His guess was as good as hers, so unaccustomed to levels of Soul Resonance like this that he hadn't thought of doing any sort of looking into what could be considered perfect...

Instead he rode what felt like a second wind. The stench of the chamber, his sodden, slime-dotted clothing, all discomfort was gone, replaced by that overwhelming strength and desire to wipe another potential Kishin off the face of this world. The slug was coming around and was oozing a black ichor from the injury inflicted upon it. The Madness, its hunger drove it to fight onward, kill or be killed no matter the cost. There was no shred of humanity left, and it was stupid to assume they'd find any in the first place.

Something more welled deep in him, that heightening willpower he felt when he called the Emperor seal card and was ready to call Takeji Zaiten. The slug came at him but his eyes grew steely. He took a deliberate step forward and an immense Soul Descent seemed to rattle the entire chamber, crumbling stalagmites and sending the kishin egg careening back, presumably into the far wall.

He won't even let it get that far.

"All you, Naoto!" He roared aloud, and adjusted his aim.
