Angel

An angel is a being that exists in the form of a spirit, able to transport themselves from one location to another. They are usually considered divine messengers from God, though there are also fallen angels that some Christians claim have become demons.

Canon Media
Although non-existent in present comic or film productions, angels typically reside in Heaven under Providence's jurisdiction and can be separated into two categories: original or human angels. Original angels are the beings created directly by Providence before creation of the Earth and all of humanity while human angels are the result of deceased humans earning a place in Heaven during their lifetime. So far, Wester has only revealed one concept angel character named Jojo, who may appear in future works.

Much like demons, angels retain their human appearance, although whether or not they retain fatal injuries is yet to be revealed. Original angels have not appeared either, but there is the notion by Wester that they tend to appear closer to human forms (perhaps in a more idealized manner than human angels). Also like demons, some individuals can be assigned to human counterparts acting as "guardian angels" for various reasons, but the process of becoming an official GA seems to be the human equivilant to obtaining a driver's license from the DMV.

In a previously pitched ending of the series, Jonathan would have become an angel after having been fatally hit by a bus; whether or not this will be officiated is yet to be revealed.

UC Stories
Within the Universal Clarification Series, the process of becoming a Guardian Angel are in sync with canon media, but with a slight twist. When a human arrives in Providence's office, she gives them three options to choose for their afterlife:
 * 1) Become an angel and reside in their unique version of paradise in Heaven.
 * 2) Petition to be reincarnated, which will result in virtually full-scale memory loss of any and all previous lives.
 * 3) Petition for a second chance at life (usually reserved for extreme cases, such as someone who has slipped away from a coma, but may still be revived).

Once an individual chooses one of those options, that becomes their permanent afterlife experience and Providence provides the best possible care for every soul's unique tastes. So far, Mephistopheles is the only angel she has the displeasure of banishing from Heaven.
