Mechanika — Meg to her colleagues — is a ghost with a day job: she clocks in at Shorewater Industries, one of Nova City's corporations, making her the roster's strangest and most beloved reveal.
Her powers are industrial-scale animism: she brings machines to life, commands robots in combat, and stages full-scale mecha concerts — a phrase from official material that fans have been decoding ever since.
Mechanically she reads as ANANTA's summoner archetype: where Richie hits and Bansy saturates an area, Mechanika delegates — the fantasy of fighting through a workforce of possessed machinery.
A ghost on a corporate payroll is also a lore statement: Nova City's supernatural — the same Chaos that empowers Espers — is normalized enough to be employed. What Shorewater Industries builds, and why it hired her, are open questions the story is clearly saving.
She was revealed through official bios and character material rather than a public demo (timeline). Unknown: her progression profession, the limits of machine animation, and whether the mecha concerts are cutscene flavor or a playable system.
