The Kyoryugers discover Dogold has been using Utsusemimaru, the Sengoku period's Kyoryu Gold, as his host. Repossessing Utsusemimaru, Dogold uses his host's signature Raiden Zankou attack to defeat the three Kyoryugers with Kyoryu Black uses a Parasagun/Ovirappoo Zyudenchi combo so they can escape him and Cambrima. Returning to the Spirit Base to heal, Torin reveals he and that he was mortally wounded ages ago and could kill himself if he strains himself further. While leaving Ian and Nobuharu to find a Zyudenchi suitable to deal with Pteragordon, Daigo goes to Genryu to develop a counter to Utsusemimaru's signature move via sword training. Elsewhere, after Utsusemimaru attempted to free them, Amy manages to free herself and Souji as they contact Daigo being before cornered by Cambrima as Aigallon, Canderrilla, and Luckyuro arrive with a second Cambrima. After arriving and using the Beyonsmo Zyudenchi on Gabutyra to ground Pteragordon, Kyoryu Red fights Dogold while the male members are holding off other Deboth members as Kyoryu Pink ran off. During the fight, Torin then holds Dogold as he projects his Spirit to have Kyoryu Red use it in the Pteragordon Zyudenchi in an attack that can free Utsusemimaru. However, having learned of Torin's condition from Utsusemimaru, Kyoryu Pink manages to get Kyoryu Cyan to offer a hand. Though Dogold unaffected by the attack at first as he enters Pteraiden-Oh, Utsusemimaru manages to break Dogold from the inside as Pteraiden-Oh is purified. With Zorima surrounding him as he emerges, Utsusemimaru transforms into Kyoryu Gold to defeat them. When the Cambrima are enlarged, Pteraiden-Oh destroys them. As the sun sets, finding Dogold's remains gone and recognizing Daigo as someone from his past, Utsusemimaru refuses to join him and walks off.
