Koshiro's Demon (幸四郎の悪魔, Kōshirō no Akuma) is the inner demon of Koshiro Igarashi who appears exclusively in Kamen Rider Geats × Revice: Movie Battle Royale. After his emergence, he immediately becomes the target of the Desire Royale, who wishes to draw out the power of Giff from Koshiro for their own nefarious purposes.

History

When Koshiro Igarashi was abducted by Balidelo and Izangi, the two were able to materialize his inner demon. Although Ikki Igarashi and Vice were able to defeat the two aliens and retrieve Koshiro, the demon was quickly snatched by Colus to serve as a tool for the Desire Royale. The demon ended up in the hands of Kamen Rider Seeker, who absorbed it inside his body to get stronger. Eventually, through the efforts of Kamen Rider Geats and Revice, they were able to reclaim the demon and returned to Koshiro's body.

Personality

As a newborn, this demon is very eager to wander around and explore the outside world. He has a hyperactive and chatty personality not unlike that of Vice.
