The term Kishin may refer to:
- A being (also called an "Afreet") in which is the result of the overhunting of innocent, human souls.
- Asura, the first generation Kishin whom is also synonymous with "Kishin" due to being one.
- An Evil Human or an individual who is a Kishin Egg (or Afreet Egg). This term is actually used INCORRECTLY in this context, as those who are Kishin Eggs/Evil Humans are not actually Kishins; this notion was mentioned by Franken Stein in both Episode 7 and Chapter 5. This misconception originated due to mistranslation.
