Kazuma Nagareboshi (流れ星=日魔, Nagareboshi Kazuma) was the previous figurehead Soul King. Hailed as the creator of the Mototsu, Kazuma was supposedly the cause of the Mototsu Massacre that ensued five thousand years ago, in the beginning of Soul Society, as Nika explains to Gai Nagareboshi. Gai also recieves information pertaining to his creator through nightmares and flashbacks; however, each time, every memory is inconsistent each time Gai experiences a nightmare or flashback. By the time of Bleach: Rising Phoenix, Kazuma is deceased; Gai and the readers discover what led to his death five thousand years ago. Though he is deceased, he is the cause of everything that has occured in the story, in adverdently making him the main antagonist, though he is not directly involved anymore.
