Shiba Isao

Shiba Isao was a sensei of the Kinenhi martial art.

Student
Isao was the most skilled student of Shiba Kyukyo, the only sensei of the Kinenhi martial art. During the War Against Shadow the dojo became an attractive target in the Lying Darkness campaign to wipe out the Empire's history and traditions. The old master and his students were attacked by minions of the Shadow, and Kyukyo's dojo was gone, as if it had never been.

Kinhei's Last Remmant
On the night when the last Kinenhi dojo was destroyed, Kyukyo ordered to flee Isao. While his brethren stood against the darkness, Isao left the monastery so the style might live on.

Sensei
For years Isao sought out new students in a secret, rebuilding a dojo at Yoake Mura. During the War of Spirits the forces of the Steel Chrysanthemum threatened the Phoenix Clan, so the Kinenhi students could hide no longer. They defeated enemy forces near the dojo. Phoenix Clan Champion Shiba Tsukune rewarded Isao for his heroism, and ordered to build a new Kinenhi dojo near Shiro Shiba.
