The Heavenly Realm (신계 (神界), Shingye; lit. "Divine World") is one of the three known realms in the God of High School world. It is populated by various gods. It is the most powerful realm, followed by the Sage Realm then the Human Realm. Nearly a thousand years ago, the Heavenly Realm and the Sage Realm had a great war which ended with the Sage Realm losing and the Heavenly Realm coming out victorious.
The Heavenly Realm is home to many powerful gods of various mythologies and legends like the Jade Emperor and Michael the Archangel. It is revealed by Beelzebub that time flows much slower in this realm than the humans', as he mentioned that Jade Emperor wouldn't be so old if he stayed in this realm.
Due to the contracts between the three realms after RagnarÖk, Heavenly Realm can't meddle in business of other realms. It is enforced by a system similar to taboo they imposed on human beings.

The Heavenly Realm is a tower located inside a planet with its surface covered with toys. It is made up of 10,000 floors built into a planet with each floor progressively harder to conquer than the one before.
The last seven floors is the main sub-realms of the heavenly realm. These seven floors are ruled by what the natives of the tower call the Owners of the World, better known as Masters of the Heavenly Realms by the Gods. The Gatekeeper guards the entrance to the 7th floor to make sure only those that are worthy make it through. In order to proceed from one floor or realm to the next, the intruder must defeat the ruler.
Below is the information about each sub-realms.

Angels & NephilimThe angels are the foot soldiers of the Heavenly Realm and the nephilim are the commanders of the soldiers of the Heavenly Realm. One nephilim is easily capable of wiping out an island. The humans are incapable of actually attacking the nephilim ranked gods and higher due to the seals placed on the Human Realm, however the inhabitants of the Sage Realm are capable of attacking the nephilim. Michael the Archangel appears to be their overall commander, as shown when he ordered a division of them to rain down spears on the unsuspecting humans below.
