Kamen Rider: Beyond Generations (2021) Spoiler-Free Summary – What It's About

In a world reshaped by a century‑long legacy of masked heroes, the shadows that once threatened humanity have never fully receded. The era is a blend of neon‑lit streets and lingering ruins, where the memory of the original Kamen Rider still whispers through technology and myth. A lingering darkness, hinted at only by the name of a powerful Devil, hangs over this future, its roots tangled with the infamous Shocker organization that once sought to dominate the world.

Ikki Igarashi stands at the forefront of the new generation, a Rider whose experience is matched only by his restless drive to protect the fragile peace that remains. Beside him, Touma Kamiyama brings a cool, measured resolve, his own history intertwined with the legendary lineage of Riders. Their bond, forged through countless battles and shared purpose, creates a partnership that balances impulsive courage with strategic calm. Together they navigate a society that respects the past yet is haunted by the unknown threats that linger on the horizon.

Enter Ryunosuke Momose, a Kamen Rider who arrives from a distant future, bearing the weight of a personal quest as much as the collective one. His journey is as much about confronting the passage of time as it is about confronting the looming Devil; he seeks to bridge the gap with his now‑elderly son, whose memory holds the key to both redemption and resolution. As Ryunosuke’s presence intertwines with Ikki and Touma’s efforts, the trio must grapple with the eerie echo of Shocker’s legacy while forging a path forward for a world that still clings to hope.
