Ryomen Sukana no Kami

The great demon god (大鬼神) of Hida, sealed 1600 years before it was released during the Great War wherein it was again beaten by the Thousand Master and his comrades. It was released again decades after when Chigusa Amagasaki used Konoka Konoe's great magic potential to summon it. However, it was quickly defeated by Setsuna, Evangeline and Chachamaru, and was sealed afterwards by the Kansai Magic Association.
