Virtual Ring

At the ring opening ceremony, Shen Liu and Shuang Huan appeared together, causing a sensation in the whole place. The clarity was measured - indigo four in the left ring and red seven in the right ring. Dead silence. He was seven years old and looked up to find his mother. His mother didn't laugh or cry, she just quickly took her hand away from his head. In this world where one is judged by the number of rings, others practice rings by filling them in. The more full they are, the stronger they will be. His rings are tilted outwards, so the emptier they are, the better they can fit. He has no moves of his own. There are only three things in this life: catch, save, and return.
