Times are a-changing in MegaTokyo. Boomers are no longer seen as a scourge, but rather, the city’s saviors - heralds of a new, prosperous era. With the Knight Sabers' mission supposedly accomplished, their leader, Sylia, suddenly disappears, leaving the team to go their separate ways. In the meantime, a dangerous cabal of power-suited mercenaries start hunting for a revolutionary AI that’s about to change the world. Keenly aware of the consequences, Sylia gets the band back together. Equipped with even bigger and badder hard suits, the Knight Sabers now find themselves entangled in a conflict seemingly orchestrated by a voice from the past.
