The next hero seems to be Billy the Kid. Takeru immediately gets Sennin's clue and at the same time, a new client comes to the Laboratory saying that something is wrong with their best friend. At the same time, Narita and Shibuya bring information of a sighting of the Mysterious Man. Akari and Onari follow the clue to the Mysterious Man and see him talking to Specter. The man, whose name is Saionji, talks about "what happened 10 years ago..."

All the inhabitants of the apartment building the friend lives in seem to be acting strangely as well. Takeru investigates and a Gamma appears. Takeru transforms into Ghost and fights but Specter appears. Takeru, who now has lost all fear, confronts Specter as well.

The Fukami siblings, Makoto and Kanon, are approached by Alain and Jabel. Makoto attempts to fight Jabel but is overwhelmed, which results in Kanon being kidnapped. Knowing that he can't beat Jabel as he is, Makoto tries to use the Eyecon of the "Escape King", Houdini, even though it never let him use its power before.

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.

Takeru tries to teach the Gazai Gamma the meaning of friendship, but must also deal with both Igor and Necrom Specter seeking to destroy the "incomplete" Gamma.

The Dream World Takeru and the others were investigating was another one of Igor's schemes. Jiro, brother of Akari's professor, Yuichi Katagiri, insists that he won't leave the Dream World. The brothers' squabble catches the attention of the Grimm Eyecon and the Brothers Grimm themselves start having a discussion about fun. Due to this, Grateful Damashi can no longer be maintained and the Eyecon is stolen. A new Gammaizer has appeared as well.

In the meantime, Makoto and Alain, tasked with protecting Takeru’s body, confront a Gammaizer themselves in the real world.

The meeting between Adel, Alia, and Igor commence. At the beginning of the debate Igor gets a blow from Alia. While Adel "defeats" Alia when she changes into Dark Necrom, his strength is still not comparable with the Gammaizers. Takeru encounters a debate in the house of a Father and a daughter. After arguing they were attacked by a Gammaizer. The Gammaizer appeared to look weak compared to the previous but the soul of the father and daughter swapped bodies. Billy the Kid appears and enters the body of Kanon. Takeru works to help resolve problems between the father and daughter. The father turned out to have a new relationship with the fugitive known by Mayu the daughter. While the Dad was in the Gammaizer's body, Mayu in her Dad's body, and the Gammaizer in Mayu's body, can Takeru and the gang solve this mystery and find out what he's after?
