The 2013-2014 Kamen Rider series; the fifteenth entry in the franchise's Heisei era and the twenty-fourth series overall. The head writer is Gen Urobuchi of Fate/Zero, Puella Magi Madoka Magica and Psycho-Pass fame.
In Zawame City, the suffocating presence of the Yggdrasill Corporation has led to the city's youth forming competing street-dance crews as a way to bring energy and excitement back into their lives.
Another popular activity is a Mons game that uses fruit and nut-themed padlocks called Lockseeds to summon tiny creatures called "Inves". As the game becomes more and more popular, strange dimensional tears begin to open around the city to the mysterious Helheim Forest. When an Inves consumes a fruit from this forest, there is a chance of it evolving into a more powerful form but at the risk of losing all control and going on a hunger-induced rampage.
Kouta Kazuraba is an earnest young man who quits his dance crew - Team Gaim - so that he can find a job and support his sister. When he is caught up in the attack of a berserk Inves, Kouta stumbles upon a strange transformation belt and Lockseed, which he uses to transform into "Armored Rider Gaim" and defend his friends and the city.
However, it is not as simple as that. There are many other Armored Riders in the city with their own motivations and sense of justice, and soon a modern version of the Warring States Era erupts between the masked warriors.
