Hideo Akaishi

* Fenix
* Deadmans

## Appearances

**Hideo Akaishi** (赤石 英雄, *Akaishi Hideo*) is the major antagonist of *Kamen Rider Revice*, Formerly a board member of NOAH, he became the director of Fenix while also secretly founding the Deadmans. His true motives lie with his desire to ensure the survival of humankind by halting human evolution and making them forever subservient to the demon he worships, Giff.

## History

### Background

Hideo Akaishi was born on August 26, 1964 and graduated from university in America, later going on to work for the Department of Defense and helped inaugurate a technical management plan for the Pentagon. He later returned to Japan and began working as a researcher for NOAH until its collapse in 1996. He founded Fenix and seized Giff's coffin for research, while also secretly founding the Deadmans on the side to reawaken Giff and advance humanity to another evolutionary state. He would be responsible for recruiting Makoto Hatsushiba into the Deadmans' ranks.

### The Fenix Conspiracy

Akaishi arrived on the Skybase after Fenix confiscated Giff's coffin following the destruction of the Deadman's base. He intervened after Hiromi Kadota proposed to destroy Giff's coffin, telling him that it would be a hasty decision since Fenix's priority was to locate Orteca, Aguilera and Julio. He later approached George Karizaki regarding the Demons Driver's status, which Akaishi is informed that it will be restored to its former state soon enough.

After Orteca was captured by Fenix, Akaishi went to speak to him under the pretense of an interrogation. When Orteca handed over the Giff Stamp, Hiromi caught them in the act and attempted to stop them. Suddenly, the Fenix Skybase suddenly veered off course, allowing Orteca to summon the Giff Juniors to attack Hiromi, while escaping with the Demons Driver. After Orteca defeated all the other Kamen Riders as Kamen Rider Demons, Akaishi stood by Giff's coffin as it increased with energy.

Sometime after Hiromi's disappearance, Daiji approched him regarding the former's search. Akaishi stated that Hiromi was expendable and to focus on pressing concerns. As Giff's revival was coming close, Akaishi warned Orteca to not succumb with hesitation. When Kagero threatened Karizaki demanding the Crow Vistamp, Akaishi permitted Karizaki to hand it to him as it would be another challenge for Daiji to overcome, and should he fail, Kagero could take his place.

Following Orteca's defeat against Holy Live, Akaishi congratulated him as Orteca's contributions will result in Giff's near revival. However, Orteca refused to become his underling as he sought to remake the world. Akaishi returned to Fenix Skybase to witness Giff's coffin absorbing the Fenix members, all according to his plan. Soon after Orteca was absorbed into Giff, Akaishi bowed before his master and declared that it was time for humanity to reach the next stage in evolution.

### Giff's Revival

In an effort to advance his plans, Akaishi came into contact with Vail and kidnapped Akemi Mikoshiba, who had spotted their cooperation. He managed to frighten Akemi to the point where she had lost hope for humanity and willingly became subservient to him.

## Personality

Hideo Akaishi is a manipulative man who views every human being to be nothing more than a disposable tool, and dismisses them without exception once they've served their purpose.

Despite his vocal approval whenever his subordinates (either Deadmans or Fenix) succeed with their plans, Akaishi is never seen as a credible threat by anyone who underestimates him. His charisma is dangerous enough to make Weekend members wary of approaching him. Even when those close to him know his true nature, Akaishi manages to prevent any attempt to stop him and disposes them, either directly or indirectly.

Different from Aguilera, who wants to get close with Giff out of love, and Orteca, who allies with Giff to obtain his power, Akaishi is completely servile to Giff, as his own mutation drives his desire to evolve humanity through Giff.

## Behind the Scenes

* Hideo Akaishi is portrayed by Jun Hashimoto (橋本 じゅん, *Hashimoto Jun*).

### Etymology

The characters that make up his first name can alternatively be read as "Eiyū", which means "hero" or "great man", befitting his status as Fenix's director. Ironically, Hideo is a villainous character rather than a heroic one.

## Notes

* Akaishi's outfit as the director of Fenix is a reference to Apollogeist's human form. This is because the designs of the villains of the series pay homage to the suits of classic *Kamen Rider* villains. This is fitting since Akaishi and Apollogeist are major villains of their respective series.
* While confronting Daiji in Episode 33, Akaishi recited the passage of Furinkazan, a battle standard used by the Sengoku period.
