Ichibei, I have a feeling he isn't just some run around cowboy or in a league of the royal guard. He named EVERYTHING in soul society, if he named everything that means he had to have named Hakuda, Hoho, Kido and Zanjutsu. If Ichibei named everything a role appointed to him by the King of Souls himself, the King of Souls must have been around before anything had a name, so Ichibei must have been there since their inception otherwise they wouldn't have had names and names seem to be a key factor of things in Bleach.

If you have noticed Kido have names, they have incantations, they have numbers. Now this is my crackpot theory the Royal Guard all created an important piece of history for Soul Society right, be they inventions or names? If the Soul King is the one appointing these people who is to say he hasn't made anything?
 * Soul King: The progenitor of the manipulation of Reishi and Reiryoku, he either taught Shinigami how to use it, how to manipulate it, or he is the one who put it there in the first place after all, he is hailed as some sort of God like being. I pray we dont have some wizard of Oz thing going on here where he was originally a weird human and made Soul Society or travelled there or something :/ Basically the Soul King found ways to use spiritual energy and particles, this includes Kido and Hoho perhaps, and maybe the creation of all things and ways for the balance to be undertook by Shinigami, the Senkaimon, Hell Butterflies, Hell, Cleansing, Slaying of Hollows, the creation of Hollows even? Who knows what he done?
 * Ichibei: The one who gave names to everything, he must have given the names to Hakuda, Hoho and finally and most importantly Kido and who knows, even Reishi and Reiryoku? So could he have invented Kido? How would you use the 99 Named Demon spells that require names without names? "Monk of Perception or He who calls the true name" he obviously sees things differently than others, and gives names to everything, so he may be like a father of sorts to Shinigami stuff, he just names them when they pop up or it has something to do with the integral part of the soul?
 * Senjumaru: Invented the Shinigami Robes, their importance probably pertains to something about moving between worlds? Who knows it must be important unless shinigami were just running around butt naked the entire time. Could have also invented Kido, as you weave Kido, you know "Great Weave Guard" but I think thats just a title that means she creates those fabric guardians of the Soul King Palace.
 * Nimaiya: I cant be bothered typing Oetsu its annoying, but he clearly created the Zanpakuto, and with it, the way for shinigami to bond their souls to swords, letting them cleanse hollow maybe? I think shinigami have always been able to cleanse hollow maybe with spells or Hakuda, but Oetsu weaponized it. So "God of the Sword" is true to the name.
 * Kirio: Created the artificial soul, a handy invention of course, but the meaning behind that comes into her title "Ruler of Grain", now the artificial soul revolves around the injection of foreign reiatsu to mess your own up, ejecting your body or enhancing your power. Ok so heres a theory, who said that the artificial soul is just in a pill, you inject a foreign reiatsu to enhance your own power right? What did Renji and Ichigo do when they had a meal with Soul Society's master chef? They took in her reiatsu to make themselves stronger. Who knows what this could be used for more broadly, but at least it finds a way to stop bodies of gigai laying there unconcious.
 * Tenjiro: Finally, Ok, "Demon of the Hot Spring" its cool, he invented a healing hot spring, pretty handy for bath time right? I think that invention isn't too important as a hot spring, but the theory behind the way it works is. Have you ever noticed the similarity between how the hot spring works to how healing kido works? they are fairly similar to be fair. Except the blood part. Its a concept of how healing works, not just a hot spring, the theory how the hot spring works seems like a foundation that all healing kido is derived from. He created healing-ness.
