Kamen Rider Gaim

Because of the large company, Yggdrasill Corporation setting up shop in the once bustling city of Zawame; the community started to become more like a jōkamachi. 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. Kouta Kazuraba, a young man who recently quit his dance crew Team Gaim (to help his sister Akira Kazuraba), finds a special Lockseed and the Sengoku Driver to become an Armored Rider, named Kamen Rider Gaim. He must fight the sudden appearance of the Inves, but also against other Armored Riders, effectively becoming a Sengoku period-like conflict for only one victor to prove themselves that they have the right to possess the power of the Helheim Forest, the proverbial forbidden fruit. But while adamant to obtain the Golden Fruit to save the world, Kouta's goal involves him having a predestined confrontation with Kaito who desires the fruit's power to shatter the status quo of the world.
