Nisshoku Reito. Quite an odd name. Nisshoku means Eclipse. Reito means beautiful, dark moon. The last living member of the Nisshoku family. The last living user of the Eclipse breathing technique. The eclipse Hashira. But he didn't start out as powerful as he is now. He started off as a scared little boy, his family slaughtered. His siblings dead. His hashira dad, dead too, died at the hands of Muzan. His mother, died. If his dad hadn't challenged Muzan and tried to kill Muzan (clearly failed), they'd all still be alive. He would be okay.
