Early Life

After Rina was hit by a truck retrieving the Delta case he had thrown into the street, he resolved to stop running and fight alongside the others.

Takumi then found and helped Shuji and Rina by transforming into Kamen Rider Delta and fought an Orphnoch attacking them. However he faints soon after and Rina tries to show compassion, with Shuji having doubts from Masato. When he woke, he then decides that he would rather die than become Smart Brain's ally.

Delta, Kaixa and Faiz

Shuji finally decides to enter the battle with the Orphenochs as Delta and appears as Masato begins to battle the rest of Lucky Clover. Aki dies as a result of his battle with Masato. As the story comes to a close, Takumi seems to have made the decision to fight alongside Masato and Shuji as Faiz. The three riders transform to fight Orphenochs. Later, Shuji is seen reuniting with Rina in the hospital.

After being mortally wounded by Faiz, Kaixa, and Delta's attacks, Murakami offers his life to the Orphnoch King. Smart Lady arrives summoning Masato and Takumi to Smart Brain Headquarters to meet the new President. Along with Shuji, they are shocked to discover that is is Yuji. Yuji catches up with Takumi, Naoya, and Shuji kill all Riotroopers as Faiz Axel Form, the Snake Orphnoch, and Delta respectively. With Masato killed by Yuji as Kaixa

As the gang fights Kitazaki assumed his Orphnoch form to avenge Masato's death. Kitazaki is injured by Faiz and Delta. Kitazaki is whipped by Takuma's Orphnoch form before Kitazaki is executed by Arch Orphnoch, who consumes his body. Takumi comes to the realization that Teruo and the Orphnoch King are one and the same and transforms into Faiz in an attempt to kill him. He stops his punch at the last moment, Kiba then appears, transforms into Kaixa and they duel.

Later, Takumi was saved by the combined efforts of Keitaro, Mari, Naoya (who found out from Yuji and told the others), Shuji, and Rina before being confronted by Yuji again. Both he and Yuji then have one last battle that involved their powers as Faiz and Kaixa and Orphnochs. Takumi is able to claim victory as he spares Kiba's life because he said that he is "human". With a renewed sense of living, Yuji agrees to help Takumi and Shuji take down the King using the power of the three Gears. The fight doesn't go so well when the Kaixa Gear is destroyed. Before Yuji died, Faiz managed to land a hit on the King, defeating the King and killing Yuji. After the series, Shuji, Mari, and Rina were the only surviving members of Ryusei School as now that Shuji along with Rina had run the orphanage which had previously been run by Smart Brain.

Fighting Skill

Shuji is a complete amateur in terms of fighting. This disadvantage affected him to be the weakest fighter among the trio riders despite wearing the strongest Rider Gear to be ever made. During fights, he never composed and too rushed on landing his attack. Delta Gear's strength, however, was able to protect Shuji well enough to let him survive in any fight.


He is a relatively cowardly member of Ryusei School who would rather forget about Orphnochs and go back to living a normal life. But Shuji is not a person who prefer to betray friends and when the Delta Driver was in the Ryusei School's group, it become his ultimate chance to help his friend. It is possible that Shuji's pure heart to help friends despite his cowardice has rendered himself from taking the side effect of Delta Driver.

Behind the scenes


Syuji Mihara is portrayed by Atsushi Harada (原田 篤 Harada Atsushi). Harada previously portrayed Shou Tatsumi/GoGreenIcon-crosswiki in Kyuukyuu Sentai GoGoFiveIcon-crosswiki. As Kamen Rider Delta, his suit actor was Yoshifumi Oshikawa (押川 善文 Oshikawa Yoshifumi) & Jiro Okamoto (岡元 次郎 Okamoto Jirō).

Concept Art


Kamen Rider Delta concept art


  • Shuji is one of the many 555 Riders that don't have A.R World counterpart.
  • It is theorized that unlike the Faiz and Kaixa equipment, the Delta Gear can be worn and used by anybody, regardless of whether or not they are an Orphenoch or implanted with Orphenoch DNA. However, due to the fact that Delta was never seen being used by a normal Human, this has never been confirmed.
  • The Delta Driver bears a striking resemblance to the Access Lock SIcon-crosswiki from Tokusou ExceedraftIcon-crosswiki. They are both black-and-silver handle-like transformation devices, with a spring-loaded part and an antenna.

Delta Driver in Kamen Rider Decade

  • In the episode 11 of Kamen Rider Decade, the Delta Driver appears with the Smart Buckle and Psyga Driver in the ruins of Smart Brain High School.
  • Syuji Mihara's character wasn't written in the main TV series during the time of Kamen Rider 555: Paradise Losts release.
  • He has an unnamed Rider Punch in Kamen Rider Battle: Ganbarizing.
