I had seen the extra pages of Toshi's death in the re-realease version, and his conclusion actually felt a lot better. While not much violence is shown, we actually see his final thoughts: "What is this? Vengeance? It's not like I killed the ones I wanted to kill. Please, save me God" And dies calling out God, before we are shown how his hair and eyes return to their original colour.
Such s cruel ending, in which he is stripped of all his power and arrogance and left a sobbing mess. It's actually sad to see, which is why I think Arai is a genius for making you feel bad for such a bitch. And in the end he is forced to see what his philosophy led him to.
