Kyofu's Last March

Kyofu's Last March was an assault on the forces of Kyoso no Oni by Kyofu and the Damned in 1168.

Kyofu's Request
Kyofu, the former Hida Kuroda and onisu of fear, approached Crab Clan Champion Hida Kuon on behalf of Daigotsu and himself with a proposal that would benefit the Lost, the Crab Clan and the Empire as a whole.

Kyoso no Oni had been threatining to usurp Daigotsu for years, leading finally to an armed conflict. Kyofu proposed that since Daigotsu was a man of some honor, he posed a lesser threat than the sinister Kyoso. Kyofu asked permission to lead the Damned into the Shadowlands in a suicide assault. Kuon was unwilling to trust an onisu with the Crab's resources until Omen proved Kyofu's honestly benevolent intentions.

The March
Kyofu and his men set out against the Shadowlands soon after. To prevent such a large army from surrendering to their Taint Kuon sent several tsukai-sagasu with them, including Kuni Daigo. Kyofu was also given the sword Kettei, Xing Guo's final gift to the Crab, to wield. As the men would not be returning Daigo was tasked with bringing the blade back to Kuon after the battle.
