Kamen Rider: Spirits of Nature and Fallen Souls

(The protagonists grow stronger over time + an ensemble cast + battles/ideals/passion/romance)

By forming a contract with a spirit of nature, a person can become a Kamen Rider and gain the power to fight monsters. The Hero Association has reached agreements with most spirits of nature. The Association sets various brutal “contract trials” to select worthy candidates, allowing the spirits to contract with them directly. Some other spirits of nature, however, choose to seek out candidates freely.

Yet behind this seemingly clear-cut picture lie secrets about where the monsters come from; secrets within the Hero Association; delicate relationships among the Association's departments; the mystery of the spirits of nature; another unfathomable power of contracts; and the fear, weakness, old grudges, self-interest, betrayal, revenge, and more faced by those who want to become heroes or have no choice but to become heroes. Where will it all lead? What does it mean to be a true “hero”? What choices will people caught up in this extraordinary age make?

Growing amid adversity, blooming in the cracks.

Between the rocks, laughter outlasts sorrow.

In the end, they will descend and kick across all eight wastelands!
