Plot
The story is about a dying old woman (Amane) who tells her grandson the story of the 4 Kamen Riders. The story covered what happened to the 4 after Kenzaki went missing after his fight with Hajime.

Hajime lurks around Amane, and stayed by her side during her last moment. He looked exactly the same as they first met. Mutsuki Kamijo, Shiori Hirose, and Kotaro Shirai died due to old age. Kotaro's book about Kamen Rider was so popular that it later became a TV drama and merchandise, which made a lot of money for the Kurihara family.

Tachibana became the head of the BOARD. He kept on researching on the Undeads and did experiments on himself. He gained long longevity from his research and kept an eye on the 2 Jokers. He is also Amane's health insurance.

Tachibana found information about an unknown beast attacking armed insurgency in Africa. The beast was trying to keep homeless kids safe from the war zone. That beast is likely to be Kenzaki in his Joker form.
