Because of the large company, Yggdrasill Corporation setting up shop in the once bustling city of Zawame (沢芽市,Zawame-shi?); the community started to become more like a jōkamachi (城下町,castle town?). To escape the feeling of being under castle authority, dance crews were formed by young people to bring joy back to the public. Along with this is a popular game that uses the mysterious Lockseeds that contain animals called Inves that are said to come from another dimension.
As the game becomes more popular, tears in reality begin to open that bring the Inves from their home dimension to Earth. Kota Kazuraba, a young man who recently quit his dance crew, Team Gaim to help his sister Akira Kazuraba. He finds a special Lockseed and the Sengoku Driver to become Kamen Rider Gaim to fight the sudden appearance of the Inves, but also against other Kamen Riders, effectively becoming a Kamen Rider warring states period.
The episodes in this Kamen Rider Series installments incorporate the name of a fruit somewhere, as well as 2 exclamation points in the title, one for the exclamation, and the other for the other half of the episode title.
This is the first Kamen Rider series since Kamen Rider Den-O whose title is not an English word nor based on an English word.
While Gaim Riders' motif is fruit, it is not the first series to have a fruit-motif Rider. The first one is Kamen Rider Den-OSword Form.
This Kamen Rider series does not intend to strictly follow the two-episode story arc structure that has been part of Kamen Rider since Den-O.
Most of the Riders' Transformation segments is similar to the Riders from Den-O.
With a total of at least eleven Riders known to appear in the series and its accompanying movies as of the end of October 2013, this Kamen Rider series not only has more Riders than any Neo-Heisei series but is catching up with Ryuki (which had 13 Riders), Hibiki (which had 19+ Riders) and Kabuto (which had 11 Riders, not counted ZECTroopers) as the series with the most Riders in the Heisei era and the franchise overall.
Interestingly, this series is more focused about Kamen Riders battling each other than Kamen Rider Ryuki. Another difference is that in Ryuki's story is that the Mirror Monsters are intent on killing people for survival, as humans are a source of food for them. The Inves in Gaim nearly never attack humans, except if they are in a berserker state or commanded to by their summoner.
