SHinIgAmI I guess.

Appearance: No, obvious changes.
Abilities:
Ability Name: Bōryoku no sekai.
Description: Compared to the arsenal of techniques Baku'Oni grants its wielder, Bōryoku no sekai is an oddball. Once the Zanpaktou is swung, most reminiscent of a basic attack, the slash will leave an "exploding trail." While simple on the surface, the repetitive explosions do not cease; it acts as a formidable defensive ability. Much like a wall. Incoming reitsu-based attacks are swallowed up and destroyed, so long as Uri can replicate the approximate scale with her own technique. Only when something is destroyed does the trail cease to exist. In terms of limitations, it can only destroy anything that scales up to a Cero or weaker. The ability cannot be used rapidly. The technique can only negate one opposing ability per wall. [One per post].

Ability Name: Infection.
Description: True to its name, Baku'oni's fluorescent and serrated blade can infect any solid surface; whether flesh or granite. The only prerequisite being a successful cut into said material, giving the infection a means of spreading. The infection slowly spreads across any surface. It's to be noted, the infection has trouble spreading through organics, and will not spread as quickly. Only when the command "Explode Baku'Oni," is said will it ignite. The explosions are generally small in scale if an organic substance is tagged, and are incapable of destroying entire limbs alone; however, there is significant enough damage from each initial blast to render said limb useless in some cases. Its damage can be comparable to a Cero.

Ability Name: Demon's Bombardment.
Description: Orbs varying in size and density scatter across a 20m radius at most, and the immediate atmosphere of a target on its smallest scale. Bundled orbs allow for a more focused explosion around an intended target, thus grants greater damage output. Scattered orbs are only 25% of it's true power, not as devastating on a spectrum of raw destructive potential, but shouldn't be taken lightly. The scattered orbs are meant to prevent a target from escaping via Sonido, flash step, etc. It can be most comparable to a minefield, detonating once one's spiritual pressure is closest to the aforementioned orbs. Due to this, Uri has no jurisdiction over who can and cannot trip said mines, thus the technique is generally dangerous around allies just as much as a foe.
