Mimihiko is one of the main villains in Cho Kamen Rider Den-O & Decade NEO Generations: The Onigashima Battleship alongside his brother, Kuchihiko.


The younger Oni Brother, Mimihiko was sent by his brother into the past in order to rewrite history. He is armed with the Silvery Kanabō, which also enables his transformation into a silver dragonfly-like Shilubara.

He briefly appears in Kamen Rider Decade in the World of Den-O to acquire the vase for his brother's agenda, getting it while Decade and Den-O are distracted with their fight as New Den-O arrives to stop Shilubara before he took the item back in time. He later travels to 1980 to steal the Trump Stone, but is forced to wait for his brother to acquire it in their time.

Once the Trump is complete, Mimihiko pilots the Demon's Warship back into the past where he fights against the riders with his brother, sacrificing himself to save his brother from Cho Den-O's attack.
