Yamamoto founded the soul society 2000 years before Bleach, and is thought to be the best Soul Reaper there ever was

Yamamoto founded the soul society 2000 years before Bleach, and is thought to be the best Soul Reaper there ever was. But, who knows if he had any help? Inspiraton? Who originally started the Soul Society, and taught Yamamoto? No one knows, until the day a mysterious beauty appears infront of a Gotei 13 meeting along with there lieutenants. Who is this girl? Why does only a fraction of her spirit energy bring the entirety of Soul Society to the floor, including Yamamoto? Why is he taking orders from her? The execution Zanpakuto isn't REALLY the strongest? And more importantly, where has she been all this time?

Ohayo, everyone! Welcome to my Bleach fanfiction! This idea just popped into my head, I hope you like it! This is the hardest profile I've ever done! Anyway, I have a request of you all, PLEASE MESSAGE ME WHO YOU WANT YOUR CHARACTER TO END UP WITH!! Anyhow, On with the Profile!

THE STRONGEST ZANPAKUTO IS YOURS ACTUALLY, NOT THE EXECUTION ZANPAKUTO!!
Meaning: Heaven God
Release: "Sing into the Stars."

Looks: as perfect as I can make you, which is PERFECT. LOL.

Your shoes are traditional Shinigamis and your sword is placed on your right hip (like Sasuke's from Naruto in Shippuden.)

I THINK that's it… but if you need more, message me, m'kay? Oh, and like, I own nothing.
