Season 1

Outside, a book stand selling copies of Kotarō's book is seen. Inside, an office worker (Natsumi Miwa) is refused a promotion by her boss and resigns. Later, while out walking, Natsumi is attacked by the Peacock Undead. Meanwhile, a mysterious figure watches the assault and starts to approach as the words "to be continued" flash across the screen.

At a resturant, a waiter (Shin Magaki) confronts a loud group of patrons and is fired. Later, while out walking, he bumps into a fleeing Natsumi, and both start running from the Undead. The mysterious figure continues following the group as the words "to be continued" flash across the screen.

Natsumi and Shin continue running from the Undead. Natsumi finds a steel pipe and tries to get Shin to cover her escape (claiming that men are supposed to protect women). This fails and the Undead continues chasing them until an explosion destroys it. The mysterious figure approaches them (no longer hiding) and throws them both Change Kerberos Rouze Cards. He then returns to human form as the words "to be continued" flash across the screen.

Junichi offers them both to be Kamen Riders. He also explains that the incident with the Undead ended once, but the power of the Kamen Riders is needed again. Natsumi and Shin refuse and give back the cards. Junichi says to himself that they will return, and that it is their fate is to become Riders. Behind Junichi is Kazuma Kenzaki, who becomes a garbageman. Natsumi and Shin walk away (with images of their rider forms being shown) as the words "to be continued" flash across the screen.
