Trivia

 * While this list is a classification of races in YGGDRASIL, the New World inhabitants, specifically humans regard their cousin races: dwarves, elves, etc. as demi-humans.
 * In the English publication of the Light Novel, Demi-Human and Heteromorphic races were translated as Subhuman and Grotesque.
 * In YGGDRASIL, it was possible for a Player to change their race mid-way, but it didn't mean one could switch arbitrarily. One needed to fulfill several conditions and the change would be irreversible.
 * Humanoid and demihuman races could not produce offspring together. However, mating between humanoid races is possible according to the Elf King.
 * Contrary to the notion that procreation between a humanoid and demi-human was said to be impossible, in the Web Novel, there was a legend that spoke of a human princess who is impregnated with the Goblin King's child.
 * It is possible for humanoid races such as humans to interbreed with a heteromorphic race depending on the particular species they're doing with. For starters, the Brightness Dragon Lord is so far the only known dragon, one of the heteromorphic races to mate with a human among the humanoid races.
