Synopsis
An era when missionary forces killed just because they were skywalkers. The robot left by the thirty-sixth Skywalker Oboro and the bottle full of his life were picked up by Oboro's prophecy, the thirty-seventh Skywalker Yuu, who was a tiny cat. It was. The strongest team in history has reigned at the top of spiral divers for the past four years, and challenging the team is, in other words, winning the team that was said to be dead, 2,503. It was the thirteenth spiral diver flame, and the flame was a thin white cat. The story begins when such a ghost and flame meet.
