The Enigmatic Belt (謎のベルト Nazo no Beruto) is the eleventh episode of Kamen Rider 555. This is the second episode of the Kaixa Gear arc.
Takumi is beginning to think that maybe he was meant to be Faiz.
We meet members of Lucky Clover for the first time. Chief Murakami ask Mr. J, a member of Lucky Clover, to take back the Faiz belt and get rid of Takumi. Murakami arranges for Takumi and Mari to be at the same amusement part that Keitaro has taken Yuka to. Takumi has a hard time fighting Mr. J in Orphenoch form. The new rider makes a brief appearance and fires on Mr. J at the end.
First appearance of Kamen Rider Kaixa.
Smart Lady gives the Snail Orphenoch one last chance to properly attack a human. Kaido shows Kiba and Yuka the Faiz Gear and tells them that they should think about what they're doing before he has to attack them too. Kiba goes to see Murakami about his plans. Yuka attacks three men as the Crane Orphenoch while Takumi becomes depressed over no longer being Faiz. Kaido later attacks Takumi on his bike but leaves when Murakami calls with a job for Faiz. The Snail Orphenoch finally makes a kill. Kaido and Kiba fight as Faiz and the Horse Orphenoch but Kaido is unable to deal the final blow allowing Kiba to defeat Faiz. Keitaro takes the Faiz Belt from Kaido but he is attacked by the Snail Orphenoch. Takumi saves him and transforms into Faiz and destroys the Orphenoch, watched by another Rider...
