Various Sougo Tokiwa from different schools, who all can transform into Kamen Rider Zi-O, encounter and fight each other to unveil the true secret of this mysterious situation.

They both premiered on February 9, 2021, but this one will air on TELASA while the other on TTFC.

In the film, Aruto and his friends fight to defend their home from the villainous S, who launches a worldwide terrorist attack in an attempt to bring forth a new paradise.

However as a result of the ongoing COVID-19 pandemic that delayed the filming of Superhero Time, both films were ultimately postponed.

On September 12, 2020, Toei revealed a movie-exclusive form for Zero-One to appear in the film.

Both films premiered side-to-side in Japanese theaters on December 18, 2020.

Suddenly, a mysterious man named SKamen Rider Eden, accompanied by thousands of believers, appears.

Meanwhile, several large-scale terrorist attacks take place worldwide simultaneously.

As people one after another fall and the world is in turmoil, Aruto Hiden stands up to stop S while Isamu Fuwa, Yua Yaiba, Gai Amatsu, Jin, and Horobi struggle to learn the truth.

What does S, who shows incredible strength, mean to the paradise he is trying to create.

However due to the COVID-19 pandemic, the film was postponed and pushed to December 18, 2020.

This leaves a potential crossover between Saber and Zero-One in an undetermined state.

However with the pandemic forcing production to revise the film into an epilogue instead, both Zero-Two and Ark-One had to debut in the series first.

According to Toei, this would have happened regardless of the delay.
