Just as Danzō stared blankly at the Mangekyō moon hanging in the sky, Shisui's genjutsu reached its climax.
"Kotoamatsukami: Radiance."
Shisui's voice echoed through the genjutsu space. The moon overhead erupted with blinding golden light, and an almost endless amount of ocular power burst forth from it, filling the entire illusionary space.

"Crackle, crackle, crackle..."
A series of crackling sounds rang out as Shimura Danzō's clothes were ignited by the extreme heat and began to burn.
