Celestial Realm

The Celestial Realm is one of the three worlds that exist in the game. It's the home of angels such as Simeon and Luke, and the former home of the demon brothers prior to their fall from grace following the Great Celestial War.

During Lesson 23, Solomon and MC went with Simeon and Luke to visit the Celestial Realm briefly.

Little is known about the realm but Luke stated that it was constantly daylight all the time (even during the night), which is the polar opposite of Devildom where it is dark all the time.

It's currently unknown who rules over the realm.
