Guuji Chishiki no

This enigmatic figure is the Shrine Priest of Knowledge, revealed as the true antagonist manipulating Kazane and Ryuusai. Having previously faced opposition from Seimei and his spirit summons, he has returned to unleash the Gates of the Underworld. Through manipulation and deception, he orchestrated events to gain access to the underworld, even using Rikugou's soul and Touda's blood to achieve his goals. His defeat came unexpectedly through Kazane's necklace.
