This article is about a/an monster in Kamen Rider Zero-One.
For the character in Kamen Rider Amazons, see Mamoru (Amazons).

Mamoru (マモル Mamoru) is a Security Guard-Type HumaGear that was hacked by Jin and given a Zetsumerisekey to transform into the Ekal Magia (エカルマギア Ekaru Magia)[1].

After the Ekal Magia was destroyed, a new in-training model resembling Mamoru took his place, even donning the bandage Aruto placed on Mamoru's arm.


When Aruto and Izu arrive in Hiden Intelligence HQ, they were halted by a security HumaGear. Upon discovering that Aruto is the new CEO, the security HumaGear backed off. When the Kuehne Magia enters the building and is wrecking havoc inside, the security Humagear attempted to protect the civilians inside.

After Aruto fought Kuehne and returned back to the HQ, he searched for security HumaGear who protected the civilians before and learning his name as Mamoru, Aruto tells him to search for maintenance as his body is wrecked by Kuehne Magia. But unbeknownst to them, Jin watches them and then corrupts Mamoru.

When Jin in Hiden Intelligence, he arrives with Mamoru and introduces himself as a member of He commands Mamoru to kill Aruto, transforming him to Ekal Magia. Izu explains that a corrupted Humagear cannot be restored to normal, thus Aruto must destroy Mamoru.

Aruto transforms into Zero-One and he begins to fight Ekal Magia. Zero-One overwhelms the Magia, until he decides to escape using a hacked motorcycle and Zero-One goes after the Magia outside with his new bike. He successfully throws Ekal Magia from the bike, and they continue the fight in an empty dock. Zero-One defeats Ekal Magia using Rising Kaban Strash.

The next day, a new model resembling Mamoru is installed in Hiden Intelligence and appears in the press conference held by Hiden Intelligence.

Later, he was seen remembering Aruto as he scan his HumaGear Body Seal barcode with his own Progrisekey to help Izu Transfer his Data to Progrise Hopper Blade.It's Our Turn

Behind the Scenes


Mamoru is portrayed by Goro Yoshida (吉田 悟郎 Gorō Yoshida), who previously portrayed Toma Okajima in Kamen Rider Drive.


The Ekal Magia's name is derived from Ekaltadeta, an extinct genus of marsupial mammals that lived from the Late Oligocene epoch to the Miocene epoch.


  • Mamoru's name is derived form the word "mamoru" (守る "protect"), referencing that he is a Security-Type HumaGear.
  • The new HumaGear resembling Mamoru after his death sports the Shoshinsha Mark on his ear-pieces, a drivers' symbol in Japan that indicates beginners status for new drivers.
