Toshiya Miura (三浦 俊也, Miura Toshiya) is a minor character in Kamen Rider Fourze and a member of the AGHS American Football team until he was kicked out. Miura became the Orion Zodiarts (オリオン・ゾディアーツ, Orion Zodiātsu) to exact his revenge until he was defeated by Kamen Rider Fourze. Upon coming back to schoo,l he joined his girlfriend, Mari Yamamoto, in the photography club.
By heart, Miura is a good person but there are times where he loses control of his emotions. After the Orion Zodiarts was defeated, Miura was filled with so much guilt about what he had done; he stopped going to school. He also had gained an addiction to the Cosmic Energy of a Zodiarts Switch, which is yet another reason he stopped coming to school in order to protect the students and himself. After being reminded of his life before the Zodiarts Switch, Miura gets over his addiction to Cosmic Energy.
Miura at some point made it into the school's American Football team, but Takato Daimonji had his son Shun (the captain) demote him to equipment manager. To exact revenge, Miura acquired the Zodiarts Switch that allowed him to become the Orion Zodiarts from the Scorpion Zodiarts. He planned to attack Shun for ruining his football chances until he was defeated by Kamen Rider Fourze. Miura is then told by Gentaro that he doesn't have to resort to such drastic methods.
Miura is later hospitalized afterward and for the next few months, he stops coming to school filled with guilt. He declines every requests he gets to come back to school, from the Kamen Rider Club (even after Shun apologizes to Miura) to his own girlfriend, Mari Yamamoto. Miura is then targeted by the Scorpion Zodiarts again to force him to become an Orion Zodiarts again due to his addiction to Cosmic Energy presenting him with a new Zodiarts Switch that quickly enters its Last One state. When Fourze arrives, the Scorpion Zodiarts tells him to meet at the first place they met.
Miura accepts the offer while telling Gentaro and co. to leave him alone. But Miura sees Mari's photo of him while remembering his life before the Orion Switch. After the Scorpion Zodiarts drives the club off, Miura encounters the Horoscope and has the strength to outright refuse the Switch. The Scorpion proceeds to kill Miura, until Fourze appears and defeats the Horoscope. Miura then returns to school the next day joining Mari in the photography club.
