Season 1 - Kamen Rider Ghost: Legendary! Rider Souls!

This series features the debut of six Legend Rider Damashii, namely Ghost's Drive Damashii, Gaim Damashii, Wizard Damashii & Specter's W Damashii, Fourze Damashii and OOO Damashii, which are all reprised in the aforementioned Kamen Rider 1 movie.

These chapters take place after Ghost and Specter obtain the Ryoma, Himiko and Houdini Eyecons respectively. Due to the Himiko Eyecon, and Makoto not being Necrom Specter, this would take place at least after episode 20, and before Makoto's departure for the Gamma world in the following episode.
