Teikoku was originally led by Kidou. Their coach was Kageyama Reiji- and thanks to his superior coaching skills (albeit with the help of dirty tactics) - they continued to win for 40 years without a single loss in the Football Frontier. Fortunately, Kidou discovers Kageyama's deceitful and manipulative personality, and he decides to part ways with Kageyama's coaching. The rest of the team follows Kidou's footsteps soon after, and leave Kageyama's side.
