RYU GA GOTOKU ISHIN
Ryu ga Gotoku Ishin (released in Japan in February 2014) is a spin-off game set at the end of the Edo period of Japanese history (known as the Bakumatsu period), a period when the Tokugawa Shogunate came to an end and imperial rule was restored (Meiji Restoration).
Sakamoto Ryoma is living undercover, with a false identity, as "Saito Hajime" in Kyoto. One year earlier, on the eve of the coup d'état of Tosa, Ryoma's foster father, the man who raised him, was murdered before his eyes. The only lead he had to discover who the killer was is that he used the Tennen Rishin style of fighting. This is a style used by the Shinsengumi, so Ryoma infiltrates their ranks, becoming captain of the 3rd Shinsengumi unit, in attempt to find the killer.

Options
The options in the same order as they appear in-game. The text in bold indicates the setting the game defaults on, and text to the left and right of it are settings you can switch to. For example, the "Tips" option defaults on "Normal" and to the left there is "Few" and to the right there is "Many", so pressing left will set it to "Few" and pressing right will set it to "Many".
