Designated "SB-913X", the Kaixa Blaygun (カイザブレイガン Kaiza Bureigan) is a multipurpose weapon, serving as a pistol, a dagger and a lightsaber. By default, it is in the shape of the Greek letter Chi "Χ", or an upside down "4". In Gun Mode (ガンモード Gan Mōdo), activated by pulling on the Blaygun's hammer, it can fire 12 rounds of Photon Blood before it needs to reload. It is important to notice that the blade of the Kaixa Blaygun does not cause damage by itself, but due to the energy that it discharges once in contact with the target.
