Abetti was a female and a presumed redpill. She was a former aquintance of Anome, and was said to have had some dealings with him. When Anome showed his true colours and became the mad leader of Unlimit, he began to kill any of his acquaintances, whether they were friends or enemies. The Machinist player was tasked to find her, find out from her any information, and possibly detain her. Unfortunately, the Machinist player was already too late, as the Unlimit soldiers found her first and were just about killed her. Despite defeating the Unlimit there, she inevitably died, but not before she tried to curse Anome's name.

Abetti was the last name of an astronomer father and son, of which they named a lunar crater after their last names.
