Daidoji Shigehira

Daidoji Shigehira was the youngest son of Daidoji Hira, the youngest brother of Daidoji Daimyo Daidoji Kamei.

Hira's Maddened Behaviour
In 520 Hira began to act erratically, exhausting the patience of Kamei. The daimyo ordered his brother to commit seppuku, but Hira fled along with forty-four bushi from the Shiro Daidoji guard, leaving a message behind: "You did not set a date for my death, brother. Seek me in the Uebe Marshes if you wish to hasten it."

Foxfire War
Incensed, Kamei sailed down the coast to the Uebe Marshes to chase his brother. In the unfamiliar terrain, his troops were slaughtered during the Foxfire War with trap-laying and ambush strategies developed by Hira. After several months, Kamei retired to Shiro Daidoji, and found Hira's body in his former quarters, dead by seppuku. Arranged around him was a model depicting the most treacherous ambush points in the Marshes in the same scale as those in the Daidoji Library, and the message: "Do not let the food and drink of peace make the belly of the Daidoji grow fat. Seek my son in the marshes." Kamei retired as a monk, and his daughter and heir, Daidoji Kasako, hunted Yasuhira. Within three years she had brought her cousin to bay. Yasuhira was captured and executed, surrounded by new woodland models and maps and the instruction: "My brother Shigehira and my men spit at you from the Wall above the Ocean."

Death
Shigehira followed the Blood feud against Kasako and his followers from the mountain range. Kasako's younger brother Daidoji Hanzo was the commander of the Daidoji troops who chased him, and killed Shigehira during a yari duel between the two leaders on a cliff path. With his death Hira's line had been consumed and the war was concluded.

Aftermath
Those troops that had helped the current daimyo defeat Hira's followers, were proclaimed the Hiramori family, vassals to the Daidoji. The family was named the "Forest Hira," an ironic joke at the traitorous Hira's expense.
