These are references that I used to create the manga.

Fujiwara no Hidesato (藤原 秀郷) was a kuge (court bureaucrat) of tenth century Heian Japan. He is famous for his military exploits and courage, and is regarded the common ancestor of the Ōshū branch of the Fujiwara clan, the Yūki, Oyama, and Shimokōbe families.

Hidesato served under Emperor Suzaku, and fought alongside Taira no Sadamori in 940 in suppressing the revolt of Taira no Masakado. His prayer for victory before this battle is commemorated in the Kachiya Festival. Hidesato was then appointed Chinjufu-shogun (Defender of the North) and Governor of Shimotsuke Province.

Lake Biwa -(琵琶湖, Biwa-ko), formerly known as Ōmi (淡海) Lake, is the largest freshwater lake in Japan, located in Shiga Prefecture (west-central Honshū), northeast of the former capital city of Kyoto. Because of its proximity to the ancient capital, references to Lake Biwa appear frequently in Japanese literature, particularly in poetry and in historical accounts of battles.

Ryo-wo -Ryūjin (Japanese 龍神 “dragon god”), also known as Rinjin and Owatatsumi) was the god of the sea in Japanese mythology. He was a dragon, symbolic of the power of the ocean, had a large mouth, and was able to transform into a human shape. Ryūjin lived in Ryūgū-jō, his palace under the sea built out of red and white coral, from where he controlled the tides with magical tide jewels. Sea turtles, fish and jellyfish are often depicted as Ryūjin’s servants.

Ryūjin was the father of the beautiful goddess Otohime who married the hunter prince Hoori. The first Emperor of Japan, Emperor Jimmu, is said to have been a grandson of Otohime and Hoori’s. Thus, Ryūjin is one of the ancestors of the Japanese imperial dynasty.
