shinjin 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 Shinjin born from a special golden fruit that is particularly rare.
Most Supreme Kai have the same general appearance: tall and thin with white mohawks and sharply pointed ears, generally only differing in skin color and other minor details, though there are exceptions, particularly in the case of Universe Seven.
Occasionally, there are Shinjin who are born evil. Those delinquent Shinjin are cast into the Demon Realm ruled by the Makaioshin, where they live with the Makaio and are secluded from civilizations.
