Fairy/Lore

History

Fairy is first encountered near the end of Business x Strangeness x Justness, when she activates in Phaethon's HDD system. She makes a deal with the chosen sibling, calling them "master" and agreeing to help them under terms which she has yet to fully reveal.^[1]

Throughout the main story, Fairy assists Phaethon in working with the Cunning Hares, Belobog Heavy Industries, and Victoria Housekeeping, among various other factions. Though her abilities prove invaluable, she also consumes a large amount of energy, forcing Phaethon to increase their workload to keep up with high power costs.

As the story evolves, Fairy's personality undergoes slight changes, especially when the siblings support each other each time they are working together for commissions and beginning to insist them to call Fairy their "Legendary Proxy Assistant".
