The Most Brilliant Orihime Inoue Arc That Never Was.
When we study Hogyoku and Hollows, we learn that the mystical gemstone is an artifact forged by Kisuke Urahara to manifest the deepest desires of the person wielding it, a relic of nearly omnipotent power that Sosuke Aizen claimed Orihime Inoue could affect and implied she could seize but it was never explored.
My intuition concluded and guide me into drawing the fetters and pulling the strings so it is finally unveiled why Orihime was of such magnificent importance and never truly realized it, just as Ulquiorra was infatuated with her and still insisted it was but an unusual curiosity in humanity.
Hueco Mundo exists as a contrast to The World of The Living, as the residence of isolated souls surrounded by death and despair and dread. Ulquiorra and Orihime, become polar opposites, and the very premise of the forbidden love story in "Tsukuyomi and Amaterasu" romance is implemented so beautifully that it resonates much better than what Kubo intended to grant Ichigo and Orihime.
Ulquiorra being constantly anchored to a realm governed by the crescent moon, and carrying his duty as a phlegmatic, stoic, withdrawn warden whilst Orihime is from a world blessed by the blessing of the dawn, and she herself is a radiant being full of passion and hope and kindness.
When Ulquiorra is mortally wounded by Ichigo, and silently confesses to Orihime with those eyes that long for a life to spend with her, that is what motivates Orihime to remain in Hueco Mundo and engage in her own battle to prevent Ulquiorra from being claimed by the pith of oblivion.
A desire that the vasto lorde and the she-human share, and a wish from Orihime that is heard by the heavens. Hogyoku answers her calling, and escapes from Kisuke to reach for Ulquiorra in order to rest within the void of his very being--as the very evidence of his attainment of heart--as the manifestation of his love that Orihime tabernacles within the pith of her existence.
That brings forth an intriguing:
"Did Aizen foresee this event? Was this a prophecy of his?"
Ulquiorra, henceforth ascends to an entity beyond a existence of vasto lorde and hollows, and the second chapter of his redemption begins.
This purifying transformation releases Orihime of the belief that she is only capable of mocking her beloved ones into beastly forms after having witnessed the terror of Ichigo becoming vasto lorde, and bear witness how she could be present in forging a majestic presence in a being that was certain of his soullessness.
To summarize it all, this is just me putting two minutes so i mold a tragic spectacle into a poetic masterpiece. I merely am not full of vitality to bring this idea to life.
