LIGHT:

Learn about Light demons in Shin Megami Tensei III: Nocturne HD Remaster. They are often gods, rarely join your party, but can be created via fusion.

Light demons are almost exclusively gods, often worshipped deities within their pantheons. However, in Shin Megami Tensei III: Nocturne HD Remaster, Light does not necessarily equate to good; for example, the Chimera is not considered good. You will rarely encounter Light demons, and when you do, they will not negotiate or join your party, especially as most encountered are bosses. They can, however, be created through demon fusion and tend to be more powerful than Neutral or Dark demons.
