Wielder of the Gate of Fire, Fei hails from the Chinese (Shanghai) branch of A.E.G.I.S., and joined the Japanese branch to help out with the high concentration of Invader activity. Her companion, a golden monkey called Ukiya (a licensed A.E.G.I.S. agent - but was once confused with Shun Ukiya), often helps her target Red Invaders. Her skills include "Da Xiong Mao" (Exploding Panda Fireball) and a fiery dragon (Shocking Fire Dragon).
