But even defenses of this strength had been shattered in an instant?
What concerned Urahara Kisuke even more was that Reikaku Aizen had known that Dankū, practically the "strongest defensive Kido," could not withstand Reikaku Captain Ailin's attack.
Only after casting six consecutive Dankū had he managed to defend against Reikaku Captain Ailin's attack.
Just from the fact that it had shattered five Dankū barriers cast by Reikaku Aizen, one could tell exactly how powerful Reikaku Captain Ailin's previous attack had been.
At the very least, Urahara Kisuke felt that even if he fully incanted Hadō #96, One-Hit Kill: Funeral Pyre, it would not possess even half that attack's power.
"Faintly revealing a turbid crest, arrogant and untamable talent..."
"Surging tide, denial, paralysis, an instant, obstructing sleep..."
"Crawling iron princess, mud doll that endlessly mutilates itself..."
"Unite, rebound, extend to the earth, and know your own powerlessness!"
Amid the thunderous roars, Reikaku Aizen's chanting of a Kido incantation could faintly be heard.
Upon hearing Reikaku Aizen's chant, Urahara Kisuke's brow creased with concern.
That was the incantation for Hadō #90, Black Coffin!
With Reikaku Aizen's mastery of Kido, a fully incanted Black Coffin was powerful enough to instantly kill most captains.
"Hadō #90—Black Coffin!"
"BOOM! BOOM! BOOM!"
As Reikaku Aizen let out his final roar, a black cube over ten meters tall materialized around Reikaku Ailin.
To Urahara Kisuke and the others' surprise, Reikaku Captain Ailin took no defensive measures whatsoever against this attack and was simply engulfed completely by the Black Coffin.
"Screech, screech, screech..."
In an instant, the Black Coffin's power erupted in full. Countless Shadow Blades pierced outward from within it, forming enormous crucifix-like shapes around its exterior.
Then, having unleashed its full power, the Black Coffin slowly dispersed.
Yet what shocked everyone present was that even
