This article is about a/an episode in Kamen Rider Ghost.

Reverse! Mysterious Science! (逆転!神秘な科学! Gyakuten! Shinpi na Kagaku!) is the eighteenth episode of Kamen Rider Ghost. It features the debut of Necrom Sanzo Damashii and Igor's Gamma Superior and Gamma Superior Knife forms. It also features the final appearance of Ghost Himiko Damashii.


When the spirit of Himiko isn't the cause of the strange happenings in the city, the Himiko Eyecon leads Takeru to the Gamma World for a revelation. With Makoto also out of action during the continued attacks on young women, Akari and Onari step forward to try to discover the reason for the attacks, but Akari must first improve the Shiranui formulation.

Ghost Eyecons

Gamma Eyecons

  • Eyecon Used:
  • Gamma Form Used:
    • Igor
      • Gamma Superior Knife, Gamma Superior Perfect


  • When Alain transforms into Necrom Sanzo Damashii, some of the Mega Ulorder's sounds were not played, while others were simply obscured by the louder Toucon Boost transformation announcements.
  • When Takeru transforms into Ghost Toucon Boost Damashii to fight the Knife Ganma, he is not shown pulling his hood back, yet when the shot returns to him to show him holding the Sunglasseslasher, he is seen with the hood down.
  • When Ghost changes to the Himiko Damashii, the "Kaigan" sound is not heard.
  • When the Newton and Himiko Eyecon are inserted into the Sunglasseslasher, it announces "Mega Mabushii" instead of the expected "Mabushii" for lacking the Toucon Boost Eyecon.

  • When Takeru transformed into Ghost and Alain transformed into Necrom, the way the Toucon Boost Damashii and Sanzo Damashii moved around them and briefly fought resembled when the Musashi and Nobunaga Damashiis battled back in Fast Shooting! Legendary Gunman!.
  • This is the first episode where Necrom does not assume his default form.
  • This is the first time Specter doesn't use the Gan Gun Hand.
  • This is the only time Igor changes from Gamma Superior Perfect to Gamma Superior Knife.
  • Because he doesn't know that Takeru is a ghost, Yasushi looks at Takeru like he has seen one.
  • When Takeru is teleported to and from the Gamma's World, there was a cube and square distortion as he did so. This could subtly be referencing Zyuohger, which premiered alongside this episode.
