he can reach the Presenters. After learning the Dark Nebula would also destroy AGHS and the city, the Kamen Rider Club eventually succeed in stopping Gamou. Mitsuaki Gamou , initially credited as the , is AGHS's egocentric and charismatic school board chairman who often uses space metaphors in his speech. Despite his charming personality, he lacks friends as he views the concept as beneath him. As a child, Gamou heard the Presenters' call around the time of the Apollo 11 exploration, motivating him to join NASA, the Russian Federal Space Agency, and the OSTO in an attempt to meet them. Twenty years prior to the series, while working for OSTO, Gamou found the Presenters' Core Switch alongside Rokuro Utahoshi on the moon. The pair cracked the Switch's puzzle, but clashed over how to contact the Presenters, with Gamou seeing Rokuro's Fourze System as a time-consuming dead end before he went on to develop the Zodiarts Switches. Three years after finding the Core Switch, Gamou tasked Kuniteru Emoto with getting the Zodiarts Switches from OSTO's lunar station and murdering Rokuro, though Emoto abandoned Rokuro on the moon instead. A decade prior to the series, Gamou received funding from Foundation X to build Amanogawa High directly under "The Hole" ostensibly in order to foster a love of space exploration in future generations while secretly utilizing the school to create and raise Zodiarts to gather the Horoscopes for the day he meets the Presenters, which he refers to as the . To this end, he became one of the first Horoscopes, the . Throughout the first half of the series, Gamou secretly uses AGHS to encourage the students to pursue individuality and whatever they please in the hopes that they can evolve and become Horoscopes. Additionally, he orders his subordinates not to eliminate Kamen Riders Fourze and Meteor as they provide an additional factor towards his Zodiarts' evolution. After Emoto reveals his true colors and aids the Riders however, Gamou reveals himself to the pair and searches for the Core Switch. When Utahoshi's son Kengo thwarts his Day of Awakening, Gamou destroys the Core Switch to kill Kengo before renewing his plans, only for Fourze to defeat him. Gamou accepts the Rider's ideals and friendship, but begins to evaporate into stardust due to years of working directly with Cosmic Energy. Before he dies, he asks the Kamen Rider Club to meet the Presenters
