Kamen Rider Ghost: Commemoration! Short Stories - Season 1 Episode 2 Strongest! Another Ghost!

Sennin recalls granting a Ghost Driver to Argos, sending him on a mission while entrusting Daigo Fukami to guide him. At the Daitenku Temple in the present day, Sennin states that his plan has fallen apart and it may be all for nothing as Daigo used the Zero Specter Ghost Eyecon. However, Sennin notes that he still has the "other Ghost", Dark Ghost, and there is still a chance that his wish will come true as he planned.
