Summary
Ryu Terui explains to George Karizaki that he was fighting a Dopant, but once he finished the monster off, a mysterious stamp appeared by the side of its unconscious user instead of a Gaia Memory. Upon answering a phone call, Ryu takes George along to find another mysterious stamp.Meanwhile, at Suzu's lodge, Genpachiro Otta questions the remaining suspects about their activities at the time of the murder. Yasuo claims that he was reading emails and Naoto was trying to figure out why his television set was not working. As Genpachiro begins to get accusatory, Ikki explains that there was some sand at the murder scene. The cop then finds a vial of sand at Yasuo's side and accuses the restaurant worker, who claims he got the vial elsewhere. As the two argue, Ikki tries to break up the fight and remind both men of their main focus: to solve the mystery.
As Vice introduces himself to Genpachiro, Hiromi remembers that the Deadman they fought earlier could manipulate sand, when Suzu shows up to bring snacks to the young "detectives". As Hiromi and Genpachiro enjoy tea, Ikki asks them to find Suzu, whom they find learning guitar from Naoto. Suzu notices Ikki, who helps her with washing the dishes, during which, she reveals she inherited the lodge from her deceased father while Hiromi overhears her conversation with Ikki nearby.
Meanwhile, in Zawame City, George and Ryu find Kamen Riders Bravo and Gridon fighting an Inves, but upon defeating it, they see another stamp appear by its unconscious user, instead of a Lockseed. George is hyped to meet Oren Pierre Alfonzo and Hideyasu Jonouchi, as are the two Beat Riders, who explain that the stamp caused many Inves to appear recently. With the new stamp in hand, Ryu deduces that the stamp was capable of summoning different monsters other than Deadmans. George suddenly gets an idea of who could be making such stamps...
Back at the lodge, Ikki and Genpachiro discuss Suzu and the appearance of a Roidmude when a scream is heard. That scream came from Suzu, who was going to talk to Hiromi when a Roidmude tried to attack her. Hiromi transforms into Kamen Rider Demons to fight the Roidmude and save Suzu, but while the monster is defeated, the battle leaves Hiromi heavily injured...
Tropes
- The Knights Who Say "Squee!": George is overjoyed to see Oren and Hideyasu as Kamen Riders fighting an Inves. Once the battle's done, he runs up to them and they also hyped as the man.
- Percussive Maintenance: Naoto tried hitting his television screen with his palm to get it to work when the murder happened. Nothing happened.
- Single-Stroke Battle: Hiromi ends his battle with the Roidmude by charging towards it, intending to deal a finishing blow. The Roidmude does the same. Hiromi wins, but the monster's attack also leaves the man injured.
