World of Gamma

The World of Ganma (眼魔の世界) is the dimension where the Ganma reside in the form of Eyecons, passing through to the human world through Ganma Holes and taking humanoid form.

The monolith also serves as a gateway to the Ganma's world. It was through the monolith that Makoto Fukami was sent to the Ganma world as a child alongside his younger sister Kanon in 2005. While Makoto had evidently remained intact, Kanon was left reduced in the form of a Ganma Eyecon as Makoto became Kamen Rider Specter, fighting to claim the 15 Ghost Eyecons and restore her. Chikara Saionji, encountering Makoto as a young man 10 years later, spoke to him of the incident, implying that it was a result of Ryu Tenkuji's experiment in studying the Ganma. Meeting him again, Saionji later elaborated, claiming that Ryu Tenkuji, as the Ghost Hunter project leader, wanted to perform an experiment to see if a human could enter the Ganma world. Saionji went on to claim that while he and the other members of the team opposed his idea of human experimentation, Tenkuji had activated the monolith without their knowledge.
