Fei

After the official launch of Project FIELDS in 2020, Fei became the designated Guide of the New Exploration Department. Recognized by Salvagers as an excellent guide, she has thorough knowledge of various equipment and excels at organizing Reports. Though sometimes she enjoys doodling Graffiti on informal Documents, much to the Salvagers' amusement. Rumor has it some even collect her masterpieces on old Documents.

In 2012, during the testing of the New Helen Stabilizer, Fei passed the Stability Test and became the primary tester for the new equipment. She was highly familiar with the System, which was one of the reasons she was later selected as Guide. Fei's test period number was A, though few knew this. The earliest work number she remembered was Doctor's number 4, and she trusted Doctor completely.

An accident seemed to occur during the Test, causing Fei to lose her past memories. Starting anew with the name "Fei", she relearned the modern world and ultimately chose Behind the Scenes work providing Guidance as both a Salvager and governor module. Of course, being a Salvager herself, she also participates in frontline operations.

Asking Fei about the past won't yield answers, yet she doesn't evade the question herself. Fei's daily life resembles that of any ordinary girl—she has friends in the Exploration Department, long-time colleagues both senior and junior, and a trusted team leader. She's quite content with her current life. Due to differing work schedules between Guides and Salvagers, Fei rarely gets chances to go out with everyone. But within the Corporation's premises, her presence is often seen.
