I'm Just a Passing Kamen Rider: Spirit's Infinite Journey

When a Shomagia awakens to something beyond programming, the line between machine and soul blurs forever. In a multiverse ravaged by spreading malice, Kamen Rider Spirit emerges—not to protect what's already lost, but to save the very essence of existence itself. From the blade-wielding heroes of Saber to the game-world battles of Ex-Aid, journey through infinite Kamen Rider universes where every world faces extinction and only one question matters: can a spirit without life still possess a heart worth saving?
