Plot
Upon arriving in the World of Faiz and once more encountering the mysterious Daiki Kaito, Tsukasa finds himself in a school uniform and enrolled at Smart Brain High School. He learns that the high school is attacked on a nightly basis by beings called the Orphnoch, with only Faiz to protect the school. Daiki challenges Tsukasa to find out who Faiz is, and Tsukasa then challenges the Lucky Clover clique to a tennis match to see if any of them are Faiz. He beats them, learning that they are Orphnoch who are also after Faiz, and is forced to become Decade, using Blade's power against them. However, Decade is outclassed when Momose appears as the Tiger Orphnoch and warns him to back off. Daiki then confronts the group, giving them a hint as to who Faiz is before going off. Then, the Lucky Clover members target Yuri Tonoda and Takumi Ogami, believing Yuri is Faiz until Takumi transforms and fights them off. When Tsukasa learns that Yuri is the target, he goes off to fight the Orphnoch, watching Faiz get defeated and losing the belt. The fight is then interrupted by Daiki Kaito who transforms into Kamen Rider Diend while revealing he used the Lucky Clover to take the belt for himself. Once the Centipede Orphnoch is destroyed, Decade and Diend have a stand off over the Faiz Belt as Momose attacks Yuri as the Tiger Orphnoch only to meet his match with Takumi who transforms into the Wolf Orphnoch to protect his friend.
