"Splendid... that was such delightful entertainment."
―Katchu Ganma's final words[src]

The Katchu Gamma (甲冑眼魔 Katchū Ganma, lit. "Armor Eye Devil") is a Gamma which achieved evolution through a broadsword and scabbard.


  • Object infusion: European Broadsword
  • Eyecon Target: All of Ghost's Heroic Eyecons
  • Destroyed by: Ghost Toucon Boost Damashii's Boost Omega Drive with the Sunglasseslasher in Sword Mode.


"It is violation to the code of chivalry by involving woman and children in battle."
―Katchu Gamma[src]

Unlike all Superior Gamma and almost like the Gazai Gamma, Katchu has her own way in living. She lives only to fight as an honorable knight and refuses to hurt weaklings who are not her target, especially women and kids. Her pride as a knight was also shown after she was freed from Igor's brainwashing to use any means to obtain Heroic Eyecons by returning the captured human's souls in exchange of Heroic Eyecons (which Igor's deal to be broken since the beginning) and left the battle field, telling Takeru that she swore a fair fight on their next battle.



Gamma Eyecon

Katchu Gamma's Eyecon, along with an broadsword

The Gamma are created from the Gamma Eyecons (ガンマアイコン Ganma Aikon), and one was merged with an broadsword to create the Katchu Gamma.

Gamma Assault

The Gamma Assault (眼魔アサルト Ganma Asaruto, lit. "Eye Devil Assaut") are Gamma born from the Gamma Eyecon. They first appear in Primal Body (素体 Moto-tai). Gamma Assaults do not possess unique abilities of their own, but can gain powers of their own through being infused with an object around them.

Powers and Abilities
A Gamma's primary ability is to turn themselves invisible and intangible to the public. Those whom wielded an Eyecon are capable of witnessing them.
Gamma can infuse themselves with ordinary objects, converting said object into a Parka Ghost, to achieve a unique evolved form. Should the Gamma be defeated, the object will be restored to its original form as the Gamma is destroyed.

Katchu Gamma

Through bonding with a European broadsword, the originally generic Gamma evolved into the Empowered Gamma (強化眼魔 Kyōka Ganma, lit."Empowered Eye Devil") known as Armor.

Powers and Abilities
A Gamma's primary ability is to turn themselves invisible and intangible to the public. Those whom wielded an Eyecon are capable of witnessing them.
Eyecon/Parka Infusion
Gamma Assaults can infuse themselves with Ghost Eyecons or at the very least, their Parka Ghosts to become Giant Gamma.
Schreiber (シュライバー Shuraibā)
The personal sword of the Katchu Gamma. As well as combat, she uses it to strike humans down in order to acquire their souls while in her brainwashed state.
Human Soul Container
Having been brainwashed by Igor, the Katchu Gamma is lent his spherical container which is tied to her neck, allowing her to absorb and contain the human souls she acquires.

Sounds for a hypothetical Katchu Gamma Eyecon are programmed into the Proto Mega Ulorder.

Behind the Scenes


Katchu Gamma is voiced by Naoko Kouda (幸田 直子 Kōda Naoko), who previously voiced Shroud/Fumine Sonozaki in Kamen Rider W. Its suit actor is Minoru Watanabe.

Concept Art

Katchu Gamma was designed by Kazuhiko Shimamoto (島本 和彦 Shimamoto Kazuhiko).


  • Katchu Gamma's ability to rob her victims by setting them on fire is a reference to her historical figure motif in real life, Joan of Arc, who lost her life after she was burned at the stake in 1431 due to being labelled guilty for several charges before she was proven innocent in 1456, 25 years after her death.
  • Her clothing and color scheme notably resembles Saber, one of the heroines of Fate/stay night and its related series. Ironically, while Katchu has her own doubts and instincts in combat, Saber on the other hand is strictly loyal to whoever she serves.
