A special grade disease cursed spirit, the Smallpox Deity is conjured by Pseudo-Geto through Cursed Spirit Manipulation during the Shibuya Incident. It is set loose on the sorcerer Mei Mei to test whether she is worthy of facing him.
Sizewise this curse sits close to that of a person. Pale fur smothers the upper half, blanketing most of its face and spilling down the back, and the mouth bristles with sharp teeth flanked by two heavy tusks. Off the end of that fur runs a tail marked by dark triangular shapes, and it links to a hovering sphere that forms the spirit's lower portion as it floats. Bumps of pox dot the two thick, muscular arms reaching out from its frame.
While bound by the Cursed Spirit Manipulation that Pseudo-Geto wields, the curse retains almost no intelligence of its own. Pure instinct drives every move it makes. It locks onto whichever enemy gives off the densest cursed energy and throws its attacks at that figure alone. That mindless, instinct-bound focus is exactly the weakness Mei Mei exploits once she has an ally with her on the field.
It stands as one of merely sixteen registered special grade curses, a tier rare enough to mark it as extraordinary, and Pseudo-Geto praised it as the finest in his collection, using it as a yardstick for the grade 1 Mei Mei before he would meet her himself. Proof of its caliber lies in its full Domain Expansion, a graveyard space fitting its disease motif that instantly catches anyone it marks. The curse's unnamed gravestone technique starts by penning the victim within a cramped coffin; the spirit then drops its left fist into its right hand, dropping a towering tombstone that crushes and buries the coffin underground. A countdown from three follows, and should it ever reach one the target perishes of smallpox. Sealed inside the domain's guaranteed strike, the method ensures death once its terms are met. In the Shibuya Incident, Pseudo-Geto's manipulation of cursed spirits had it ensnare Ui Ui together with his sister Mei Mei inside that domain, boxed her in a coffin, and shattered it under a great boulder, though she escaped. It kept up the assault until Ui Ui let his cursed energy loose, drawing its aim onto him, only for his Simple Domain to turn it away. Mei Mei then baited it long enough for one of her crows to exorcise it, a kill that cost the bird its life.

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....

Five Bleach female characters, ranked and settled. Yoruichi sits at number five, the spot nobody expects, and our number one is an Arrancar with a soft heart....
