Gamma Assault

The Gamma Assault (眼魔アサルト Ganma Asaruto, lit. "Eye Devil Assaut") are Ganma born from the Ganma 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.

Younger Sohei Ganma

Through bonding with a yet-to-be revealed object, the originally generic Gamma evolved into the Empowered Gamma (強化眼魔 Kyōka Ganma, lit."Empowered Eye Devil") known as Sohei (Ototo).

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.
