User blog comment:Purple sky4/who invented Kido?/@comment-5775318-20130501174934

ok, to claer somthing up; if we look that the titles the royal guard have, then we can guess what they made, the ruler of grain/Kirio Hikifune, she made the mod soul by melding reishi into and other object, like she does with her cooking. Hot Spring Demon/Tenjiro Kirinji, he invented the white bone, and blood hell springs which heal the spiritual forms completely but drains them of all reiatsu. god of swords/Oetsu Nimaiya, invented the asauchi, which become the zanpakuto for every single shinigami and can sense the locations of all of them. then there is Sejumaru Shutara, The Great Weave Guard, which could mean that she made the shihakusho, the tentoken cloak, or somthing with have no idea about. So therefore its logical to assume that Osho, MIGHT have been the one to make the standard forms of kido, but we wont know.
