Kengan Omega

Two years since the events of Kengan Ashura took place, a young man named Narushima Kouga wants to enter the Kengan matches, looking for Tokita Ouma for some reason. He starts to work under Yamashita Kazuo when he ends up meeting Gaou Ryuuki, a splitting image of Ouma. As a great showdown between the Kengan Association and Purgatory occur, another underground organization comes into place.
