"So this is the bond you were talking about? Hah! Laughable!"
―His words when mocking Kabuto and Gatack about Hiyori's safety[src]

Reiji Nogi (乃木 怜治, Nogi Reiji) was the human form of the Cassis Worm (カッシスワーム, Kasshisu Wāmu) who loves to cause annoyance to the Riders in Kamen Rider Kabuto.


Nogi is an even stronger Executive Worm, entering the scene after Uca Worm is destroyed. Reiji likes showing off his powers and taunting the Riders from time to time. He wants to attack and seize Area Z, to take the Masked Rider System for the Worms

Unlike the other Worms seen so far, Reiji is perfectly capable of fighting without transforming into its Worm form. In fact, Nogi is able to utterly overpower Kamen Rider Gatack while the former is still in his human form while the latter is transformed, only Tendo can rivaled him without transformed. His favoured fighting style in human form is rapid kicking and his weapon of choice is a cane.

He has the "Life of Immortality" ability, which enables him to evolve into a new form each time he gets defeated. Each of his forms has an exclusive natural fighting ability and a unique power of his own. Cassis Worm is easily one of the most powerful foes the Kabuto Riders have faced. In its first form, Hyper Kabuto is helpless before its time-stopping ability. His second form effortlessly defeats Gatack, TheBee, the Hopper brothers and Sasword. It takes a triple Rider Kick and a Maximum Hyper Cyclone to kill him in this form. He is eventually permanently destroyed in his third form, Cassis Worm Clipeus, by Kamen Rider Gatack and the Hopper Riders.
