"Sky Walking seals?" Kagome-sensei said, shaking the paper clutched in his right hand at Hazō. "You want to modify the Five Seal Barrier to use only one seal? And you want to modify my Lesser Barrier Formation?! Madness! It's obviously madness and craziness and—" He paused, head cocked in thought. "Well...I mean...hm. You could dampen the harmonic on the...no, that wouldn't work. Maybe if you deconvolved the...no, no, no, that might just turn your brain inside out. Ooh, you could...no, that would be stupid. Hm." He pulled a bit of charcoal out of the fire, flipped Hazō's notes over, and started scribbling on the back in complete obliviousness of the genin's horrified look.
The entire group stayed silent, watching with a wary amusement as Kagome scribbled on the paper for several minutes.
"Ha!" he said finally, sounding thoroughly satisfied. "I was right: it's obviously madness. Not going to happen." He waved the sheet at Hazō dramatically. "This? This crazy idea on how you can get rid of four of the seals by decohering the resonances through the fifth and twelfth dimensions? Ridiculous! Absolutely ridiculous! Don't you think people have thought of this? Of course they have, and most of them got turned into goo, or eaten by tentacular horrors from beyond space and time, or both! People have wanted a one-seal variant on the Five Seal Barrier since forever! If it was as simple as decohering the resonance on two dimensions, don't you think someone would have thought of it? It's obviously wrong! Obviously!"
