Creation and Concept

In Japanese folklore, Sasuke is depicted as an Koga ninja who served under Yukimura Sanada as one of his ten heroic bodyguards the Sanada Ten Braves, and is the rival of another of the guards Saizo.[1]. Both Sasuke and Saizo's stories seem to derive from the Tatsukawa Book Collection (立川文庫, or maybe it's Tachikawa) of the early 1900s. [2]. This person was apparently associated with monkeys as his surname means "monkey jump". The word "Saru" in his name means "monkey" and "tobi" means to jump. Apparently in Tachikawa, or in various other works, Sasuke's character had a strong sense of justice (明るく正義感の強い忍者).

For Seishin, MGW approached a fictional background using a little bit of details from the folklore. She also wants to develop a rivalry, and maybe friendship between Koka's Sasuke and Iga's Saizo.


Sources for Sasuke's folklore story vary and are theorized. In Shinano Province (present day Nagano Prefecture), Sasuke, named Kokichi (幸吉), was the son of a country samurai name Sandayuu Washio (鷲尾佐太夫) living at the foot of Torii Pass. Shinano is popular for its Mochizuki Family. Sasuke was taught the Koga Ninja art by Hakuunsai Tozawa (戸沢 白雲斎), who found the boy playing with monkeys (thus his name "Sarutobi", meaning "monkey jump") in Togakushi Mountains (戸隠山). He might've been an orphan at this time. When Sasuke became fifteen years old, he became the retainer of Yukimura Sanada[3]. Sasuke and Yukimura fought in the Siege of Osaka, but fled to Satsuma after their defeat by the Tokugawa (however, in the real Seige of Osaka, Yukimura was killed in the final battle in 1615).

Another reference states that Sasuke was the son of Katsuyori Takeda, born from another wife.

Person/Qualities (Seishin)

Also known as Kokichi (幸吉, good luck). A child raised during the peak of the Warring States Period, Sasuke is filled with the passion to survive. Sasuke is very determined in a goal; he lacks calmness and he often acts without thinking. This makes him impatient towards his jester-like teacher, Tozawa. Sasuke also has a strong sense of justice (正義漢)
