"I will stop you, even if it means laying down my life!"

Hiromi Kadota (門田 ヒロミ, Kadota Hiromi) is a Squad Leader of Fenix who due to his reckless actions, accidentally created the Rex Deadman and gave the Deadmans an advantage in their attack on the organization. As such, he became Kamen Rider Demons (仮面ライダーデモンズ, Kamen Rider Demonzu) out of an innate responsibility to stop Kamen Rider Evil.


Hiromi Kadota is a member of Fenix and a commander of his own squad. He was stated at a Fenix Research Laboratory where the Deadmans raided the facility and took a majority of the Proto Vistamps.

Hiromi after accidentally creating the Rex Deadman

During his Fenix commencement ceremony, the Deadmans launched a big assault on Fenix to which Hiromi and his squad proceed to combat the Giff Juniors and try to protect the civilians as they evacuated. He tried to take the Revice Driver and Rex Vistamp to transform, despite the protests by George Karizaki that he won't tame his inner demon. Instead, Hiromi manifested the Rex Deadman and caused the situation with the Deadmans to turn worse. Witnessing Hiromi failing to use the Revice Driver caused Daiji Igarashi to doubt and hesitate to use the belt himself, resulting in Ikki Igarashi successfully using the Revice Driver to become Kamen Rider Revi.

The next day, Hiromi opposed to his superior, Yujiro Wakabayashi, with the idea of letting Ikki using the Revice Driver. Because he refused to admit his blunders, Wakabayashi silenced him and Hiromi was relieved from his position of commander and demoted to captain after causing multiple mistakes. He was also harshly criticized by George Karizaki, who supported his demotion.

However, despite receiving such treatment, it didn't falter Hiromi's sense of justice as he bravely fought on the frontlines against the Deadmans as a squad leader, and remained focused on the mission. He would continue to lead his troops against the Megalodon Deadman and the Kong Deadman Phase 2, both were defeated by Kamen Rider Revi and Kamen Rider Vice.

One night while contemplating his demotion, Hiromi continued on and ambled in the Fenix base. Suddenly, an unknown Fenix captain broke into the vault and snatched the Lion Vistamp. After Revice managed to subdue the Lion Deadman and claim the Vistamp, they returned it back to Fenix where Daiji suggested to draw out the traitor. With Ikki Igarashi agreeing to join in their stakeout, Fenix stood outside the warehouse while Revice fought against the Deadmans generals. While Hiromi led his squad on standby await to make their move, he gets distracted by one of his troops tripping over debris. He and his squad get suddenly ambushed by Kamen Rider Evil and Hiromi is knocked out to the floor.

Hiromi as he begins to transform into Demons for the first time.

A couple of days later, Hiromi had grown suspicious towards Daiji over his sleeping episodes and odd demeanor. His suspicions were correct once he learned from Wakabayashi and George confirmed that Daiji was the one who apparently stole the two Vistamps. Deciding that he must put a stop to Daiji, Wakabayashi and George authorized Hiromi to use the Demons Driver, along with a Spider and Batta Vistamp. Hiromi would later arrive to Revice's battle against the Cheetah Deadman and Kamen Rider Evil. After delievering the Jackal Vistamp to Ikki, he personally held off Evil by transforming into Kamen Rider Demons for the first time. Demons managed to overwhelm Evil in battle, but the mysterious Rider managed to make a hasty retreat.


Hiromi is a determined and serious member of Fenix who's dedicated to protect people. Although his sense of justice is genuine, Hiromi can be prone to making mistakes and reckless choices. This led him to be demoted from commander back to captain status over his failures to prevent the Vistamp raid and accidentally creating the Rex Deadman. Despite these setbacks, he was nevertheless willing to comply to his superiors and continues to cooperate with Ikki Igarashi in stopping the Deadmans.
