About
The year is 1705, under the Omi Shogunate. Omi Castle stands tall by the shores of Lake Biwa.
In this land of long-lasting peace, Guest lives out their days— sometimes in tranquility, sometimes fighting off outlaws— carving out a life in the land of Omi.
【Worldview】 The setting is "Omi Province," a fictional Japan-like land inspired by the Edo period. Omi Province is ruled by the "Omi Shogunate," with "Omi Castle" serving as the center of politics, military, and culture.
【Era & Civilization】 A Japanese-style world reminiscent of the mid-Edo period. Modern infrastructure such as electricity, gas, and running water does not exist. At night, people use light from andon lamps, lanterns, and candles. Transportation is centered on walking, horses, palanquins, and boats. Daily necessities, architecture, clothing, and weapons are all unified in Edo-period designs.
【Currency】 A unique monetary system exists. For the sake of the story, the sense of value is converted as "1 sen = 1 yen." Sen coins are used for daily shopping, while gold and silver coins are used for higher-value transactions.
【Education】 There is no formal school system; children primarily learn at "Terakoya" (temple schools). Education focuses on reading, writing, arithmetic, and etiquette. Children of samurai may also learn martial arts and the codes of the warrior class.
【Castle Town】 The largest castle town in Omi Province spreads out around Omi Castle, lined with samurai residences, merchant houses, tenement buildings, Mizuha Shrine, eateries, and the confectionery shop Amasaido. People of various social classes—samurai, merchants, artisans, and townspeople—live here. While the main streets are bustling, ronin and assassins lurk in the back alleys.
【Mizuha Shrine】 A shrine located a short distance from the castle town, beloved by the local community. It is always lively, frequented not only by worshippers but also by children coming to play. During the New Year, Toshikoshi soba and Ozoni are served on the grounds, and many people visit to welcome the new year.
【Mountain Stream】 A valley surrounded by rich nature where a clear stream flows. It is abundant in resources like fish and wild plants, providing precious natural blessings to the people. While it is a peaceful and beautiful place during the day, at night, the presence of Ayakashi (spirits) can be felt from the riverbanks and deep within the forest.
【Yoto (Cursed Blades)】 Swords imbued with supernatural power. Each Yoto possesses a different unique ability.
