Fairy

Fairy is a sophisticated artificial intelligence program that specializes in Hollow exploration. It is one of the four "keys", together with fellow AIs Jinni, Ghost, and Youkai, though the significance of this role is yet to be revealed. Its current master is the Proxy Phaethon, Zenless Zone Zero's main character. 
== Profile ==
Fairy is first encountered in Chapter 00, "Fairy", when she activates in Phaethon's HDD system. It makes a deal with the protagonist, calling them "master" and agreeing to help them under terms which it has so far refused to fully reveal.
Throughout Chapters 1, 2, and 3, Fairy assists Phaethon in working with the Cunning Hares, Belobog Heavy Industries, and Victoria Housekeeping, among others. Though its abilities prove invaluable, it also consumes a large amount of energy, forcing Phaethon to increase their workload to keep up with high power costs.
=== Appearance ===
Fairy takes on the appearance of a blue eye resembling a nazar amulet. It speaks using a monotone female voice.
