Tawara Touta is one of the "Camelot" Singularity Servants that appear to aid Ritsuka Fujimaru. Tawara Touta was revered as the founder of martial arts in the Kanto provinces. Later introducing himself as Fujiwara Hidesato, he suddenly won fame by shooting Taira Masakado.

Tawara Touta was a brave soldier who performed many achievements while wielding the golden long sword handed down from his ancestor, Fujiwara Kamatari. A certain day, he was asked by the incarnation of a dragon god to exterminate the great centipede of Mount Mikami. He spit on his arrow, offered a prayer to Hachiman and splendidly exterminated the great centipede, big enough to make seven and a half turns in a mountain - with a bow and arrow. After receiving a rice bag that never runs out of rice as thanks from the dragon gods, it has been told that Tawara Touta went through hundreds of oni-exterminations and finally shot Taira Masakado, who was an immortal demon.
