The Tiger are descended from the Yotsu, a ronin family created during the eleventh century. The daughters of the family founder were appointed as governors of the city districts in the Imperial capital, Otosan Uchi, and after the destruction of the city by the Dark Lord Daigotsu during the Four Winds era the growing family assumed responsibility for the ruins.
In the Heroes of Rokugan timeline, the Spider Clan is eventually cleared from the ruins of Otosan Uchi and the Yotsu fight in the vanguard of that effort, hunting Lost and Shadowlands monsters through the streets of the wrecked city. Afterward they are proclaimed the Tiger Clan and given permanent responsibility for protecting the city and ensuring the power of Jigoku can never again be unleashed within its boundaries. Sadly, the process of cleansing the city of Taint also makes it unable to support crops or animal life, so in order to live and fulfill their duties the Yotsu are forced to hire themselves out as mercenaries across the Empire. This allows them to earn enough koku to scrape by, especially since their skills at hunting foes through cities make them quite popular as yoriki to magistrates.
The clan colors of the Tiger Clan are yellow and black. Their mon shows a stylized image of a tiger springing from ambush.
