(Koutetsu Hold)
Actually, the noblewoman's kido was the exact reason the assailants decided to switch to a more guerilla style of assault. She does catch one in the flames, perishing instantly... but they're all moving between the buildings outside and effectively using cover. Plus, most of them are on opposite sides of the building, steadily demolishing it with dynamite.
Of course, as the shinigami scatter, something leaps through the hole in the wall after the kido, clad fully in armor yet disturbingly nimble, wielding a shovel that seems repurposed into an axe. It cuts through the green flames with an aura of energy around it, swinging for the Noblewoman's head, speaking with an echoing, ambiguous tone.
"Yeh nobles 'ave 'ad more'n yer fill fer cen'tries! S'time we took back!"
