Kuma, as any other former slave of the Celestial Dragons, was branded with the “Hoof of the Flying Dragon” on his back. In his entire life, he had never tasted total freedom (emotional, physical, whatever), he even lost his own personality, he “died” and still he was a slave.
But.. In the last moments of his life, when his own will predominated all boundaries, when he punched the one who ruined his life and his family… Saturn stabbed his back and by that destroyed the mark that symbolically marked him as a slave.
Living his whole life oppressed, Kuma even after losing his mind, personality and almost everything, decided to make his own decisions and only in that moment he died.
