In Zawame City, the Yggdrasil Corporation’s roots are everywhere. To escape from the corporation’s stifling presence, the dancing Beat Rider teams compete for street cred. But when Beat Riders start settling turf disputes using strange devices called Lockseeds, dimensional tears open across the city, unleashing the monstrous Inves. When ex-Beat Rider Kouta Kazuraba is caught up in an attack by a berserk Inves, he stumbles upon a high-tech device allowing him to transform into “Armored Rider Gaim” and defend his friends & the city.
