Supposedly Real Past
Angie Yonaga was a normal talentless high school girl who participated in the 53rd Season of Danganronpa, a famous worldwide reality show made by Team Danganronpa.
She used to attend All Kinds of Stuff High School (ナンデモカンデモ高校). However, it is unclear if this memory of her is a part of the fabrication made by Team Danganronpa or if it was genuine.

Fabricated past
After she successfully participated in the 53rd Killing Game, Angie's memories and past were fabricated by Team Danganronpa as follows:
Angie originates from an island in the center of the ocean where people worship Atua, the God of the Island. The island is described as a paradise. It used to be large, but natural disasters made it smaller. It is overflowing with nature, though some plants are known to attack people, as a result, they are unsure if they even are plants. The locals also have lots of unusual customs, some of them quite unsettling. Notably, they give non-fatal blood sacrifices for their god using human blood, with a sacrifice truck coming around on Mondays and Wednesdays. The locals also use a mail order website called DeepSea to order things like her favorite magazines, food, clothes, medicine, organ meat, blood, and even children. Apparently, this website has improved the everyday lives of the island inhabitants significantly.
While living on the island, Angie was for some reason convinced that she was an oracle receiving divine messages from Atua. She began to control the whole island this way, using Atua's word to make other people do things for her since it was strongly forbidden to go against Atua's word. However, it's heavily implied that most of it was simply Angie's own wishes, but she was unable to tell the difference and assumed they were orders from Atua. It's implied that she suffered from loneliness, and sometimes ordered people to have big festivals.
