As the Igarashis face an eviction notice and the potential loss of their sento due to city renovations, Daiji visits his hospitalized mother, Yukimi, for advice.
Ikki successfully rescues Sakura and Ayaka from a Deadman, only to learn their kidnapper is not in possession of the corresponding Vistamp, forcing him and Vice to find it before it causes more trouble.
To celebrate Yukimi being discharged from the hospital, the Igarashis take a trip to a hot spring resort. Upon arriving however, they learn that their regular customers, the Ushijima family, are also there.
After Sakura awakens her inner demon instead of becoming a Kamen Rider and Ikki is injured while protecting her, Daiji demands she hand over her Rider equipment to Fenix so they can investigate the person who sent them.
Fenix is forced to land their mobile headquarters, the Sky Base, in order to refuel, restock on supplies, and give several of their operatives, such as Kadota, time off.
Wakabayashi is suspected of being a traitor and the contract holder connected to the Chameleon Deadman. In spite of Daiji and Kadota's shock, Karizaki decides to set a trap for the Deadman to confirm.
A shocked Aguilera discovers she is intended to become a sacrifice for Giff's revival instead of his bride, which her right hand Orteca knew about and withheld from her while her bodyguard Julio becomes livid over the revelation.
Deadmans' attack has been thwarted, but Aguilera and Julio are on the run together while Orteca and the Chameleon Deadman move forward with their own plans.
