Several hundreds years have passed since then. Renton is a boy who lives with his grandfather in the Tower Country Belforest. He has one major complaint about his life. As the son of the great hero Adrock, who saved the world from the disaster known as the Summer of Love at the cost of his own life, Renton shoulders a burden trying to live up to this name. Furthermore, his grandfather is a mechanic and expects Renton to take over the family business.
His only mental escape is Liff, a sport where one glides through the Traver. Renton yearns to follow in the footsteps of Holland, a charismatic Liff Rider, and to travel around gliding like him, believing that a big wave of change will come to him some day.
