Simeon is one of the two angels sent from the Celestial Realm to take part in the exchange program, and he is first introduced in Lesson 2-13 along with Luke. He is one of the main characters in Obey Me!

Simeon has a calm demeanor yet despite his generally kind nature, he is a very strict but good supervisor. He doesn't give Luke direct answers; instead, he prefers to give him opportunities to figure things out on his own. Simeon tends to look for compromises, even if not agreed with, and he tries to act as an interlocutor.
