Takeru has been revived from the dead and has obtained the power to transform into Kamen Rider Ghost. However, he now has only 99 days to obtain the Eyecons of 15 heroes. Akari, who can't cope with the lack of any logical and scientific sense this situation makes, is called by her professor to where another strange event has occurred. Meanwhile, Onari, knowing that the Gamma are targeting the hero Eyecons, instructs Takeru to go wherever strange events happen and sends him to the same place. Takeru finds out from the Hermit that the next hero to appear is Thomas Edison. However, he has no clue how to summon him. Meanwhile, the mysterious man in black is meeting with an inventor. What is his objective now?!
