The Daidaimaru (大橙丸 lit. "Great Orange Circle") is the Armored Rider Arms Weapon granted either by accessing Orange Arms or via the summoning ability of Kiwami Arms. It is a sword with the blade looking like a slice of an orange. It is also granted by accessing Type Fruits (in the case of Drive), activating the Kourin Signal Kudamono (in the case of Mach and Chaser), via the Shift Fruits Car, accessing Gaim Damashii via the Gaim Ghost Eyecon and accessing Gaim Gamer via the Toukenden Gaim Rider Gashat.


A Daidaimaru consists of the following parts:

  • Kahi no Jin (カヒノジン Kahi no Jin) is a special blade that acts on the chemical bonding of materials using the enormous energy generated by power cells. It is possible to produce cutting forces that can not be realized with normal swords.
  • Orange Power Cell (オレンジパワーセル Orenji Pawā Seru) is the power cell for energy supply embedded in the Daidaimaru's orange-pulp like parts. By keeping the power cell in a relatively large blade portion, the sharpness of the blade is maintained.
  • Odachinomine (オオダチノミネ Oodachinomine) is the back of Daidaimaru. It plays the role of a frame to hold the orange power cell and corresponds to the bone forming the blade.
  • Lock Gakka (ロクガクカ Roku Gakuka) is the green hand-guard of Daidaimaru.
  • Yatsukanonitogiri (ヤツカノニギリ Yatsukanonitogiri) is the handle of Daidaimaru.
  • Arms Coupler (アームズカップラー Āmuzu Kappurā) is the concatenation unit for connecting with Musou Saber. Merging the energy generated from the power cell of Daidaimaru into Musou Saber.

Known Users


The Daidaimaru can combine with the Musou Saber for the more powerful Naginata Mode (ナギナタモード Naginata Mōdo).[1] Naginata Mode can also combine with the Hinawadaidai-DJ-Ju to create the stronger Sojinto Mode (双刃刀モード Sōjintō Mōdo, lit."Double-Blade Sword Mode"), though this was never shown on-screen and thus is exclusive to the toyline.
